They can be brought about by issues identified with the embellishment cycle, material use, tooling plan, or a mix of each of the three. Now, we shall take a look at the most widely recognized mistakes identified and what you can do to prevent them.

Plastic Injection Molding

Stream Lines or Flow Marks in Plastic Injection Molding

What do we mean by streamlines?

Streamlines are waves, streaks, or lines that are stained when contrasted with their surroundings. These are generally seen near the 'entryway', where the liquid plastic enters it through injections. They don't influence the usefulness of the item, however, make the item lose its aesthetic.

How to prevent it?

  • The easiest response to this issue is to fasten the injection molding process
  • The weight and temperature of the material infused into the form can be changed so the plastic can totally fill the shape prior to setting.
  • Another procedure is changing the area of the shape entryways of the injection units where the liquid plastic starts to stream in during the assembling cycle.
  • Applying an oil to the surface will help the progression of the liquid thermoplastic material.


Burn Marks

What are burn marks?

Burn marks are dim shaded blemishes on the edges of the item. However, they don’t have any bad effects.

How to prevent it?

  • Burn imprints can be maintained by a strategic method of lessening the injection speed and holding the weight of the embellishment device. This will forestall air bubbles getting caught inside
  • Gas vents can be augmented to encourage a simple getaway of caught air.
  • Decreasing the temperature of the form and water-driven chambers can also help forestall burn marks


What does warping mean?

Warping happens when various pieces of an item cool and sets unevenly. The resultant item is distorted with twists in it.

How to prevent it:

  • Make the cooling cycle slow so that there is no weight on the liquid plastic material as it cools.
  • Change the temperature during large scale manufacturing.
  • Use materials that don't recoil unnecessarily during cooling.

Vacuum Voids/Air Pockets

What do we mean by air pockets?

These are caught air bubbles in the finished item. Despite the fact that this isn't viewed as a significant imperfection, it could make it a bit weak.

How to solve it effectively?

  • The blow plastic injection compel should be expanded to remove the caught air that rises out of the shape.
  • Select a material with low consistency so that air bubbles are not shaped in it without any problem.
  • Guarantee that there are entryways close to the thickest pieces of the shape so the plastic doesn't cool too early.

 Plastic Injection Molding Sink Marks

What are sink marks?

These are little miseries shaped in the plastic item. This typically happens when the internal portion of the segment cements quickly.

How to prevent this?

  • A basic method to amend this issue is increment the weight so that there is more opportunity for the material to cool

Weld Lines

What are the weld lines?

These are lines that show up on the outside of the plastic item. It happens when liquid plastic emerges from various channels at one point in the form and bonds feebly to one another. This outcome is debilitating to the plastic part at the weld line.

How to fix it?

  • The material temperature should be expanded so that there is uniformly cementing of the material
  • The infusion speed and weight can be expanded to guarantee that there is no untimely cooling inside the shape.
  • A material with lower thickness can be picked as the crude material so it streams effectively and doesn't cool rashly.


What does the term ‘Jetting’ mean?

Jetting is brought about by an unexpected wave of liquid material, which then begins to cool before the remainder of the hole is filled, prompting unusual changes on the outside of the item.

How to prevent it?

  • One approach for streaming in plastic segments is to decrease the infusion pressure. This will forestall the squiring of the liquid material into the form.
  • The temperature of the form and material can be expanded so that the wave stream doesn't cement quicker than the remainder of the material.
  • Ideal planning of the shape and responding screw so that streaming doesn't happen is another solution.

Plastic Injection Molding

Plastic Injection Molding Discoloration

What is discoloration?

Discoloration is the point at which the completed plastic item is of unexpected color in comparison to what it should be. Discoloration doesn't influence the quality or working of the completed item.

How to get rid of discoloration?

  • Ensure that all pieces of the plastic injection molding machine like the container, spout, form, and so on are altogether cleaned before you run a new group.
  • Cleanse the machine routinely to eliminate any remaining material.
  • Ensure that your provider provides shading specialists with adequate warm solidness and that your crude material is properly blended

Surface Delamination

What does surface delamination mean?

Delamination is when thin layers from the completed item begin to strip away from its surface. This is a major issue, as chipping of the surface material would, in the long run, cause the item to debilitate and lose its usefulness.

How to prevent it?

  • Ensure that the material has been dried appropriately prior to stacking it into the container of the machine.
  • Be cautious of the capacity and treatment of the crude material to avoid pollution.
  • Overhauling of the spout would be beneficial in ensuring that toxins don't enter the shape

Short Shot

What does the term ‘Short Shot’ mean?

During the process of plastic injection molding, if the liquid plastic material doesn't fill in the form entirely, the end result will have defects and be left unfinished after it cools down.

Effective way to solve this problem:

  • One way is to update the shape with bigger doors so the resin can move without any problem.
  • The plastic injection speed and weight should be controlled to improve the stream.
  • The shape temperature can be expanded to forestall untimely cooling of the material.

Moreover, within the heating cylinder, a screw mixes the molten material and pushes it to the cylinder's end. The screw controls the speed and pressure of molted material.

Also, the material is allowed then to cool down and set; then the mold is opened or removed the plastic products are ejected automatically out of the machine. Also, the control of thermal processes is vital in the production of high-value plastic products.

 Plastic Molding Company

Plastic Molding Company: Techniques of Molding Processes

There are several methods used to prepare plastic. Below is an overview of the process!

Injection Molding process

It is used to make custom, intricate, plastic parts in various large scale production by injecting plastic material under high pressure into the mold. In addition, the thermostat heats the product faster, cheaper, and form a better product. The mold is allowed to cool, and a plastic part is released when the mold is opened.

Moreover, the sizeable sized machine produces significant parts like dashboards or bumpers, and small machines produce specific parts such as switches, surgical devices, or plastic bottle caps. Products have good dimensional accuracy.

Injection Molding

There are many types of injection molding.

The Rubber Injection Molding.

The rubber is directly vulcanized from the barrel to mold. It happens in intermittent operations, but the molding cycle is short.

Plastic Injection Molding

Molten plastics are used in molds obtained by the cooling process. A particular injection molding machine is used to make plastics.

Mold Injection Molding

In this case, two silicone rubber materials combine into a mixture and produce final parts in one day, such as seals, connectors, cables, medical devices, kitchen devices, and infant products.

The final shape of the product requires no other finishing processes. It is possible to create many details using the Injection molding process. 


Plastic sheets and temperature is used in a mold. There is a variety of thermoforming plastics in colors, thickness, and finishes.

Also, different types of molds are used to create3D products: disposable cups, plates, lids, trays, fridge liner, and auto parts. Tooling cost is low, medium production rate. Thermoplastics can be recycled again and again.

Over molding

In this method, two materials combine to form one object or one part.

There are two types of material used in over-molding. One part is known as a substrate, and the other is over-molding material. Substrate materials are plastic, metal, glass, etc.

Over molding material include rubber and thermoplastics. It eliminates complicated processes and reduces the manufacturing cost, and gives the product a firm grip, specific features. 

  • Casting

A liquid is poured into a specifically designed mold cavity allowed to cool and solidify. The hardened part is known as casting. Thus mold is removed from the casting. Heavy machines and beds, and ships are cast into the required size. Dip molding coating process

It is another plastic manufacturing process where a heated metallic structure in a PVC tank is called plastisol. The plastic is separated from the mold part upon cooling medical.

In addition, Plastic covering makes a protective layer as a finishing and smart look. The plastic coating is done around the mold by the cooling process.

Rotational Molding/Rotomodling Process

The rotational molding process was used in 1950 to make the dolls' heads, and in 1960, s rotational molding allows to make large and hollow parts. So, in-mold liquid or powder resin is kept and rotated in an oven, so even wall plastic is created. There is no wastage of material during this process.

Moreover, this method number of products are made like large hollow simple shape containers, car parts, recycling bin, and slides. Tool costs are less as compared to the other methods of molding like injection and blow molds. 

Blow molding process

In this method, machines heat the plastic and inject air like a balloon to make delicate hollow parts of various sizes that shape the mold's walls. Then it is cooled, and when it is hardened, it is ejected from the mold. Bottles, cans, drums, and tanks are produced by using blow molding processes.

Furthermore, it is cheaper, faster, and economical than the injection molding method but more costly than rotational molding. It has a low production rate.

Plastic Molding Company offers Compression Molding

Heated mold melts the plastic or metals to press to make a specific, unique shape and durability. Also, it is cost-effective and efficient. Cooling and removing the extra parts is done as the final steps.

Final parts are strong and durable and are used in different applications. It is used in automotive parts, fiberglass thermosetting resin, household appliances, hood spoilers, and smaller auto parts.

Extrusion Molding

It is a unique process; a die is used in this method, not a mold. A long, uniform, hollow, solid tubular shape with complex with constant cross-section shape is produced as an end product.

So, when the extrusion cools, it is removed from the machine. PVC piping, tubes, straw, dependable rods, wire, cables, strips window frames, hoses, plastic gutters, and straws are included.

Thus, the cost of extrusion molding is low, but the production rate is high because of the simplicity of die and machine.

Spin trimming

The machine trims around the domes or neck of bottles made by blow molding at a higher and efficient speed. There is no leakage from the bottles.

Vacuum molding

Plastic sheets are heated on to a single surface. Original silicone made a mold by a vacuum. This process takes a few days to become a functional prototype. In addition, Plastic sheets are prepared with high-quality fine details. This process is costly for a number of parts.

Compression molding

Preheated material is used in the mold cavity. Moreover, the mold is closed with a plug and then compressed the material. It is used to make flat or curved parts. There is little waste, and it cost low.

The process of molding plastic originated back in the 19th century. The method was invented in the year 1872 when two manufacturers Isaiah and John Hyatt invented the molding machine to mold plastic.

Plastic Injection Molding Factory

The molded plastic to manufacture daily used items like combs, buttons, etc. Thus, this first leap proved to a breaking point in the plastic manufacturing industry.

How Contemporary Plastic Injection Molding Factory revolutionizing the modern world?

As in today, we cannot think of the world we are in without the invention and utility of modern computers and technology. Similarly, these technological devices would not even exist without the presence of such an advanced, high quality, reliable, and flexible modern plastic molding industry.

Modern plastic injection molding factory paved ways for modern technological devices to step into the real world.

Utility and Advantages

Modern Plastic industry using an injection model is coming up in each passing day with economic, reliable, complex, and quality plastic models and solutions.

These solutions are in daily use for multiple ranges of applications. The molded plastic parts are widely used in every industry because of its durable and reliable nature in terms of corrosion and erosion.

Accuracy in Complex Injection Molding:

The modern plastic injection molding factory uses a variety of methods and modern techniques of injecting plastic into complex and highly detailed molds.

It creates a complex plastics design with several details and features. The basic working model of the injection molds uses high pressure as its main subject. This, thus, exposes plastic to hard press, which helps in getting the complex and desires shapes/designs in real-time.

As opposed to the conventional molding method, the modern molding industry makes it easier for the plastic to get in shape by creating intricate designs and shapes.

This method in plastic products comes up with such precision that it is impossible to think of in using the conventional methods of plastic molding.

The level of precision in the plastic injection molding factory is extremely accurate. A single manufacturing unit can easily fabricate a plastic model of any type to a level of 0.001 inches.

This process is known as precision molding. The process is completely automated. Therefore, it remains inexpensive for the manufacturers even if they are to develop the most complex designs. Yet, this is the most sophisticated method of molding complex and reliable designs in the market.

The process of precision molding differs largely from the conventional molding machines. This is because conventional molding machines lack such detailed precision, quality, and durability in design. Whilst, precision molding includes complex geometric in manufacturing the complex, precise plastic molds.

High-Quality in Injection Molding:

The nature and use of plastic have changed over time. The plastic injection molding factory has revolutionized the plastic products that contain high quality, durability, and precision as the basic elements in all items.

The conventional methods of manufacturing produce hard and heavy plastic products. Whereas, the modern molding techniques and technology using injection have enabled the industry to design lightweight products. But these are stringent materials that last even in the most rugged weather having extremely hot /cold conditions.

The modern injection methods are making it possible for the manufacturers to add the fillers in injection molds. These fillers are missing in the conventional methods of plastic molding. These fillers like calcium, silica, clay, etc., thus add quality and variety of strength to plastic depending upon the usage.

The strength and stiffness of the plastic material increase using fillers. However, it also helps in decreasing the overall density of the plastic material, thereby reducing the weight and bulk of the final product. Lightweight and high strength are what injection molding is all about.

Furthermore, manufacturers use fillers in order to increase the heat resistance of products. Small plastic parts used in various industries like auto manufacturing or kitchen products need durability and flexibility.

This is because such products usually face high/low temperature and pressure. Manufacturers use Nylon (Polyamide) for quick-release buckles and passenger seats in public transport. For refrigerators, manufacturers use Acrylics as refrigerators store food at low temperatures, and for knife handles, they use polyoxymethylene (POM). 

Whereas, the traditional method of molding plastic using lacks these characteristics and has its own limitations both in production and designing. The modern methods of injection molding are versatile and are also equipped with bulk production.

Plastic Injection Molding Factory

Cost-effectiveness and Less-Wastage in Injection Molding:

Plastic injection molding factory, considering the prevailing environmental degradation, is one of the sustainable manufacturing industries. As known, plastic is one of the non-biodegradable materials which is causing and destroying the ecological setup of the global world.

The conventional method of plastic molding involves the cutting of large plastic pieces into smaller ones leaving a large amount of plastic solid waste material.

In addition, injection molding is an automated process that involves a minimal amount of human labour. The invention of modern machinery to perform molding using computer-operated machines and robots has revolutionized the plastic world. This thus makes injection molding a cost-effective process.

Unlike the conventional method, which involves human labour, the injection method reduces the labour incentive. The injection molding units use software and technologies like CAD and CAM. The ability of the system to design precise and accurate design in one go.

This makes the product ideal, thereby reducing the chances of recreation. It also reduces the cost by 25 times as compared to the conventional method.

6 Benefits That Would Make You Want to Automate Your Plastic Molding Process Today!

Automation in Plastic molding is experiencing a rising trend. Automated plastic molding machines made up 32% of all the machines sold in 2019, which has risen from 18% in 2010. Many ambitious molders opt for automated plastic-molding machines for the efficiency that the robots confer upon this process.

What is Plastic Molding?

If you are here looking for benefits of automation in plastic molding, chances are you already know what plastic-molding is. But still, let us brush up your knowledge a bit, and then we'll get to the pros in a moment.

Plastic moulding is a process of converting molten plastics into well-defined shapes and sizes. The injection molding machine melts granular plastics first. And then, it injects the molten polymer into a mold of any shape and size.


After being injected into the mold, the machine applies pressure to the molten plastic and cools. This way, the plastic solidifies and takes the shape of the cavity inside the mold. The mold then opens up, drops the plastic piece, and closes for the next 'shot,' and completes one cycle of the process.

A typical production cycle can take anywhere from 2 seconds to up to 120 seconds to complete.

What is Automation in Plastic Molding?

Automation of a process translates into the integration of innovative technology and smart robotics into any process. An automated process offers increased productivity, capacity, and efficiency compared to a non-automated, fully manual process.

The world is getting more involved in developing ultra-modern technology. People want technology to aid humans in every field and reap smart and efficient robots' benefits. The injection molding industry keeps up with the fast-paced world and takes immense interest in the automation of their processes.

Automation of the plastic moulding process gives the molders an edge over their competitors who are yet to integrate automation with their process. Now, to efficiently compete with their 'automated' peers, more and more molders are handing their processes over to the robots.

How is Automation Enhancing the Plastic Molding Process?

Automation is effectively augmenting the plastic-molding process by decreasing cycle times and ensuring consistency in product quality. Here are just a few of the many advantages that justify why plastic moulding automation is imperative in today's world.

1. Increases Productivity

Employing robots to perform specific tasks in your injection molding process will lead to increased productivity. Unlike humans, robots never sleep. They never take breaks. Moreover, they don't need to go home after their shift is over. Hence, an automized plastic-molding process can stay in operation throughout the day, seven days a week.

Therefore, by automizing the molding process, you can keep manufacturing and selling products without frequent breaks and enjoy increased revenue.


2. Increases Production Capacity

With increased productivity comes increased production capacity. Automated machines are capable of producing plastic-molded parts at a much higher rate than manual machines can. The increase in production rate is because automated machines work faster, without a pause. Thus, they are often capable of producing thousands of perfectly molded plastic pieces in just one day!

3. Ensures Consistency in Product Quality and Specifications

Humans tend to make mistakes. It is normal. But a mistake is not just a mistake in the plastic moulding industry. It is a loss—a loss of time, effort, and of course, money. In manual molding processes, chances of the product specifications deviating from customer-defined parameters are high, which leads to losses in terms of lead time and raw material.

However, once programmed appropriately, machines can roll out plastic parts in every cycle that match exactly with the specifications fed to the machine—thus adding consistency to the molding process's throughput.

4. Automation Minimizes Cost

The common idea associated with plastic moulding automation is that it is bound to cost you an arm and a leg to get robots to do the tasks that human workers are already doing.

However, contrary to this belief, integrating automated machines in your process saves you a lot of money. How? Firstly, a single machine takes the place of multiple workers, which means you save on the cost that you may spend on these workers' salaries and other incentives.

Moreover, an automated plastic molding process produces fewer defective parts, which means you save money on the raw material. Furthermore, since automizing optimizes the entire process, this means robots will yield a significant return on investment very quickly.

5. Optimizes the Process.

Automating your plastic molding process is a sure-fire way to optimize the entire process. Automated plastic moulding machines produce high-quality parts in every cycle, yielding fewer plastic parts to discard. Consistent-quality production saves a lot of raw material that would've otherwise been wasted if the produced part was defected and rejected.

Moreover, automizing the plastic moulding process saves up a lot of labor as machines clean any leftover plastic that tends to solidify in the mold. They also load molded plastic parts on the conveyers. Thus, they eliminate the need for humans to do such primitive tasks and allow you to assign your human workforce tasks out of the machines' performance scope.

6. Lowers the Risk of Workplace Injuries

An industry such as the plastic molding industry that involves a lot of heat in the form of molten plastic and heated plastic parts runs a high risk of worker injury.

Moreover, the plastic molding process requires repetitive tasks such as removing molded-plastic parts and loading them on a conveyor. Then packing them and preparing them for shipping. All of these tasks are not only tedious but monotonous and excruciatingly exhaustive. Thus, they may lead to elevated-stress injuries among the workers.

Therefore, by employing automated machines to do all the highly repetitive tasks, you can save your workers from work-related injuries and utilize their capabilities in a more productive and less physically exhausting area, such as operating the machines or programming the robots.


Final Thought

Most people often criticize robots and automated machines for stealing human jobs. However, the reality lies at the opposite end of this spectrum. An automated plastic moulding process does not replace humans with robots, but they create better higher-paying jobs.

These robots control the potentially harmful aspects of the processes. And allow humans to control and monitor the process while staying far from their life-threatening aspects.

Moreover, they prevent exhaustion and stress injuries among workers by performing repetitive tasks that are the trademark of the plastic moulding industry efficiently without getting tired.

Thus, the automation of plastic moulding has innumerable virtues not only for the plastic molding owners but for the workers as well. Automated machines reduce human downtime, lead time, cycle time and increase profits, all the while ensuring proper health and safety of the workers

⊙Reporter Xia Zihang ○ Editor Xu Rui

Just as the National People's Congress deputy, Chu Tian Technology Chairman Tang Yue foresaw a few years ago, where the pharmaceutical industry is fully entering the "pharmaceutical industry 4.0 era." In his view, it is very important to deepen the public health reform of the disease control system, establish a modern disease control management system, and accelerate the development of biopharmaceutical equipment.

Develop pharmaceutical equipment to help prevent and control COVID-19

"The new coronavirus, which has a high infection rate, a long incubation period, and multiple transmission routes, poses a huge challenge to the world's pharmaceutical industry." Tang Yue said.

At this year's two national conferences, Tang Yue put forward "suggestions on accelerating the development of biopharmaceutical equipment and improving local disease prevention and control capabilities." "Biopharmaceuticals are an important part of the national economy and have a closer relationship with people's livelihood. The main popular figure Tang Yue said that at present, the gap between the level of domestic biotechnology and biopharmaceutical core equipment is far from the world's advanced level.

In response to this problem, Tang Yue suggested that the state should introduce supporting policies to encourage the development of biopharmaceutical equipment, focusing on enhancing the emergency production capacity of epidemic prevention and control products; further promoting traditional Chinese medicine, accelerating the research level of Chinese medicine preparation equipment, and promoting Chinese medicine preparation equipment Quickly realize automation, digitalization, and intelligent upgrades; at the same time, encourage school-enterprise cooperation to achieve integrated development of production, education, and research, make full use of talents from universities, research institutes, R&D, technological advantages, and enterprise platforms and market advantages, and actively promote R&D and production, Close cooperation in sales.

The arrival of "the era of pharmaceutical industry 4.0"

A few years ago, Tang Yue said to the Shanghai Securities Journal reporter that in the future, the medical equipment industry will usher in a continuous huge dividend in the world, that is, "pharmaceutical industry 4.0" and the upgrading of pharmaceutical intelligent manufacturing. The direction of development will be obvious after 5 years, and there will be changes in the outline after 10 years. In Tang Yue's view, "Pharmaceutical Industry 4.0" can greatly reduce the hidden dangers of medical safety.

According to reports, pharmaceutical intelligent manufacturing and "Pharmaceutical Industry 4.0" can realize real-time, online, full-range, all-round automatic monitoring of pharmaceutical manufacturing and circulation consumption, and automatically generate data (and cannot be tampered with), automatically read data, Automatically store data to the cloud, zero delays, no dead ends, no blind spots. According to the authorization of the law, regulatory authorities, drug producers, and consumers can consult and retrieve relevant data.

Tang Yue believes that in the future, high-end pharmaceutical equipment, "pharmaceutical industry 4.0" and intelligent manufacturing will be regarded as "rigid demand" for pharmaceutical factories. Based on long-term foresight, Chutian Technology has successfully developed some intelligent pharmaceutical production robots and related production lines using automation and information technology and is transforming into an EPC service provider that builds a "pharmaceutical industry 4.0" smart factory overall solution.

The 2019 annual report shows that Chutian Technology's industrial layout has begun to show its advantages. The traditional advantage of Chutian Technology lies in the liquid pharmaceutical equipment, and its production and sales are at the forefront of the industry; Chutian Huatong, a wholly-owned subsidiary, is a professional research and development of pure steam generator, multi-effect distilled water machine, purified water preparation system, and other products. Manufactured pharmaceutical equipment manufacturing enterprise; Military Pharmaceutical Engineering Design Service of Sichuan Pharmaceutical Design Institute, a wholly-owned subsidiary; Chutian Robot, the holding subsidiary's main products are medical and medical robots; in 2019, Chutian Technology has added an intelligent Chinese medicine machinery product line.

Chutian Technology recently stated on the interactive platform that Sichuan Pharmaceutical Design Institute, a wholly-owned subsidiary of the company, has the design and construction capabilities of the P3 Biosafety Laboratory. During the epidemic prevention and control period, Sichuan Medical Design Institute undertook the design of the high-level biosecurity laboratory (P3) of the Eighth People's Hospital of Guangzhou City, which was highly recognized by hospital experts.

Currently, Chutian Technology is planning a follow-up merger and acquisition of ROMACO. ROMACO is currently the seventh-largest medical equipment company in the world and a senior solid preparation packaging manufacturer. Its products have entered more than 100 countries and regions in the world.

In the Internet age, how does the medical

In the Internet age, how does the medical "couple shop" live?

Jul 02, 2020
By hqt

"At the time I was being consulted and my wife was dispensing medicine. When I am the busiest, I will call my cousin to take care of them. Many people in the village come here to see a doctor. "
Speaking of which, Dr. Li's hand in the clinic shook slightly. But the white coat and hair still maintain the rigor of the past, meticulous.

The plaque after the unified reconstruction of the streets has faded, and the outer walls are covered with medical notices and aftertastes of Chinese medicine and disinfection water. All the decorations are the same as the older Dr. Li and his wife: traditional, stubborn, and deadly.

This is a typical small self-employed clinic with a couple of "1 doctor + 1 pharmacist", which is what most medical "couple shops" look like.

"Now that the nurse has resigned, you must clean and disinfect yourself. You can get full every month." Dr. Li took off his glasses, drank strong tea, and took a long breath.

In the half-day of the interview, there was indeed only one guest in the pharmacy in front of us to buy Band-Aid. In addition, most of the time, Dr. Li and his wife Jiang Yaoji are studying how to use the latest online purchase software. As far as the two old doctors are concerned, the learning process is not simple. Finally, they still had to embarrassingly choose to call the service staff of the original pharmaceutical company.

However, once started, the sales staff will follow the software introduction and "enthusiastically" recommend Dr. Li to participate in the clinic upgrade project, and encourage: "Several clinics in your area have joined, and your traditional clinic is outdated. No, It doesn’t matter, we can come over to help you personally."


In response, Dr. Li refused without thinking. He hung up the phone, turned back to "the theory of relativity intelligence," and asked: "I don't understand. In the hospital, our old doctors are also somewhat famous, and the registration fee is a few yuan more expensive. Now that the Internet is coming, should we damn it? "

"Dare you dare to see a doctor on the Internet?"

Before opening his own clinic, Dr. Li was an orthodox medical student of that era and the successor dean of a township hospital.

“After I took office in 2005, the hospital was sold. I couldn’t do anything except seeing a doctor, so I rented a house and opened a clinic. I was in charge of injections, and my wife became a pharmacist. Whenever It is very busy at noon, often eating cold meals or not eating at all. There is no way, once the patient enters the door, we must receive him immediately."

But with this desperate hard work and excellent medical skills, this small clinic of only a few tens of square meters became famous locally in only one year. In 2010, Dr. Li simply bought a facade and expanded the clinic on "his own place".

"He looks fierce. In fact, he has always been an idealist. Those who do not need injections only need oral medicine. In the past SARS, this medicine was very expensive. If you give him more money, he still gets angry. There are six to seven clinics on this street, familiar (people) come often (Dr. Li's clinic), and people who often come from nearby cities..." Li's neighbor quietly asked "Intelligent Relativity".

However, when a company is doing too well, the capital that exudes "fishy smell" will always squeeze into this field and start to compete. In the eyes of capitalists, even life-saving medical treatment is nothing but "business."

Data from the China Health Statistics Yearbook show that between 2010 and 2017, the number of clinics in non-public grassroots medical and health institutions increased from 173,434 to 211,572, an increase of about 22%. The proportion of the total number of institutions rose from 41% to 54%.

Also at that time, Dr. Li and his wife felt that the (clinic) became more and more difficult to do.

Especially in June 2015, "Several Policies and Measures for Promoting the Rapid Development of Social Medical Treatment" (hereinafter referred to as "Measures") was issued. The state proposed to insist on opening medical treatment and implemented "non-prohibited entry" for social capital After the gradual progress, the feeling becomes more obvious.

The "solution" divides qualified social medical institutions into the scope of medical insurance fixed points and implements the same policies as public medical institutions. This solves the medical insurance problem, and also allows the Internet operation model to explode rapidly after the capital officially enters the market, making medical "self-employed" even more difficult to chase.
