Your Comprehensive Guide on Plastic Corner Molding in China
Sharp edges no doubt look great. But, they can be huge trouble when molding plastic parts. They increase stress concentration which can lead to part failure. These sharp edges most commonly occur in non-obvious places such as a strengthening rib. For this reason, plastic corner molding in China tries to avoid it at all costs. Want to learn more about the design considerations for injection molding? This guide will tell you everything that you need to know. Keep reading!
Design Considerations for Plastic Corner Molding in China
There is a huge risk of error while designing corners for plastic corner molding in China. These issues can range from small surface faults to some grave problems that can impact the performance and the functionality of the product. These errors can occur due to many problems such as the process of the molding, the material used, and the tooling design.
We have listed some obvious mistakes that make occur while molding the edges of a plastic product below. Let’s take a look at them.
1. Flow Lines
Flow lines look like a curvy pattern and are of a different color than the rest of the area. These lines occur due to difference in the cooling speed of the material when it flows in multiple directions in the mold. They most commonly appear on the narrower sections of the molded component.
Sometimes, they are even visible as ring-shaped bands on the surface of the product near the entry points. Although these lines do not impact the integrity of the product, they can be unpleasing to the eyes. Moreover, the consumer may even reject the product if they found flow lines on it.
Warping is another common defect that occurs during plastic corner molding in China. It is a sort of deformation that appears when different parts of molded products are shrunk unevenly. When the shrinkage is uneven, it puts stress on different parts of the product. As a result, bending of the finished part takes place.
It occurs when the cooling process takes place too quickly. Furthermore, the excessive temperature can sometimes make the problem worse. Another reason for warping can be the mold design. When the walls of the design are of uneven thickness, this may also result in warping.
3. Burn Marks
These marks look like rust-colored or black discoloration and may appear on the corner or the surface of the molded plastic part. Generally, these marks do not affect the integrity of the product unless the product burns so much that it is degraded.
So, why do these marks occur on plastic products? Well, the most common reason that they appear is because of the trapped air, overheating, and resin during the mold cavity. So, if you want to avoid these burn marks, you must lower the melting temperature and reduce the injection speed.
4. Sink Marks
For those of you who don’t know, sink marks are depressions that appear on the surface of the product that is extremely flat and smooth. These marks appear in the plastic product when its inner molded part shrinks.
When the inner part shrinks, it pulls the material from the edges inward. So, what causes the depression in the surface that was smooth and flat before? The sink marks appear when the molded material takes a lot of time to cool down.
This results in shrinkage which then pulls the material from the edges inwards before it has the chance of cooling down. As a result, depressions in the form of sink marks occur.
5. Air Pockets
Air pockets are air bubbles that are trapped in a finished product that is molded. Although it is considered a small defect by the quality control professionals, the large and numerous voids have the power of weakening the plastic product.
That’s because the air is below the surface of the product where the molded material should have been. Unsuitable molding pressure is one of the most common causes of air pockets or vacuum voids. The inadequate molding pressure forces the air that is trapped in the product from the mold cavity. As a result, air pockets may occur in the edges of the plastic molded product.
Jetting is a kind of a corner molding defect that appears when a jet of molten material is injected into the mold cavity. The major cause of jetting is all the extra injection pressure.
When the material solidifies before the cavity is filled, it results in jetting. It does not only look unpleasing to the eyes but it can result in the weakness of the product as well. Therefore, it should be avoided at all costs. You can reduce the injection pressure and increase the mold and material temperature to avoid jetting.
7. Weld Lines
Weld lines are another common molding mistake that appears in the products of plastic corner molding in China. These lines appear on the surface of the edges where the molten material has converged after splitting into different directions in the mold.
This results in hair-like weld lines. These lines have the capability of weakening the strength of the product. Therefore, they must not be taken lightly and should be avoided at all costs.
So, how can you avoid weld lines in your plastic molded products? Well, the answer is extremely simple. All you need to do is increase the temperature of the material during molding and raise the speed and the pressure of the injection.
Although sharp edges look pleasing to the eyes, they are not suitable for plastic corner molding. They can result in the weakening of the product. For this reason, they must be avoided at all costs.
We hope the above mentioned defects will help you identifying the molding defects when you see one so that you can avoid them later. For more information, reach out to us and we will be happy to assist you.

Some Common Designing Defects Incurred By a Plastic Injection Molding Injection Factory
Sometimes, a defect may occur in the design of the final product of the plastic molding. The plastic injection molding factory incurs these defects due to several reasons. Let’s check out some common designing defects below.
When a certain part of the plastic product cools down faster than the other parts, it starts shrinking. The shrinking of that specific part can result in permanent bending of the object. That’s due to the internal stress that the product faces. This is what warping is called. The parts of the plastic product that have thick walls than other parts are more prone to warping.
2. Sink Marks
When the inside of any part of the plastic product solidifies quicker than its surface, a small sink mark may appear in that specific part. This is why it is known as a sink mark. The parts of the plastic product that have a higher risk of sinking are the parts that have poorly designed ribs or have thick walls.
3. Drag Marks
Another common defect in the design of a plastic product manufactured by a plastic injection molding factory is known as drag marks. It occurs due to the shrinking of the plastic. That’s because when the plastic sinks, it applies pressure on the mold.
As a result, the walls of those specific parts will slide during the ejection process. Not only this, but the walls will also scrape against the mold. This may result in drag marks. The parts that are more prone to drag marks are the parts that have vertical walls.
4. Knit Lines
When two flows of a plastic product meet, you may notice it developing hair-like discolorations. These hair-like discolorations are extremely small. That’s called knit lines. The parts of the product that are more prone to knit lines are the ones that have holes in them. Knit lines not only ruin the aesthetics of the product, but it makes the plastic product weaker as well.
5. Short Shots
Short shots may occur in plastic products that have extremely thin walls. Sometimes, the air that is trapped in the mold can block the flow of the plastic during the injection molding process. This might result in the product coming out as incomplete. For this reason, it is extremely important to design products that have a flawless design. When the design is good, it will improve the flow of the melted plastic.
Plastic injection molding is extremely popular among the manufacturing industries these days. That’s due to the many benefits offered by this process. For this reason, many plastic injection molding factories are using it as well.
But, some common design defects may incur if you do not observe the process closely. This is why you must observe the entire process extremely carefully. For more information, contact us now!

Plastic Jello Molds --- Buying Guide
Plastic jello molds are molded bodies comprising gelatin. Gelatin is already employed widely in industries to prepare medical capsules, adhesives, and photographic films.
However, the brittle nature and sensitivity of moisture and heat of solid, un-plasticized gelatin have made its use unfeasible as a construction material. However, the resistance to moisture and heat improves by tanning it. For example, you can mix tannic acid with gelatin.
You can also do it by reacting gelatin with phenolic or/and aldehydic compounds or chromium salts. As a result of this chemical modification, gelatin becomes a horny substance. In this article, we will discuss the process behind plastic jello molds. We will share the complete recipe to make the process of making jello molds look straightforward.
The Method behind Plastic Jello Molds
Today, plastic molds are used to manufacture various shaped objects. The material proves inexpensive and readily available for different industries, including construction.
A molded material made at a temperature of 100-degree centigrade to below 125-degree centigrade that is still water-soluble remains edible. The treatment of gelatin depends on the invention with pressure and heat. Therefore, there will be no contaminants that make the food unsuitable for eating. Thus, it would be a perfect edible construction substance suitable to be used within space vehicles.
Additionally, plastic jello molds also help deploy additional scientific and supplied equipment for formerly landed astronauts in unmanned vehicles with molded gelatin parts and carrying gelatin molded goods in containers. These containers and components can be the ideal approach for serving food.
You can also mix other nutrients with the gelatin before molding to improve the food quality of containers and vehicles made from there. For example, there can be incorporated casein, starches, and sugars, etc., either in textile or fiber form or as fillers.

They are most commonly seen in electronic devices, types of machinery, constructive tools, toys, and packaging equipment. The results of plastic molding home depot products are exceptional which is why they are easy to use and achievable through injection molding. The following is an in-depth guide for the process of plastic molding home depot.
The Features of PVC Plastic Molding Home Depot
PVC is an ideal material for making plastic molding at home depot. The reason for it being an attractive choice for making plastic injection molding products is due to its poor thermal conductivity. Although it is a poor conductor of heat, this is the most beneficial quality when manufacturing products through injection molding.
PVC can damage and can incline towards flaws. Hence, when using it for plastic molding at home depot, the PVC can pose some threats in manufacturing. It is better to add a plasticizer to strengthen the PVC and help in improving its fluidness. Moreover, it is important to add further additives to improve the core strength, electric lining, and resistance to substance usage during injection molding.
Although it is domineering how the market deluges with plastic molding home depot, you can even broaden the spectrum by looking into similar manufacturers that deal in the same quality products. One such manufacturing site is https://www.sz-changhong.com. They are a viable choice for many plastic injection molded products and parts.
The Design of PVC Plastic Molding Home Depot
It is always better to come up with a design that is compatible with the functionalities of the molded object. In this case, the input material is PVC plastic hence there should be a minimization on the gate length. It is only possible through a cross-sectional design that does not exceed the diameter of 6 millimeters. In addition to this, the design must be in a conical shape that has a conical angle not more than 5 degrees.
It is important to follow the settings defined for using the PVC injection molding process if you want to get a good turnout. Using a cooling cartridge is also useful in preventing the melted PVC from entering the hollow cavities of the design mold. If not thought over properly, it can damage the exterior finishing and the longevity of the product by compromising its strength.
It is also useful here to mention the design of the drafting angle. It must fall between 0.5 to 10 degrees at all costs. Otherwise, there won’t be enough expulsion mechanics available for the process to vent out excess heat.
The Steps for PVC Plastic Molding Home Depot
Generally, PVC plastic is sensitive to heat. This way it can decompose if PVC has excessive exposure to excess heat and trimming. Since PVC is such a delicate material, one negative impact can act as a catalyst and destroy the whole material. In some cases, it can even generate high-level damage that is irreversible, like creating indentations, chemically peeling, and cause rust on the surface.
This is why when performing plastic injection molding on PVC plastic; you have to follow the instructions to the dot. The most commonly used length for screwing instructs a diameter setting of 18 to 24:1. Moreover, the tip should angle at more than 25 degrees and less than 30 degrees. Plus, the stainless steel screw is important in this case.
The plastic molding technique is not very antique, hence there is always something new to learn when using new and unusual materials. Each material can react differently under pressure-induced during plastic injection molding. So, it is better to pick up tips and tricks along the way that can help in understanding the working of similar materials.
It can even help in creating generic values, instructions, and understandings that can act as a guiding light for future use. The following are a few settings to feed in the plastic injection molding processing for PVC plastic.
Settings for PVC Plastic Molding Home Depot
There are some intended settings and instructions that sit suitably with PVC injection molded products. It even involves very specific settings for some parts. The screw cushion must stay between 2-3 millimeters. It can even increase for large-scale machinery. As for the injection volume, it must not surpass 180 seconds.
There are even proper guidelines for setting the barrel temperature. These changes depend on the positioning of the nozzle and the part where the barrel is pointing. This also requires timing. In most cases, the timing does not exceed more than 5 minutes; of course, there can be exceptions to this rule depending on the material change.
In general terms, the injection molding speed must be moderate. Moreover, the speed should be consistent in order to prevent the material from degrading. The backing pressure is also a considerable point here. So is the mixing ratio of different materials, and even the materials that come from the same family. By using these guidelines, injection molding becomes effective in producing PVC products with longevity and durability.
You can easily find high-quality PVC plastic injection molded products that enable durable and long-lasting usage.
One such website that advertises such products is SZ-Changhong. It is important for injection molding manufacturers to understand the underlying need for proper guidelines in molding different materials. Unlike other industrial productions, injection molding needs to follow very specific instructions to produce a quality outcome. It is even possible to reduce time and cost simultaneously using these techniques intelligently.
