7 Outrageous Ideas of Diy Plastic Injection Molding Machine

What are the plastic molding techniques?

The molding of plastic materials is the set of all those technologies which, thanks to the use of a diy plastic injection molding machine. It allows the production of components in polymeric material. Over the years and with the development of increasingly advanced technologies. The types of molding have differentiated according to the:

  • Material to process
  • The shapes to obtain
  • The physical characterization that the final product must assume

Diy-Plastic-Injection-Molding-Machine

The techniques that are most widespread today are the following:

Compression molding: rubber vulcanization process

It essentially consists of the rubber vulcanization process. The mold that gives it its final shape is in steel or aluminum. Depending on the shape of the product to produce. It is easy to make up of several parts in order to facilitate its removal when the molding completes.

The diy plastic injection molding machine for this type of molding is a press on which the mold fix to the working surface.

The working pressure varies from a few tens to about 850 tons. The worktop thermally control: in relation to the elastomer being processed. The electrically heated surface works at a temperature between 140 and 180 degrees. This type of molding is very flexible because it allows inserts of various kinds to incorporate into the product.

Polymer injection molding: an industrial process

It is an industrial process in which the plastic material heats and melts under high pressure into a closed mold. It will then open when the material has solidified.

Both the injection pressures and the temperatures of the material in diy plastic injection molding machine being processed are very high. This to allow easier sliding of the plastic material in the ducts of the machinery and in the mold itself. The machinery dedicated to this process is the so-called injection press which comes up of two main parts: the injection group and the closing group.

The first has the function of bringing the material to the melting temperature and, once plasticized, of pushing it into the mold. The closing unit, with hydraulic or mechanical operation, ensures the clamping of the mold.

Diy plastic injection molding machine with reaction

Injection and reaction molding, also known as RIM, Reaction Injection Molding. It is a process that uses polyurethane compounds for the production of large-sized products. Originally, its development dates back to the 1950s, it was mainly common in the automotive industry.

 This technique involves the use of two components in the liquid state before transfer into the mold: the Iso fraction, which contains isocyanates, and the Poli fraction, which contains hydroxyls.

The dedicated machinery comes with an aluminum mold inside which the polymerization and solidification of the material takes place. The modern technology that the diy plastic injection molding machine come with allows the creation of objects of all sizes.

Thermoforming: use of vacuum or pressure plates or films

This molding technique starts from vacuum or pressure plates or films. In the first case, the preheated sheet adheres to the mold by suction, assuming all its surface sensuosities.

In the second case, the sheet rests on the sheet due to the pressure applied with air which also speeds up its cooling. Thermoforming is particularly suitable. If the quantity of pieces to produce is large and production times are short and even if the batches to produce are different.

Machine is very versatile and flexible

By its very nature, a diy plastic injection molding machine is very versatile and guarantees a very high production flexibility especially if the thickness of the pieces is very thin. Generally, this machine is common for food-grade trays, blisters, Abs trays but also for internal cases of household appliances and finishes in the automotive sector such as panels and coatings.

Blow molding for a hollow shape

Blow molding is a technique common to give the plastic material a hollow shape. The most classic examples of this variant of plastic molding are produced as bottles, flasks and containers with very small opening compared to the other sizes.

Blow molding obtains with a jet of powerful compressed air blown into a preform in such a way that the worked object inflates and takes the shape of the mold that contains it. Once cooled, the object extracts from the mold and the processing complete. Machines for this type of molding usually equips with an extruder to make the preform.

Diy plastic injection molding machine for important dimensions

Rotational molding or rotational molding, is the molding technique common for the production of hollow products of important dimensions. The process consists of introducing plastic powder into a hollow mold which is then rotated on two axes.

At the same time, the mold heats to melt the material and make it adhere evenly to the walls. The mold is usually built with a composite material such as aluminum.

As in the other cases, cooling and extraction of the finished product, which is often manual, follow. The typical products of roto moldings are vases, bins, boats, furniture and toys.

Diy plastic injection molding machine for molding plastic materials:

Plastic material molding machines are sophisticated and highly technological equipment. Buying new ones often coincides with an excessively demanding economic effort for every type of company, whether it is opening or relaunching. Second hand is a viable solution, as long as it is efficient and guaranteed machinery.

In these cases, the unknowns are numerous and critical, difficult to dispel with only a basic competence of the subject. Most of the time it's like buying a pig in a poke and the game isn't worth the candle. The savings on the purchase can cause unpleasant inconveniences even in the short term.

When buying common machinery becomes a problem

How Aluminum Soft Plastic Lure Molds Can Increase Your Profit!

Introduction of aluminum plastic lure molds

The technique of the aluminum soft plastic lure molds allows creating molds that reproduce the complete model in all its parts, in the round. Otherwise, it is impossible to extract from simple single-valve molds.

In the construction of a mold, the original model to reproduce (master) can be an already existing figure, or a personal creation of the model maker. To make a model, various materials can be common, such as:

  • Wood
  • Plastic
  • Plaster
  • Clay
  • Wax etc.

Aluminum-Soft-Plastic-Lure-Molds

Create the desired shape in a short time

Plasticine is undoubtedly the most suitable material for aluminum soft plastic lure molds. It offers the greatest creative freedom and allows you to create the desired shape in a short time.

Non-porous surfaces (e.g. metal, plastic) do not require the preliminary use of release agents. On porous ones (wood, concrete, plaster, clay, etc.)

It is advisable to apply an insulating layer with shellac paint

It is in order to prevent the silicone rubber, fluid before hardening, from penetrating into the pores making subsequent demolding operations more difficult.

Moreover, it is very important that the separators are very fluid. They are applied (by spray or brush) in a very thin layer. It is to interfere with the precision of the details to aluminum plastic lure molds.

Once the volatile part contained in the separator has evaporated. It is advisable to subsequently apply a very thin layer of waxy release agent.

Get aluminum soft plastic lure molds

Once you have the original model to reproduce, the first thing to do is to get a pourable silicone rubber for molds. This rubber consists of two parts, a silicone compound plus a catalyst. You also need plasticine and wooden tablets of various sizes.

Preparation of the mold

On a wooden base, aided by plasticine, form a kind of box of such size as to comfortably contain the model to reproduce. In our example we will proceed to the reproduction of a lead soldier. Make sure that the sides of the wooden boards fit together perfectly and leave no space.

Aluminum soft plastic lure molds: fill the structure with plasticine

We will fill this structure with other plasticine until we reach half the height of the box and then we will insert, by pressing lightly but firmly, our master. It must insert into the plasticine up to about half of its height.

If it is our intention to use a polyaddition silicone rubber for the production of the bivalve cast. It will be necessary to use plasticine without sulfur. This does not create phenomena of catalysis inhibition.

Molds 2: cover the lower half

Alternatively, always place the aluminum soft plastic lure molds in the same box and pour some melted wax to cover the lower half. In this case it is advisable to wrap the lower part of the model with aluminum foil to prevent the wax from adhering.

With this system the division of the mold is in a straight line. With the plasticine method a more complex division plane is easy to obtain. It is able to exactly follow the morphology of the object to be reproduced.

Common method to align the two halves of the mold

Adjust the surface of the plasticine or wax around the aluminum soft plastic lure molds and form four hollows on the four sides of the modeling clay. This will be common to align the two halves of the mold.

At this point we will have to decide whether to proceed with the preparation of the sprue and the air escape routes at this stage, or whether to wait until the realization of the two silicone rubber molds finishes.

In the first case, to create the casting duct, through which the material will pours into the mold, a sort of plasticine funnel prepares and two equal parts divides. A half funnel attaches to the plasticine. This divides surface, with the thinnest part connected to the aluminum soft plastic lure molds at a predetermined point and the flaring outwards.

This adheres to the edge of the containment box. The other half of the funnel will then be common to complete the conduit in the second valve.

Aluminum-Soft-Plastic-Lure-Molds-2022

Prepare a vent channel for the air

It is also necessary to prepare a vent channel for the air near the pouring one. For this purpose, you can use a drink straw half-drowned in plasticine. This connects the model to the edge of the wooden box. Any additional vent channels require at all aluminum soft plastic lure molds highlights to prevent air pockets from forming when the material pours into the mold.

The sprue must be only one, wide enough.

It is a basic example of what we will have to do as we should adapt the work to each subject taking into account. It is to ensure that the material with which to fill the mold arrives in each corner before solidify. The air escape channels must be sufficient in order not to allow air bubbles to remain in the recesses that the lead will have to fill.

Aluminum soft plastic lure molds: construction of the first valve of the mold

At this point the model is ready for the construction of the first valve of the mold, but first we will have to proceed with the preparation of the silicone rubber

Preparation of the silicone rubber

Before talking about their preparation, let's see what silicone rubbers are.

What they are Silicone rubbers are liquid or paste products that are cold vulcanized by means of a catalyst, from which stable compounds with high elasticity are obtained.

Thanks to their peculiar characteristics, silicone rubbers offer great advantages in the construction of aluminum soft plastic lure molds. It is good in the artistic sector, objects, restoration and scenography where, in some cases, they prove to be truly irreplaceable.

Silicone rubbers is the excellent non-stick effect

One of the fundamental properties of silicone rubbers is the excellent non-stick effect towards the materials they come into contact with. This means that they do not adhere to the model.

Therefore, no release treatment is important, both on the model and in the mold. Furthermore, silicone rubbers have excellent reproduction fidelity down to the smallest detail, and good dimensional stability. Their elasticity and tear resistance allow you to easily demold.

Strong undercuts, pronounced reliefs and detailed carvings

With silicone rubber you can make casts of an infinite number of objects: statues, figures, bas-reliefs, architectural elements, rocks, fossils, tree trunks, etc.

You can also get casts on still wet clay. The rubber comes off easily and does not release greasy substances or residues that could damage the model.

Conclusion

The aluminum soft plastic lure molds can be common for reproductions with different materials, such as polyester resins, rigid or expanded polyurethane, plaster, marble, wax, cement, etc.

How to Make Soft Plastic Lure Molds? Best Guide 2022

How to make soft plastic lure molds? Before building any artificial in plastic resin, we will have to worry about building around it to be reproduced, a two-part mold.

There are two main construction methodologies

The original to be reproduced could be an already existing artificial on the market or a new subject built by us, perhaps using balsa wood.

How-to-Make-Soft-Plastic-Lure-Molds-2022

How to make soft plastic lure molds?

I use 3- or 4-mm plywood for the longer sides and 10 mm plywood for the two shorter sides. In this way we will be able to reuse them, without having to redo them every time.

We take our original, fix it or stick to it at both ends (head and tail), two steel wires. We can keep it raised halfway inside the plywood box.

Obviously, to do this, it will be necessary to make two cuts in the shorter sides of the box with the jigsaw up to approximately half height. How to make soft plastic lure molds? This operation will serve to create a small space (7/8 mm.) We will then pour the expensive silicone rubber. The remaining space of the box will be entirely occupied by the much cheaper plaster.

Method A: create a cylindrical or conical housing

Now we need to create a cylindrical or conical housing. This starts from the head of our lure and reaches the end of the mold. It will be good to use to pour the silicone rubber into the cavity left free by the plasticine.

Use a piece of nylon on the piece of marble

We then place the wooden box, with all its contents, on a work surface (I use a piece of marble) to prevent any spillage. How to make soft plastic lure molds? This keeps the empty part upwards. I recommend placing a piece of nylon on the piece of marble so that it can then be removed easily.

Quickly mix gypsum with water, in sufficient quantity to fill it, taking care to make a very liquid amalgam. It can easily fill every gap. The plaster sets in about fifteen minutes. We will have to act quickly, helping ourselves by cutting a small trowel to fill every smallest hole.

After about ten minutes, when the plaster has set, we will take a wooden (or marble) ruler. How to make soft plastic lure molds? With sharp edges about twenty centimeters long and, scraping slowly. We remove the excess plaster, above the box, leveling the surface until the sides of the wood emerge.

Now, we will allow the plaster to dry perfectly, for at least two or three days. It dries, small cracks form around the sides of the wooden walls and the plaster takes its natural white color.

 

Overturn plaster and begin to remove the plasticine

Now some space has formed again, the space necessary for the second plaster casting.

Before carrying out it, however, it will be necessary to sprinkle the surface of the dried plaster with a veil of detaching wax. We gently open the wooden box, and separate the two parts of plaster.

How to make soft plastic lure molds? Remove the plasticine

We have thus built two overlapping parts, two gypsum shells. This overlap will form the rigid reinforcement of our mold. Now we will sprinkle the artificial cleaned from the plasticine with a layer of release wax. We will prepare for the pouring of the silicone rubber for molds.

Join the two plaster parts with the help of ropes or rubber bands

We carefully close each slot with plasticine, with gummed paper or pieces of nylon. So as not to let the liquid rubber come out and we straighten the mold joined in plaster. How to make soft plastic lure molds? It holds the tube or the plastic cone, in order to facilitate the insertion of the liquid silicone rubber.

We catalyze rubber:

We will have to mix it for a long time with the tip of a large screwdriver, together with the necessary amount of catalyst.

The one I use requires 10% (ten percent) of catalyst and solidifies in 24 - 36 hours depending on the external temperature. For a mold of a medium / large size minnows, we will need 100 grams of silicone rubber and 10 grams of catalyst.
How-to-Make-Soft-Plastic-Lure-Molds

Pour the liquid through the plastic tube

How to make soft plastic lure molds? Now we can pour the liquid and catalyzed silicone rubber, through the plastic tube, until all the empty space around the lure and the tube itself are filled. But be careful to slowly pour the rubber, with the help of a small jug with spout, so as to let the silicone rubber flow slowly into the mold, in order to allow the air to flow towards the other, leaving the place to the rubber.

In this way the rubber will fill exactly the amount of space between the plaster and the original, allowing us to obtain a perfect mold.

How to make soft plastic lure molds? Rubber that manages to reproduce

Once the rubber has poured, the mold will be kept facing upwards, for the entire time necessary for its definitive solidification.

Now we can open our plaster mold, freeing it from the windings, we cut delicately with the blade of a sharp cutter, laterally the rubber, near the head, for about two / three centimeters on each side, in order to allow the original to extract.

Then we will continue the cutting operation, always following the contours of the plaster molds.

How to make soft plastic lure molds? Now we will detach the two parts of the mold; it is a very exciting moment, the moment of truth, because it is right now that we discover whether the steps of our upstream work have been correctly carried out.

Accommodate the plastic resin and the lure assembly

Having removed the original wood and cut the silicone rubber in two parts, one realizes with pleasure that the mold is finished, ready to accommodate the plastic resin and the lure assembly and to produce hundreds of baits ... super captivating.

At the end of the operation we will find two gypsum shells integrated with two parts of silicone; together they will form the mold to reproduce our lures.

Now the two-part mold is really finished

After drying, with a sharp cutter it will divide into two parts and the mold will be ready for use. How to make soft plastic lure molds? The same procedure will have to adopt if we have to reproduce Jigs or spinner bait heads and any other small parts.

In this case we will have to use inert sinking fillers (marble powder). It is to mix with the plastic resin. Moreover, it is to ensure that these details do not float, but rather cause the artificial for which they are intended to sink. We must be able to obtain at least 1 kg of silicone rubber for elastic molds and the relative catalyst.

How plastic injection molding works? Ultimate Guide 2022

How-plastic-injection-molding-works
General working principle of plastic injection machine

How plastic injection molding works? The basic plastic injection molding machine structure has shown the functions of each part working together. These parts operate on a common working principle.

Raw plastic (Plastic) is put into the material storage compartment through a hopper. The plastic granules in the cavity melt by a heater. We keep it in a liquid state until it enters the mold cavity.

The process of injecting plastic into the mold is similar to using a needle. The motor generates force on the helical screw. The screw operates in a clockwise direction creating a large pressure that pushes the plastic to the valve.

What is injection mold clamping system?

The mold clamping system has the role of fixing the mold under the impact of huge pressure. And the cooling system will quickly cool the product to push it out of the mold to continue a new press.

How plastic injection molding works? All presses have a central operating system that controls the entire operation of the machine.

Detail working principle of Horizontal plastic injection machine

Horizontal plastic injection molding machine is one of the most advanced presses available today. This machine originates from Japan.

The improvements of plastic injection machine bring positivity in production. Productivity and quality of pressed products are guaranteed, diverse and durable.

Plastic injection molding machine has various sizes for large molds and small molds. However, the size difference is relevant to the working principle of the horizontal plastic injection molding machine.

The working principle of the plastic injection molding machine

As learned about the plastic injection machine in detail in the structure and general operating principle of the above content, basically, the JSW machine is nothing else. It also works on the same principle: “Heating – injection molding – cooling – ejecting the product from the mold”.

 

How plastic injection molding works?  Injection molding machine is the most important machinery equipment common in plastic injection processing. In this article, we take a closer look at the structure of the injection molding machine and the parameters of plastic injection molding.

Details of injection molding machine structure

In general, an ordinary injection molding machine consists of 5 systems:

  • injection molding support system
  • Furthermore, injection system
  • Moreover,  clamping system
  • Mold system and control system.

Injection molding support system

How plastic injection molding works? The injection molding support system consists of 4 subsystems, each with its own function.

Body: is the part that has the function of linking the systems of the plastic injection machine together

Electrical system: includes electrical cabinets and wires, providing power, helping the motor to operate. The electrical system needs to be scientifically designed. Moreover, it helps to ensure the safety of the operator.

Hydraulic system: composes of pump, valve, and pipe system, motor... is the place to generate resources for closing and opening the mold.

The cooling system comes with the function of cooling the mold by water or Ethylene Glycol solution. In addition, it helps the plastic material to harden into the desired shape before ejection. Moreover, it solidifies the plastic into a shape before the product is ejected from the mold.

Spray system of injection molding machine

The injection system melts the plastic material under the influence of temperature, maintains the temperature of the liquefied plastic, compresses and degass it during the injection of the plastic into the mold cavity as well as the shaping of the product.

The injection system comes of a:

  • plastic feed hopper
  • Moreover, a plastic container
  • Similarly, heating rings
  • a screw
  • Furthermore, a nozzle and a self-opening return unit

How plastic injection molding works? During operation, when the screw moves backward, the wedge-shaped barrier moves towards the nozzle. The molten plastic will flow in front of the screw head. The screw moves forward, vice versa.

Clamping system

Clamping system with mold opening and closing function helps to hold the mold firmly while waiting for cooling and opens to push the product out of the mold.

The clamping system is composed of the pusher assembly, the clamp assembly, the connecting rods, the movable plate and the fixed plate.

Plastic Injection Mold system

The mold system is a plastic product forming injection molding system consisting of a fixed half and a movable half. In which, the fixed part carries the mold cavity (female mold) and the movable part carries the mold core (male mold).

How plastic injection molding works? The mold system with a very complex structure, basically includes the following components:

Guide and positioning system: including guide pin, guide bearing, positioner, positioning ring...

The system of leading plastic into the mold cavity: including the nozzle silver, plastic channel, nozzle...

Product pushing system: including push pin, return pin, support pin, support pin bearing, push plate, retaining plate, support block...

Cooling system: including water lines, grooves, heat pipes, connectors (hollow shaft pipes, faucets)...

Plastic Injection Molding Exhaust system:

The control system is the operating system of the injection molding machine. Injection molding parameters such as temperature, pressure, injection molding speed, position of hydraulic system parts clearly display on the control panel.

How plastic injection molding works? The control system is the basis for the injection molding machine to perform operations during the entire pressing cycle.

Parameters of injection molding

Different types of plastic injection molding machines will have different injection molding processing parameters. Some common features in the parameters that the plastic injection machine operator should understand include:

Spray speed

The injection speed has a direct impact on the shape, determining the characteristic properties of the product. It is necessary to set the standard injection molding speed based on the characteristics of the plastic injection machine and the plastic product you want to form.

If the pressing speed is too high, it will make the product not aesthetically pleasing, glossy, surface blurred or seam floating...

How-plastic-injection-molding-works-2022

If the injection molding speed is too low, it will cause the mold not to be filled, causing lack of material, shrinkage, deformation, and failure to meet the required size standards.

Injection pressure

How plastic injection molding works? Just like injection molding speed, injection pressure has an effect on the operation of the injection molding machine and on the characteristics of the formed product.

If the injection molding pressure k adjusts reasonably, it will affect the quality and aesthetics of the formed product. Usually, high injection pressure is common in the production of parts that require thin walls and high pressure is common in the case of thick product walls.

Press area of injection molding

Products with different technical requirements require different injection molding areas. The pressing area clearly defines and the setting is reasonable during the whole injection molding process.

Injection area is an injection molding machine parameter that can affect the clamping force, mold size and technical parameters of the plastic injection machine.
