        What is plastic worm mold: Step by Step Guide

        Feb 22, 2021

        Plastic molding, what is it and how does it works?

        Plastic is a material that is present daily in our lives. It is present in everything we touch and use. But we don't usually wonder how it works to take its shape. Moreover how does plastic worm mold work to take its final appearance?
        These first molds are usually come with steel or aluminum and various tests go through to verify the final result.?Once the necessary checks come, the actual plastic molding is easy to perform. Similarly, it generally takes place in heated barrels.

        plastic worm mold

        A list of the main types of molding includes:

        • injection molding
        • thermoforming molding
        • foaming molding
        • compression molding

        • sintering molding

        The main advantages consist in the high production rate, in the reusability of the molds even in subsequent times, in the low cost of processing, in the abundance of usable materials.

        The main disadvantages are the cost of the equipment, the cost of operation and the study time of the molds.

        More than 60 percent of serial and piece goods are made from various plastic worm mold.?The weight of the finished plastic part can be only a couple of milligrams, or it can reach several tons.?The range of parts is also quite extensive, from small parts used in microprocessors to large structures used as part of a structure.

        The casting of plastic products?is in great demand both among individuals and among various organizations.?Depending on the tasks and the purpose of the parts, casting can be performed in several ways.?Let's consider in more detail the most common of them.

        Thin-walled plastic worm mold casting

        Casting plastic products with thin walls requires careful attention to the design features of the cast part, as well as to the material of manufacture.?At the design stage, all calculations are performed on a computer in order to optimize the thickness of the part and its shape.

        Despite the fact that plastic worm mold technology requires special equipment and materials, with its help you can significantly save on consumables.?In addition, with thin-walled casting, the production cycle for one part does not exceed ten seconds, which makes it possible to manufacture large batches of products in a short time.

        Hot Channel Die Casting

        A more advanced plastic injection molding technology is the use of special hot runner molds.?These shapes are ideal for the manufacture of parts of high precision and quality.

        The special valve mechanism of the mold prevents the solidification of material residues on the surface of the product.?The injection of plastic is carried out in such a way as to prevent the sprue from separating from the finished product.

        In addition, with this method of casting, there is no production waste and all the plastic is used.?The most common products cast by this method are:

        • children's furniture;
        • furniture for public buildings:
        • furniture for retail outlets.

        Injection molding

        Plants for plastic injection molding are characterized by high productivity.?This equipment can use almost any type of plastic for the manufacture of parts.

        Adding to this work with complex shapes and the absence of the need for additional processing of products, we get the best option for mass production.?By the way, this casting method is quite applicable for small batches of parts, if custom-made plastics need to be cast quickly and with high quality.

        Plastic worm molding

        The last type of plastic product manufacturing that we will consider is blow molding.?This method is used mainly for the production of various plastic containers such as bottles or cans.

        With this method, depending on the equipment, it is possible to blow the billet in one or two directions.?Vessels that are inflated in two directions exhibit better mechanical and optical properties.

        Using plastic worm mold technology, you can get quality products with controlled wall thickness.?Neck dimensions are also under complete control and the finished product does not require further processing.

        Benefits of cooperation with professional company

        If you need to perform molding of plastic products, then ordering from professional company will give you a number of advantages:

        • execution of an order of any complexity and volume;
        • work is carried out in a short time and with maximum quality;
        • casting is performed on modern equipment.

        We will now see the methods to obtain plastic objects in various ways.

        The heating of the monomer is common to all processes so that, due to plasticity, the desired shape is obtained

        The application of melted polymer

        In this case, the polymer is introduced through a hopper that drops to the screw.?The spindle pushes the polymer that as it moves forward is heated by electrical resistances.

        Once at its destination, the melted polymer is placed in a mold that has a fixed and a movable plate.

        The polymer is introduced between both plates, it is left for a while to plastic worm moldcool down and when the movable plate is opened, the plastic piece comes out with the shape of the mold.

        Plastic extrusion molding

        ?

        In this method, the molten polymer pushes through the screw into the nozzle.?When leaving it takes the shape that the mouthpiece gives it.?At the outlet there is a cooling system.

        Compression molding

        The polymer comes in the form of granules, in a mold that contains a system to provide heat and keep it always warm.?The mold and counter mold join to heat the material and obtain the desired part

        Blow molding

        It is common in industry to make hollow parts such as bottles and certain containers.?

        Vacuum molding

        In plastic worm mold system, the starting point is a polymer sheet (red) that is placed on the mold, held by clamps.?As the air inside the mold extracts, the plastic descends. Moreover, it adopts the shape of the mold. Similarly, when the clamp opens up, we finally get the object.

        Plastic worm mold Adhesives.

        Generally, there is a wide variety of glues on the market with very specific applications.?Some adhesives, such as white wood glues, are specific for joining wood. And they are not useful for other types of materials. Similarly, others, such as epoxy resin, are more versatile and can join different materials.

        Basically, adhesives can be rigid or flexible.?Some join almost instantaneously while others need more time.?In addition, it is always important to see the instructions for use for a good bond

        As a general rule, the surfaces to be joined must be free of grease or dust.?Even skin oil can damage the bond.
