    CNC EDM Die Making Precision Plastic Injection Molding 3D Modeling

    Precision Custom Plastic Injection Molds Moulds Design Tooling Die Making Service

    The plastic injection molding machine maximizes raw material use, unlike traditional manufacturing processes that cut away substantial amounts of the original plastic. There is minimal wastage in the plastic injection molding process.


    The process of injection molding undergoes six stages. The stages have to be completed in order and determine the quality of the final product.

    Stage 1: Mold closing

    The process begins by placing the final mold inside the plastic injection molding machine.

    The mold is divided into two halves that are attached to platens (steel clamps). A hydraulically powered clamping unit pushes the two halves of the mold together. It exerts enough force to ensure the mold is closed tight when the molten plastic is injected into it.

    Stage 2: Feeding

    Once the machine is started, the chosen plastic pellets or polymer granules are fed into the hopper which is a large container with an open bottom. The pellets or granules move from the hopper into a barrel, which contains a heating mechanism. Feeding the pellets or granules into the hopper can be done either automatically or manually.

    A reciprocating screw slowly moves the plastic pellets forward by way of sliding and rotating movements. The reciprocating screw is usually hydraulically operated. As the material enters the grooves of the screw, heating takes place through friction and by using high amounts (10,000 to 30,000) of pressure and heat.

    Once the granules have melted, the molten plastic is very quickly injected through a nozzle and fed into the mold cavity.

    Stage 3: Pressure holding

    The buildup of pressure packs and holds the molten plastic material within the mold. Holding pressure is consistently maintained to compensate for any material shrinkage.

    Stage 4: Cooling and solidifying

    At this point the plastic is allowed to cool and harden. The molten plastic within the mold begins to cool as soon as it makes contact with the mold’s interior surfaces. As it cools, the plastic solidifies in the shape of the mold.

    Stage 5: Mold opening

    During the cooling time, the mold remains closed and cannot be opened. The cooling time depends on the thermodynamic properties of the plastic material. Once it has hardened, the platens are opened up.

    Stage 6: Demolding

    The product is removed from the mold by an ejection mechanism that pushes the product out of the mold. Sometimes, a mold release agent is sprayed on the mold cavity’s inner surfaces before the injection of the plastic to help facilitate easy mold removal. Once the product has been removed, the mold can be clamped again for the next injection.

    The entire cycle can take anywhere between 2 seconds and 2 minutes. The process can be repeated as many times as required, ensuring consistently high quality molds.
