  2. Injection moulding - Wikipedia

    en.wikipedia.org/wiki/Injection_moulding

    Injection moulding (U.S. spelling: injection molding) is a manufacturing process for producing parts by injecting molten material into a mould, or mold. Injection moulding can be performed with a host of materials mainly including metals (for which the process is called die-casting ), glasses , elastomers , confections , and most commonly ...

  3. Injection mold construction - Wikipedia

    en.wikipedia.org/wiki/Injection_mold_construction

    Injection mold construction is the process of creating molds that are used to perform injection molding operations using an injection molding machine. These are generally used to produce plastic parts using a core and a cavity. Molds are designed as two-plate or three-plate molds, depending on the type of component to be manufactured.

    The design of injection moulded components can be further improved and optimised by using injection moulding simulation software such as Autodesk Moldflow [5] and SolidWorks Plastics. [6] This software works with components designed in CAD to simulate how a polymer behaves when it enters a injection mould cavity.

  5. Gas-assisted injection molding - Wikipedia

    en.wikipedia.org/wiki/Gas-assisted_injection_molding

    In gas-assisted molding, the plastic material is injected into the mold cavities like the regular injection molding process but only up to 70%~80% of the mold volume. The melted plastic in contact with the mold walls begins to solidify, then nitrogen gas is injected into the mold through strategically designed and placed gas inlets, providing ...

  6. Multi-material injection molding - Wikipedia

    en.wikipedia.org/wiki/Multi-material_injection...

    Multi-material injection molding (MMM) is the process of molding two or more different materials into one plastic part at one time. [1] As is the case in traditional injection molding, multi material injection molding uses materials that are at or near their melting point so that the semi-liquidous material can fill voids and cavities within a pre-machined mold, thus taking on the desired ...

  7. Injection molding machine - Wikipedia

    en.wikipedia.org/wiki/Injection_molding_machine

    The person designing the mold chooses whether the mold uses a cold runner system or a hot runner system to carry the plastic and fillers from the injection unit to the cavities. A cold runner is a simple channel carved into the mold. The plastic that fills the cold runner cools as the part cools and is then ejected with the part as a sprue.
