PLASTIC INJECTION MOLD TOOLING

Plastic injection molding can be defined as a process where molten plastic is injected into a an aluminium, ceramic or steel mold, where the mold cavity is shaped like the end product, and forced under a very high pressure into the mold cavity where it cools and hardens to the shape formed by the cavity. It is the design of the core and cavity of the plastic injection mould tooling is that gives the final product its shape, but there are other functions of the mold tooling that are important for the precise formation of the final product. Molds can be single cavity or have multiple cavities. In a multiple cavity mold each cavity can be identical and produce the same parts, or they can be unique and form multiple different parts; offering cost savings in production.

Our Amco plastic injection tool molds are generally made from tool grade steels and these are best suited for serial tooling and large production runs. Stainless steel and aluminium injection molds are not suitable for volume production or for forming parts with narrow dimensional tolerances, because the material has mechanical properties that don’t lend themselves to large volume and that are prone to wear, damage and deformation during the part manufacturing process.
