A very common manufacturing process; molten plastics are injected at high pressure in to a mould to produce a solid part. The mould is made up of two parts called the ‘core’ and the ‘cavity’ that are the inverse shape of the product in question.

Mould quality is critical and they normally made from either pre-hardened/hardened steel, aluminium or beryllium-copper alloy. The choice of material depends on various different economic factors. For low volume and large products; pre-hardened steel is normally used for tooling due its relative cost over low wear resistance, its also relatively easy to maintain or modify. Hardened steel moulds are far the superior in terms of wear resistance but are a pain to repair or modify as any changes require the mould to be annealed, worked and then re-hardening.

Common as the process is, parts can easily turn out with problems. We have stable relationships with only the best suppliers using the most advanced equipment, they understand the importance of good preparation, well controlled materials and the set procedures that surround smooth production.
