Injection Moulding Materials

Injection moulding is a formative manufacturing technology. Almost every plastic part created today is by Injection moulding, as it allows identical parts to be created in huge numbers, in a short space of time, and at very low cost per part.

Whilst the part cost is low, injection moulding has high set up costs, mostly from the cost to make the tools (using CNC) Mould tools range from a few hundred GBP to 6 figures depending on complexity.

The materials used for the tools varies depending on how many parts are to be made and the accuracy required. All thermoplastics can be moulded (a polymer which becomes soft when heated and hard when cooled). Some silicones, and thermoset resins are also possible to mould.
