WebbInjection molding is a forming process where molten material is injected into a mold and then cooled to form the desired end product. Injection molding is possible with several polymers (thermoplastics), including polymers produced with glass or metal additives. WebbIt is a casting process and there is normally no pressure involved which means that the material cannot be controlled in the same way as high pressure processes such as injection moulding. There are many variables that can affect production and the end product such as ambient temperature and humidity, type of mould, material …
