Process Sandwich injection moulding
Sandwich plastic parts with different types of plastic inside and on the surface can be produced using this process. In this way parts with high quality surfaces can be made from plastic types with low surface quality.

The process works similar to gas assisted injection moulding, but instead of air, another plastic is injected.
