Plastic Moulding Steel
Choosing the optimum mould material for best tooling and production economy.
When a new moulded part is to be produced many important decisions have to be made in order to fulfill all requirements set. Decisions will depend on plastic material, production method, multi or single cavity, number of parts to be produced, tolerance and surface finish.
Right choice of tool materials for plastic moulding tools, should achieve:
- High surface finish
- Corrosion resistance
- Wear resistance
- High thermal conductivity
- Good surface finish after EDM or photoetchin
