12th Tooling Conference & Exhibition - Tooling 2022

Wear and in particular abrasive wear in injection molding is a core research topic for the institute of injection molding of polymers at Montanuniversität Leoben. The standard application-oriented test for abrasive wear of polymers on plastic mold steels is the platelet-wear-tester method in which two steel specimens form a thin wear slit. The glass fiber reinforced polymer melt is injected...

Corrosion-resistant mould steels are used to process chemically aggressive plastics such as PVC or PET in many plastic moulding processes such as extrusion, injection, blow and compression moulding. Free machining (sulfurized) grades are common choice for holders where the requirements are machinability and dimensional stability, whereas low sulfur grades are preferred for high surface finish...
