The use of plastic materials, especially in the automotive industry, is increasing day by day and the additives in them are changing rapidly. As conditions change, the properties expected from plastic injection mold steels increase. In cases where mold steels are insufficient, we offer solutions to increase mold performance with the MOLDPLUS PVD coating series.
Molds undergo deformation over time depending on plastic injection production conditions and especially the use of raw materials. In particular, damage mechanisms such as wear, sticking/sealing and corrosion occur. We have PVD coating solutions to postpone these damage mechanisms and extend mold life.
- Steel-Steel working surfaces (scrapers, cores, pins-pushers, wear/locking plates)
- Glass fiber (20%-50%) added raw material plastic injection molds (reinforced plastics)
- Solution to plastic raw material retention problems with coating
- Corrosive raw material plastic injection molds (surface darkening / oxidation)
- cuBe2 copper-beryllium alloy (Moldmax hh) coating composition to increase wear resistance
- Coating composition to increase wear resistance in patterned molds
