Plastic Mould Steels
Increasing use of plastic products expands
the use of steels for plastic mould applications. Manufacturers of plastic
products need dies with a long operation period that will retain their
high standard quality on a continuous basis. When selecting steel for
plastic moulds, the following major factors are of vital importance :
type of plastics, plastic moulding method, size and shape of product and/or
die, size of series, demanded product surface quality, operation mode,
preparation of dies. Steels for plastic moulds need to have the following
characteristics : high wear and corrosion resistance, hardness, toughness,
good polishability, surface texture properties, machinability, minimal
dimensional changes in heat treatment.
The properties of this category steel are:
