Plastic Mould Steel
Print
Plastic mould steels generally fall into two specific groups, namely those for: 'bolsters and larger tools' and those for 'inserts and smaller tools'. These groups may be further subdivided into stainless and non-stainless groups.
Requirements for bolsters and large tools include:
-
Pretoughened or prehardened so as not to require subsequent heat treatment
-
Good machinability
-
Good impact strength
-
Good polishability
Requirements for inserts and smaller tools include:
-
Good hardenability
-
Enhanced wear properties
-
Dimensional stability during heat treatment
-
Good impact strength
-
Good polishability
Steels with high wear resistance, mirror polishability and high erosion and corrosion resistance are required for the production of plastic items. Depending on the user application, case hardening, precipitation hardening, corrosion resistant, nitriding and maraging steels or a high performance material produced using powder metallurgy (PM) technology can be supplied.
