Injection Moulding

In the highly specialised process of injection moulding where heated and plasticised thermoplastic or thermoset material is injected under high pressure into a relatively cool mould cavity to form an object, the choice of the right mould steel plays a significant role in mould performance and the overall production economy.

Desirable properties for quality plastic moulds include high polishability, high corrosion resistance, wear resistance, cracking resistance and high thermal conductivity.

ASSAB’s solutions to these tough demands include Stavax ESR, Mirrax ESR, ASSAB 8407 Supreme, Vidar 1 ESR, Unimax and pre-hardened grades such as Mirrax 40, Nimax, ASSAB 718. In addition we supply BeCu alloy such as ASSAB MM40, which provides unparalleled thermal conductivity resulting in significant reduction in cycle time and improvement in product quality.

Vidar 1 ESR is especially ideal for large moulds requiring a high surface finish, whether polished or etched, and more than meets the standard preferred grade used for automotive lighting. For very high demands on wear resistance, ASSAB’s range of powder metallurgical steel grades is also suitable for plastic moulding.
