Wear, cracking or distortions of mould frames are the enemy of flawless plastic and light alloy products as well economically efficient manufacturing processes. SCHMOLZ + BICKENBACH Group provides customised tool steel that can overcome these problems. At Moulding Expo, SCHMOLZ + BICKENBACH’s steel production brands Sorel Forge and Deutsche Edelstahlwerke will showcase their special steel solutions for tool and die manufacture, including the new highly polishable pre-hardened steel grades SF-2000® LQ40 and SF-2050® as well as Thermodur E 40 K Superclean, a new high-performance hot-working tool steel resistant to hot cracking.
SF-2000® LQ40 and SF-2050®, the newest steel grades from Canadian steelmaker Sorel Forge feature excellent polishability and excellent machinability, especially for large-size applications requiring flawless surfaces, such as moulds for headlamp lenses or windshields of passenger cars. For particularly large plastic moulds, Sorel Forge offers the SF-2000 pre-hardened tool steel.

Thermodur E 40 K Superclean, a new hot-working tool steel developed by Deutsche Edelstahlwerke, withstands the highest working pressures and thermal loads used in the production of die-cast components, enabling longer tool life by a delayed formation of hot cracking. These features make Thermodur E 40 K Superclean particularly suitable for the dimensionally accurate reproduction of die-cast parts made of light alloys, including engine housings and suspension-strut domes.
