Plastic products must meet highest requirements regarding accuracy of size and fit in every industry – from moulds for flat-screens to bumpers for the automotive industry.
In order to increase the material-related potential, Deutsche Edelstahlwerke have developed Formadur 400, which exceeds the previously attainable surface qualities and polishing results. This steel is specially developed as an enhancement of the prehardened standard grades 1.2311 and 1.2738.
Formadur 400 is the ideal choice for precise and efficient manufacturing of complex and large-shaped moulds for plastic forming. Furthermore, this steel offers good machinability, weldability and an outstanding quenchability to its core. Thanks to this, Formadur 400 has a very homogeneous hardness profile of approx. 400 HB across the whole cross section. Consequently, the steel has excellent burnishing qualities and best texturing properties.
For high demands on burnishing qualities, Deutsche Edelstahlwerke offer Formadur 400 in electro-slag-remelted condition – Formadur 400 Superclean. The remelting process leads to best polishing results due to a more homogeneous microstructure, the company says. For applications requiring a lower hardness level of up to 355 HB, Deutsche Edelstahlwerke are also launching the prehardened plastic mould steel Formadur 320 at Moulding Expo. | rs
