DEW presents all-stainless steels for plastic moulds to meet demands of the plastic industry.
Demand for stainless steel plastic moulds is increasing more and more. Deutsche Edelstahlwerke (DEW) has put together a “package” of all stainless materials specifically for the requirements of industry. Whether plastic bottles, yoghurt cups, car seats, syringes and much more, almost every plastic product has its origin in a mould or a tool made of stainless steel. The trend in plastic mould-making is towards moulds made entirely of stainless steel.
However, mould-makers can often only machine stainless steels for their purposes with high machining costs. DEW has developed three stainless tool steels for different areas of application in order to meet both the increasing quality demands of industry and the requirements of machinability in the long term. This “All-Stainless Concept” consists of the materials Formadur 2083 Superclean, Formadur PH X Superclean and Corroplast. According to DEW, all three steels are corrosion-resistant, hard yet at the same time easy to machine. But each material also has its own strengths. Formadur 2083 Superclean impresses with its excellent wear resistance and polishability. In addition, the steel is very tough and easy to machine. Despite its very good corrosion properties, the Allrounder can be scar-etched. Formadur 2083 is suitable for injection moulding, compression moulding and extrusion in plastics processing. Formadur PH X combines strength and toughness and is also the first choice in terms of polishability. The steel also scores well in terms of weldability because it contains very little carbon. Due to its high resistance, Formadur PH X Superclean is particularly suitable for processing plastics such as PVC or aminoplasts, as the moulds often struggle with acid deposition.
