BÖHLER Plastic Mould Steel

Plastic moulding requires unique properties from the tool material. At Uddeholm we have very good knowledge of the challenges from the plastic moulding Every tool has its own specific requirements – especially when it comes to the highly differentiated processing of plastics. Depending on requirements, various classic tool steels and remelted or powder metallurgically produced high-performance materials are used. BÖHLER offers the plastics industry a range of tool steels, proven and tested in practice and customised for the respective application. These guarantee high tool life, maximum precision during processing and perfect quality of the plastic surfaces.

BÖHLER plastic mould steels are used as tools and tool parts in numerous plastics processing methods, e.g. injection moulding and extrusion. Above all, customers see us as the market leader in the most versatile, stainless material programme for the plastics processing industry.

Special requirements for mould materials for plastics processing include:

  • Wear resistance, hardness when processing certain plastics (GRP) and at temperatures up to approx. 400°C
  • Corrosion resistance when processing certain plastics (e.g. PVC) and under critical cooling conditions
  • Mechanical strength and toughness (fracture resistance and resistance to plastic deformation)
  • Tools almost always need to be cooled
  • Partly very large dimensions
  • Polishability
