With Maxit-Tool-Management, Sulzer Metaplas—a subsidiary of Sulzer Metco—offers a means of specially tailoring tools in accordance with process requirements. This concept enables the processes inside the tool and on its surface to be taken fully into account. The overall strength and ductility of the tool can be adjusted regardless of the surface hardness and the chemical processes on the surface. The subsequent Maxit combi-treatment adapts the surface of the tool to specific requirements. The combined application of surface heat treatment and coatings produces hard tool surfaces that are coupled with ductile cores. These coatings are mainly used for tools for the processing of various plastics and elastomers.
