The molds for compacting the alloy-diamond mixture can represent highly critical issues as a non-perfect pre-mould will result in a non-compliant tool after sintering. The Bws testing department, being able to test its products internally, in addition to guaranteeing high quality standards, is always active in the search for new materials and innovations, certifying the heat treatment obtained with vacuum technology. We produce kits for all presses on the market, or even to customer designs.
