Casting characteristics

Proton-PM has some modern equipment that makes it possible to

  1. Produce sand cores made with the help of Laempe-supplied equipment using the Cold-Box-Amin process;
  2. Provide full product cycle for cast sections:
    • prepare auxiliary materials;
    • make wax samples using a range of compounds;
    • make ceramic moulds using ethyl silicate;
    • deal in mould-baking and air- and vacuum-based mould casting;
    • clean up the gating system;
    • deal in thermal treatment of castings in an automated furnace made by IPSEN (Germany);
    • deal in mould-etching.
  3. Carry out a range of casting quality control procedures:
    • visual control;
    • luminescent control;
    • X-ray control;
    • color flaw detection;
    • controlling the chemical composition of the product;
    • controlling the mechanical properties of the product.
