Vacuum die casting For porosity level of PK1
Disc breaking components which are safety critical required to withstand 140bar oil pressure. The porosity Standards for such applications are very stringent varying for 0.2 to 0.4mm this can be achieved only through vacuum die casting. This is a specialized process where the dies under locked condition are connected to the vacuum mechanism which continuously evacuates the air before and during the filling phase of casting hence achieving minimized porosity levels.
