Pressure die castings contg. no porosity - made in multi:cavity die with large ingates and interconnected air escape holes

摘要

During the casting operation, the filling chamber of the pressure die casting machine is kept at 200-250 deg.C.; and the speed of travel of the molten metal into the die is maintained at 0.05-0.1 metre/second. The pref. die contains an ingate with a cross-section.
