Die Casting Basics

Die Casting Basics

Die Casting Basics. Die is closed. Metal is drawn in to tool (plunger). Tool injects metal into cavity. Cavity continues to fill. (fractions of a second). Metal solidifies under pressure. Die is opened. Casting removed. Machine recovers to initial orientation (cycle starts over).
