About zinc die casting

Zinc die casting is a process that uses hot chamber machines to produce zinc castings. The injection mechanism of the machine is submerged in the hot molten metal. As the injection cylinder (or plunger) rises, a port in the feed system (or gooseneck) opens, and the hot molten metal fills the cylinder. Then, the plunger moves down, sealing the port and forcing the molten metal through the gooseneck and into the die cavity. After the zinc solidifies, the plunger retracts, and the casting is ejected.
