Die Casting Metal Casting Process

Die casting is a form of metal casting process whereby molten metal is under high pressure to a mold cavity machined into a precise shape. Most die castings such as zinc, aluminum, copper, magnesium, pewter, lead, and tin-based alloys, are limited to low melting points,. Once filled with the molten metal, a coolant is circulated to cool the part. After cooling, the die halves are separated, and the completed part is expelled.

At the beginning of the sequence, the lubricant is sprayed on the castings’ open cavities, the die guide bars, and the mechanical plunger. Because of the elevated temperature, some oil evaporates and creates a plume of fumes and mists. Some key points of consideration include protecting worker health, reduced tire out air make-up up to 80% in the course of recirculated conditioned air, extended machine life, diminished operational costs using reclamation of lubricants, enhanced product quality, decreased housekeeping costs, and fulfillment with the strictest state, local and federal environmental standards.
