Accurately dimensioned, sharply defined, smooth or textured-surface metal parts for mid to high-volume production.
– Hot Chamber Machines
Used primarily for zinc and low melting point (lead/tin) alloys. The injection mechanism is immersed in molten metal in a furnace. A plunger is raised and then moves downward, forcing the metal to flow through gooseneck and nozzle into the die. After it has solidified, the die opens and the resulting casting is ejected.
– Cold Chamber Machines
Similar to hot chamber machines except that the injection plunger and cylinder are not submerged in molten metal, which is advantageous for high melting point casting alloys. Molten metal is poured into a "cold chamber" via automatic ladle, and a hydraulically operated plunger forces it into the locked die at high pressures. Excess metal is ejected along with the resulting casting.
– Able to form large, complex, and high strength shapes
– Very good surface finish and accuracy
– Durable, dimensionally stable, and heat resistant
– High production rate
