Forming process where a piston presses the molten metal into a pressure-loaded casting chamber, which retains the pressure until the metal has solidified. Beskrivning The process Two molds [1] are clamped using hydraulic presses to withstand pressure from the molding process. The mold is typically water or oil cooled to increase their longevity. The metal to be used is melted in an external furnace. A predetermined amount of molten metal is added to the system through an opening into the antechamber [2]. Using a ram [3] the melt is pushed into the mold under high pressure which is then maintained while the melt solidifies. The mold is separated and the finished part is pushed out by means of an ejector [4]. In cases where burrs are formed post processing in the form of sanding is applied. Cold chamber die casting
