The complete choice of casting processes

Alumasc Precision has been developing zinc and aluminium cast components since 1945. Refinments in both the alloys and the process have expanded our applications to most market sectors. Size, shape, thickness, strength and precision combine to offer designers unsurpassed qualities in performance and visual aesthetics.

The basic die casting process consists of injecting molten metal under high pressure into a steel mold called a die. Die casting machines are typically rated in clamping tons equal to the amount of pressure they can exert on the die. Alumasc machine sizes range from 180/2000 tonne. Regardless of their size, the only fundamental difference in die casting machines is the method used to inject molten metal into die. The two methods are hot chamber or cold chamber. A complete die casting cycle can vary from less than one second for small components weighing less than one ounce, ranging from-two to-three minutes for a casting of several pounds, making die casting the fastest technique available for producing precise non-ferrous metal parts.
