The logical choice for high pressure die casting

Dyson Diecastings has been developing zinc and aluminum cast components since 1917. Refinements 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. Dyson Diecastings’ machine sizes range from 180/800 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 for producing precise non-ferrous metal parts.

High pressure die casting is relevant to components that feature/require:

  • thin wall
  • near net shape
  • lower weight
  • lower cost
  • high definition
  • surface finish.
