Metal Die Casting Services

Aluminum and zinc die casting with tooling, machining and finishing in-house — a stable route to complex housings at volume.

Casting and machining from one supplier

Die casting economics depend on the whole chain: tool design, casting parameters, machining datums and finishing all interact. Because our tooling shop, casting cell and CNC department sit in one building, we control that chain end to end — and when a casting needs a design tweak, it happens before the tool is cut, not after.

A typical program looks like this: DFM and mold-flow review, tool manufacture, first-article approval with CT/CMM reports, then cast, de-gate, machine, finish and ship — with the same part ever leaving our system.

  • Aluminum (ADC12 / A380) and zinc (Zamak 3 / 5) casting
  • Tool design, manufacture and maintenance in-house
  • Machining fixtures and CNC finishing planned with the tool
  • First-article inspection with dimensional and porosity reports
  • Powder coating, painting, anodizing and assembly to finish
