Frequently Asked Questions

What types of pump and valve components do you die cast?

Valve bodies, bonnets and end caps; pump housings and volutes; impeller and rotor components; manifolds, fittings and threaded ports; plus motor-pump assemblies that combine the pump chamber and mounting features in one casting.

Sand casting suits one-offs and very large parts. Die casting wins on surface finish, dimensional consistency and unit cost once volumes justify tooling. If your volume sits in the grey zone, we assess both routes at the DFM stage and tell you honestly which fits.

Most housings and bodies are cast in aluminum alloys such as ADC12 and A380 for strength, pressure-containing sections and corrosion resistance. Small precision components are cast in zinc alloys (Zamak 3/5) where fine detail and plating quality matter. Final alloy is confirmed at DFM.

Yes. We work from 3D models, 2D drawings with critical tolerances, or physical samples. The DFM review covers wall sections, draft, port positions and sealing-face machining allowances before tooling is cut.

As-cast and machined surfaces are toleranced separately in the DFM review. Sealing faces, bearing seats and threaded ports are finished by CNC to ±0.02 mm on critical features, verified by CMM (sampling per QC plan); routine dimensions are checked with calipers and gauges.

Powder coating and e-coating for corrosion protection, and plating for zinc fittings. Coated parts are verified with cross-hatch adhesion testing, thickness measurement and color checks.

Tooling development takes 35–45 days, with first samples 10–15 days after tooling completion and production in 30–45 days. We review and quote low-volume projects case by case, including volumes many factories decline.
