Stainless steel mixer tap casting

Products & applications

We are a build-to-drawing factory. The six families below are where our tooling and process experience runs deepest, and all of them sit inside our ISO 9001:2015 certified scope.

Stainless steel faucet castings
01 — Sanitary

Faucet & sanitary ware

Bodies, spouts, handles and mixer components in stainless steel, finished to a visible-surface standard. These parts have to seal, thread cleanly and survive polishing without pinholes showing up in the chrome line.

  • Single-lever and two-handle faucet bodies
  • Spouts, aerator housings and handle levers
  • Shower and bath fittings
  • Leak tested before packing
02 — Fluid transfer

Pipe fittings & connectors

Threaded and welded fittings cast close to net shape and machined to thread gauge. Investment casting keeps the internal bore smooth and the wall thickness even, which matters for both flow and pressure rating.

  • Elbows, tees, crosses and reducers
  • Unions, couplings and threaded adaptors
  • Sanitary and industrial grades
  • Thread inspection with go / no-go gauges

Cast stainless steel valve body
03 — Pressure parts

Valve & pump components

Pressure-carrying bodies, bonnets, covers and impeller parts. Chemistry is confirmed by spectrometer on every heat and finished parts are leak tested, because a porosity problem found by your customer is the expensive kind.

  • Ball, gate and check valve bodies
  • Pump casings, covers and impellers
  • Machined sealing faces and threaded ports
  • Material certificate for the heat, shipped with the goods
04 — Hardware

Hardware, marine & horse tack

Small stainless steel hardware where finish and strength both matter. High-mix, repeat-order work that suits our automated wax and shell lines.

  • Buckles, rings, snaps and clips
  • Stainless steel horse tack hardware
  • Marine and architectural fittings
  • Polished, satin or blasted finishes

05 — Kitchen

Kitchen utensils & foodservice

Stainless steel kitchen utensils and foodservice components. These parts are handled by people every day, so the finish and the edges matter as much as the dimensions — and the alloy has to stay food-safe through polishing and cleaning.

  • Utensils and handles
  • Foodservice equipment components
  • Polished and deburred visible surfaces
  • Covered by our ISO 9001:2015 certified scope

Product photography for these two families is being prepared. Ask us for sample photos of a specific part in the meantime.

06 — Machinery

Motor frames & machinery parts

Motor frames and metal machinery spare parts. Structural castings like these are judged on dimensional stability and on the machined mounting faces, because everything bolted to them inherits whatever error the frame carries.

  • Motor and pump frames
  • Machined mounting and locating faces
  • Metal machinery spare parts
  • Covered by our ISO 9001:2015 certified scope

Custom OEM

Not on this list? That is normal.

Most of what we pour is a customer's own part. If your component is a stainless, carbon or alloy steel casting that needs machining afterwards, send the drawing and we will tell you honestly whether investment casting suits it.

What to send2D drawing (PDF / DWG) or 3D model (STEP / IGES), material grade, annual and batch quantity, surface and test requirements
What you get backManufacturability comments, proposed process route, tooling cost and unit price
SamplingTooling, first article with dimensional report, then production release after your approval
