Precision Steel Cast is a professional stainless steel investment casting manufacturer based in China. We help global OEMs, engineering teams, and sourcing managers turn complex metal geometries into high-tolerance, repeatable production components using the silica sol lost-wax (investment casting) process — supported by in-house CNC machining, heat treatment, and rigorous quality inspection.
Our Manufacturing Capability
We run a vertically integrated production line so you get one accountable supplier from prototype to volume:
- Tooling & wax pattern — injection tooling and wax assembly for repeatable patterns.
- Shell molding — silica sol zircon/alumina slurry shells for clean, dimensionally stable castings.
- Melting & pouring — controlled argon-protected melting of stainless and specialty alloys.
- Shell removal & cut-off — knockout, gate removal, and blast finishing.
- Heat treatment — solution annealing, hardening, and aging per specification.
- CNC machining — turning, milling, and drilling to print tolerances.
- Inspection — CMM, surface, and NDT (MPI/UT) as required.
Materials We Cast
We routinely cast austenitic, martensitic, precipitation-hardening, and duplex stainless grades, including:
- 304 / 304L and 316 / 316L austenitic stainless
- 17-4PH and 15-5PH precipitation-hardening
- 410 martensitic stainless
- 2205 duplex and other dual-phase grades
- Custom stainless and low-alloy specifications on request
Quality & Traceability
Our quality system is built around ISO 9001 principles with full material traceability:
- Material certificates (EN 10204 3.1) and heat numbers
- First-article inspection (FAI) and dimensional reports
- CMM verification of critical features
- Dimensional tolerances down to CT4–CT6 with thin-wall capability
Industries We Serve
- Pump & valve — corrosion-resistant bodies, impellers, and trim
- Marine — seawater-service castings and hardware
- Automotive — structural and functional components
- Medical — instrument and device housings
- Aerospace — precision brackets and fittings
- Food & chemical processing — hygienic, cleanable parts
