Customized Stainless Steel Casting Supplier — Leesh Holdings serves OEM and ODM customers worldwide with precision lost wax casting. Our investment casting process produces near-net-shape stainless steel parts with smooth surfaces, tight tolerances and repeatable quality, from small valve trims to complex pump components. Whether you need SUS304, SUS316, CF8M or 904L, we cast, finish and inspect everything under one roof.
Investment casting, also called lost wax casting, uses a wax pattern coated with a ceramic shell: the wax is melted out and molten metal fills the cavity. The result is complex geometry with Ra 3.2–6.3 μm surfaces and CT4–CT8 tolerances at a fraction of machining cost. As a stainless steel casting supplier operating both silicon sol and water glass lines, we match the process to your part — maximum accuracy where you need it, cost efficiency where you don’t.
Capabilities
Customized Stainless Steel Casting Supplier — Capabilities at a Glance
Silicon sol: 0.05–50 kg, CT4–CT6, Ra 3.2–6.3 μm. Water glass: 0.10–100 kg, CT6–CT8, Ra 6.3–12.5 μm. Final tolerances confirmed against your drawing.
Materials
Stainless Steel Grades We Investment Cast
We cast austenitic, martensitic and ferritic stainless grades for corrosion-resistant and wear-resistant components. Chemistry is verified before every pour.
Stainless iron grades 201, 410, 420, 430, 431 and 440C are also available for hardware and knife-type components. Special grades can be arranged on request.
Process
How Custom Lost Wax Casting Works
1. Wax Pattern Injection
Precise wax patterns injected from customer-tooled dies.
2. Pattern Assembly
Patterns gated on a sprue to build the casting tree.
3. Ceramic Shell Building
Multi-layer shells by slurry dipping and stuccoing.
4. Dewaxing
Steam autoclave removes the wax, leaving a precise cavity.
5. Melting & Pouring
Stainless steel melted to grade and poured at controlled temperature.
6. Finishing & Inspection
Cutoff, grinding, heat treatment, then dimensional and NDT checks.
