In industries where corrosion resistance, high strength, and complex geometry are non-negotiable, AISI 316 Stainless Steel Precision Castings produced via the advanced Mounted Lost Wax (V5) process set the benchmark for quality and performance. This sophisticated manufacturing technique delivers components with exceptional dimensional accuracy, superior surface finish, and outstanding metallurgical integrity, making it the preferred choice for critical applications across diverse sectors.
Premium Material: AISI 316 Stainless Steel
The foundation of this casting service is AISI 316 stainless steel, a molybdenum-bearing austenitic grade renowned for its enhanced corrosion resistance. The addition of molybdenum provides superior performance in chloride-containing environments and excellent resistance to pitting and crevice corrosion, outperforming standard 304 stainless steel. This alloy also offers high tensile and yield strength across a wide temperature range, good toughness down to cryogenic temperatures, and excellent fabrication characteristics. Its biocompatibility further expands its use into medical and food processing industries.
Advanced Lost Wax (V5) Precision Casting Process
The "Mounted Lost Wax V5" process represents the pinnacle of investment casting technology. It begins with the creation of a precise wax pattern, which is then "mounted" onto a central gating system (tree) for efficient production. The entire assembly is repeatedly dipped in ceramic slurries and stuccoed to build a robust, multi-layered mold. Once the ceramic is cured, the wax is melted out in a high-temperature dewaxing furnace (the V5 stage). The resulting cavity is then filled with molten AISI 316 stainless steel under controlled vacuum or atmospheric conditions. This process enables the production of complex, near-net-shape components with tight tolerances (typically CT4-CT6 per ISO 8062), thin walls, and surface finishes as fine as 3.2 μm Ra, significantly reducing or eliminating the need for secondary machining.
