Integrated Casting & Machining Capability
Our manufacturing system is built around the complete production chain of precision investment casting.
From wax pattern preparation and silica sol shell building to melting, pouring, heat treatment, machining and final inspection, each stage is managed according to defined process parameters and quality requirements.
Our low-temperature wax silica sol process is especially suitable for complex and high-precision steel components, providing excellent dimensional consistency and reducing unnecessary machining allowance.
