Investment Casting: High-Precision Metal Parts Manufacturing Service

Investment Casting: Precision and Complexity Combined

Investment casting, also known as lost wax casting, is a premium manufacturing process that creates high-precision, complex metal components with exceptional surface finish. Leesh Holdings specializes in investment casting services, catering to global clients in aerospace, automotive, medical, and industrial machinery sectors.

Our investment casting process ensures tight tolerances (CT4-CT7) and intricate details that traditional casting methods can’t match. We work with a wide range of materials including stainless steel, carbon steel, alloy steel, and non-ferrous metals, adhering to international standards such as GB, ASTM, DIN, and JIS.

From tooling design and wax pattern creation to shell building, casting, and finishing, we provide end-to-end solutions. Each component undergoes rigorous quality inspection using advanced equipment like CMM, spectrometers, and non-destructive testing (RT, UT, MT, PT) to ensure consistent quality and performance.
