Our precision investment castings are manufactured via the lost-wax casting process, enabling one-piece forming of complex structures like special-shaped curved surfaces, deep holes and thin walls. We offer customizable material options including carbon steel, alloy steel and stainless steel, tailored to diverse strength and corrosion resistance needs. With dimensional tolerance within ±0.05mm and surface roughness Ra≤1.6μm, these castings feature dense microstructure, uniform mechanical properties and stable performance for heavy-duty, high-frequency working conditions. Ideal for transmission system components, hydraulic equipment parts and engineering machinery core structures, we support OEM/ODM solutions to meet your specific requirements.
