The components featured here represent our expertise in Investment Casting (Lost Wax Casting) combined with secondary CNC Machining. From complex mechanical links and gear shafts to precision fluid control fittings and brackets, our products are engineered for durability, corrosion resistance, and geometric complexity. We do not just sell off-the-shelf parts; we transform your engineering drawings into finished, inspection-ready components.
Ideal Applications: Industrial Machinery Automation Systems Fluid / Valve Systems Heavy Equipment
Process & Manufacturing Insights
At Sunmy, we utilize a hybrid manufacturing approach to ensure both cost-efficiency and high precision:
Investment Casting
Primary lost-wax forming allows us to create complex, near-net-shape geometries (as seen in chain links and housings) with excellent surface finish and material integrity, significantly reducing machining costs.
Precision CNC Machining
Post-casting, we utilize advanced CNC turning and milling centers to machine critical dimensions—including bores, internal/external threads, and precision mating surfaces—to tight tolerances.
Surface Finishing
We offer tailored treatments ranging from standard bead blasting (matte finish) to high-spec mirror polishing and electropolishing, ensuring parts satisfy both aesthetic and environmental resistance standards.
