SERVICES
Our precision iron casting process begins with selecting high-grade materials. We utilize grey iron casting for its excellent vibration damping... or ductile iron castings for high strength... As a specialized foundry for VMC parts, we then employ the furan resin sand casting for large parts process. This method creates strong, stable molds that ensure high dimensional accuracy and a fine surface finish.
After casting, components undergo an important aging process. This involves a combination of natural outdoor aging and controlled thermal treatment (annealing). This dual approach effectively relieves internal stresses from the casting and cooling phases, preventing future distortion and ensuring the long-term dimensional stability required for sustained machine accuracy.
Once the casting is stabilized, our in-house CNC workshop begins the machining process. We perform multi-stage machining, starting with roughing to remove bulk material, followed by fine machining to achieve final specifications. Our equipment, including large gantry machining centers, enables us to meet tight tolerances on all critical surfaces.
Before shipment, each component will undergo a comprehensive final inspection. We use coordinate measuring machines (CMMs) to verify the dimensional accuracy, which is of vital importance for the gray cast iron machine parts that are subjected to high stress.
