OEM Brass Sand Casting Valve Parts from China Manufacturer

As an OEM brass sand casting parts manufacturer and foundry, we can pour iron castings using our No-bake process up to ten tons finished weight in gray iron castings and ductile iron castings, and up to five tons in steel castings and stainless steel castings. RMC can produce casting parts in a wide variety of materials, including grey iron, ductile iron, stainless steel, carbon steel, wear-resistant steel, and heat-resistant steel based on different standards from China and overseas.

RMC's experience in creating high-end sand castings from high-grade materials and consisting of complex geometries is beyond comparison. In our high-tech facilities, we offer both machine and manual molding operations in our resin sand casting processes. We produce parts in low-to-high volumes and pour castings ranging from 0.5 kgs to 5 tons. Our green sand castings range from 0.5 kgs to 1000 kgs
