The sand casting process involves creating a mold from a three-dimensional sand pattern, then filling the mold cavity with molten metal, which is then cooled and solidified. The benefits of sand casting are numerous. There are minimal restrictions on the shape, size, and material. The process is extremely efficient by using dry sand, green sand, or chemically bonded sand. Sand casting is a better option over die casting because it allows for low or high-volume production.

RMC's Sand Casting Capabilities

RMC 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

RMC's Inspection Capabilities for Sand Casting Parts

RMC's inspection capabilities are top of the line. Spectrographic and manual quantitative analysis; metallographic analysis; Brinell, Rockwell and Vickers hardness inspection; mechanical property analysis, low and normal temperature impact testing; cleanliness inspection; and UT, MT and RT inspection are all conducted on site at our facilities.

Our inspection equipment is top-grade. Our Speck spectrometer checks 28 chemical elements. Our Zeiss metallurgical microscope produces high-resolution images 1,000 times magnified, and our Zeiss cleanliness meter determines particle size and quantity to ensure materials meet or exceed the international standard. We use GE ultrasonic detectors to discover flaws, and have X-ray machines and accelerators that can scan castings with 200 mm maximum wall thickness.
