OEM custom gray iron casting products made by sand casting process from China casting manufacturer.
When we cast the gray cast iron, we strictly follow the chemical composition and mechanical properties according to the stardards or requirements from the customers. Besides, we have the ability and equipment to test if there is casting defects inside the gray iron sand castings.
The ferrous alloys which have carbon contents of more than 2% are called cast irons. Though cast irons can have a carbon percentage between 2 to 6.67, the practical limit is normally between 2 and 4%. These are important mainly because of their excellent casting qualities.
Gray iron is cheaper than ductile iron, but it has much lower tensile strength and ductility than ductile iron. Gray iron can not replace the carbon steel, while the ductile iron could replace the carbon steel in some situation due the high tensile strength, yield strength and elongation of ductile iron.
From the iron-carbon equilibrium diagram, it can be observed that cast irons have essentially cementite and ferrite. Because of the larger percentage of carbon, the amount of cementite is high resulting in very high hardness and brittleness qualities for cast iron.
RMC can pour gray iron castings using our green sand mold casting, pre-coated resin sand casting and no-bake mold casting processes 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 Casting Foundry 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 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 services are varied and extensive. We offer material advisory service and development, as well as advice from our technical experts on design and casting. We do 3-D CAD drawings, simulations, and component machining. We also offer cavity fill, solidification, tension and distortion services. We provide assembly, testing and qualification, heat treatment, and surface treatment. From start to finish, we have you covered every step of the way.
RMC is dedicated to the quality of our work, and our commitment to excellence ensures the highest customer satisfaction. As a global leader in high-precision, high-complexity, and mission-critical casting and machined components, we strive to meet and exceed the needs of our customers.
