Manufactur standard Gray Iron Green Sand Casting - Steel Sand Casting Foundry – RMC Foundry Detail:

Steel Sand Casting Foundry from China with Custom and CNC Machining Services.

Sand casting is one of the most popular and simplest types of casting, and has been used for centuries. Sand casting allows for smaller batches than permanent mold casting and at a very reasonable cost. Not only does this method allow manufacturers to create products at a low cost, but there are other benefits to sand casting, such as very small-size operations. Sand casting also allows most metals to be cast depending on the type of sand used for the molds.

Ideally suited for complex geometries, sand casting takes advantage of sand’s inherent compactability, refractory nature and recyclability to produce relatively inexpensive molds. Sand casting requires a relatively low investment and allows for quick tooling development and part changes at a reasonable cost. As a result, it’s well suited for working through the evolution of designs and for lower volume casting parts.

In RMC casting foundry, we uses sand casting for parts made of grey iron, ductile iron, carbon steel, steel alloys or aluminium. Part weights can vary from tens of grams to hundreds of kilograms. The applications of sand casting parts range from small parts like gears, pulleys, connecting rods, brackets and propellers to large components such as pump components, pipeline parts, manifolds, engine blocks, cylinder heads and transmission cases.

We ensure our customers have the highest quality parts on time and on budget by providing full turn-key services, including assistance with design and material selection through heat treatment, machining, surface finishing, assembly and painting. Apart from the green sand casting processes, we are also using other casting processes, such as pre-coated resin sand casting (hot shell and core molding), furan resin sand casting, investment casting, lost foam casting and vacuum casting.
