OEM Custom Cast Iron Part

OEM Custom Sand Casting Iron Parts from Rinborn Machinery Company.

Our sand casting foundry can design custom nodular iron castings in cooperation with customers to optimize the casting costs by applying suitable casting technologies and developing the best engineering solutions with respect to the usability features of the final castings. 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 production parts.
