Sand Casting

Sand casting can be used to create parts from steel, stainless steel, gray iron, malleable iron, and ductile iron. Also known as sand molded casting, this process uses sand—usually mixed with clay or another bonding agent—as the mold material. Roughly 70 percent of all metal castings are created using this method.

Mold cavities for sand casting are created by compacting the sand mixture around an existing part, model, or pattern inside a multi-part molding box, called a casting flask.

If needed cavities can also be carved directly into the sand. After the top and bottom halves of the casting flask are assembled and the sand is dried, molten metal is then poured into the mold and left to cool. The casting flask is then removed and the sand is cleared away, leaving the completed part.

Sand Casting Advantages

Sand casting is a very popular method of casting for varied reasons, some of which include:

Low cost
Ability to cast very large parts
Both ferrous & non-ferrous metals can be cast
Low post-casting tooling cost

Sand casting can be used to produce a wide range of custom components, including large, heavy, and/or complex parts.

Small - medium - high order quantity

Product materials of cast iron, cast steel, super duplex, SST, copper based & aluminum based alloys.

CNC milling (Aluminum, brass, steel, zinc alloy, many others )
Sheet metal (Steel, Aluminum, many others)
Die Casting (ADC12,etc);
Finish :remove bur, sandblast, anodized, painting, printing, plating, high polish, mirror polish, blackening, powder coating, etc.
