Expert Sand Casting in Newark, New Jersey

The New York-Newark-Jersey City metropolitan area has approximately 900 manufacturing establishments, many of which offer sand casting services. The area employs about 18,000 manufacturing workers, ensuring a skilled workforce for your project.

Sand casting can produce parts from a few ounces to over 100 tons. Very large castings include engine blocks, machine tool bases, ship propellers, and industrial pump housings. There is essentially no upper size limit for sand casting.

Standard sand casting surface finish is 250-500 Ra microinches (6-12 Ra μm). Shell molding and precision sand processes can achieve 125-250 Ra (3-6 Ra μm). Critical surfaces are typically machined after casting to achieve required finish and tolerances.

A pattern is a replica of the desired part (with allowances for shrinkage and machining) used to create the sand mold cavity. Patterns can be made from wood, plastic, or metal. Wood patterns are inexpensive for low volumes; metal patterns are durable for production.

3D-printed sand molds use binder jetting technology to build sand molds and cores directly from CAD data without patterns. This eliminates pattern costs, reduces lead time to days, and enables complex geometries impossible with traditional patterns.
