Sand Casting Capabilities
Sand casting is the oldest and most widely used casting process, accounting for approximately 70% of all metal castings worldwide. Molten metal is poured into a mold made of sand mixed with a bonding agent (clay, resin, or chemical binder). After the metal solidifies and cools, the sand mold is broken away to reveal the casting. Sand casting can produce parts from ounces to tons, in virtually any metal alloy, making it the most versatile casting process. It is ideal for low-to-medium volume production, large parts, and when a wide range of alloys is needed. Modern sand casting facilities use automated molding lines and 3D-printed sand molds for improved accuracy.

Sand Casting in San Jose — FAQ
How many Sand Casting providers are in San Jose, CA?
The San Jose-Sunnyvale-Santa Clara metropolitan area has approximately 2,800 manufacturing establishments, many of which offer sand casting services. The area employs about 65,000 manufacturing workers, ensuring a skilled workforce for your project.
How large of a part can be sand cast?
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.
What is the surface finish of sand castings?
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.
What is a sand casting pattern?
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.
How does 3D-printed sand molding work?
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.
