Why Aluminum Sand Castings?

Sand castings offer benefits such as cost effectiveness, quick turn around, and lower cost tooling that is often easily modified and adaptable.

How long does Green Sand tooling last?

The life of a green sand tool can last for years. Many tools can last over 50,000 shots depending on the complexity of the part and the tooling materials utilized.

What kind of surface finish do green sand castings offer?

Normal surface finish, depending on the pouring alloy, range from 200 to 560 RMS. Improved surface finish can be achieved with use of our in-house shot blast process as well as vibratory finish process.

What is the manufacturing capacity for green sand molding?

We have the ability to provide one piece per year up to thousands of castings per year. Our state of the art manual and automated processes give us the ability to produce castings from ounces up to 150 lbs.
