The binderless sand casting vacuum process (also referred to as V-process) offers a tremendous amount of freedom to design engineers.

A carefully-designed and engineered casting can assist the manufacturing engineer with tremendous time, floor space, and cost savings.

The part in this example was originally a copper sand casting in the late 1960s. After that, the foundry created the part by machining and welding it out of solid billet.

Lost foam offers tremendous design flexibility by allowing multiple features to be oriented as required for the form, fit, and functionality compared to the conventional sand-casting process, which
