Molding Process Selection

Green Sand Molding

Precision manual green sand molding uses manually formed green sand molds to make castings. This is an economical solution for many casting applications.

The benefits of precision green sand castings are many: low cost tooling, flexibility of modifying tooling or part geometry quickly, short lead times, easy production of prototype castings through high production quantities, thin and thick wall casting flexibility, exceptional “as cast” surface finish, intricate detail, complex coring and high integrity castings.

Pentz uses flasks (mold boxes) from very small (12”x16”) to very large (4’x20’ and 8x8’) to produce a wide range of precision green sand aluminum castings from 1 ounce to 4,000 lbs.
