Green Sand Molding Machines

Machine Precision Green Sand Molding

The term “green sand” refers to the fact that temper water is used to activate the clay in the sand to bind the sand in the mold just long enough to build a mold and pour aluminum. This process builds a casting with a superior finish. Pentz Cast Solutions’ team of highly skilled engineers can manually green sand molds to produce the absolute best “as cast” finishes in the industry. Our skilled technicians leverage their unmatched experience with our programmable controls to create extraordinary smooth, detailed castings with a .150 RMS finish. Manual green sand molding allows us to create simple moldings at lower costs than automatic green sand molding processes. We also offer a full selection of casting treating and aftermarket services from light assembly to Kanban to NDT Real Time X-Ray to save you time during your molding production process.

Manual vs. Automated Green Sand Molding

It is important to consider the benefits of manual and automated green sand molding processes to ensure your castings are of the highest quality and meet your application requirements. Manual green sand casting has lower set-up costs than traditional casting methods. Manual castings also provides more versatility, as castings can be made from plastic, wood and even reclaimed material. Manual green sand castings allow you to produce very small or very large casting parts.
