What Is Sand Casting? - Monroe EngineeringMonroe …

Sand casting is a casting process that involves the use of sand-based mold. While other casting processes use molds made of plastic or metal, as well as other materials, sand casting revolves around the use of a sand mold. As a result, sand casting offers several unique advantages over traditional casting processes.

Foundry & Die Casting Robotics | Foundry Automation …

Higher output per hour and per shift, because the robot doesn't take breaks or get tired. Less scrap, because dies, cores and sand molds don't get damaged, and because the process is performed consistently, so metal is poured the same way and there's far less temperature variation. Higher material yields.

Foundry Says Robotic Sand Printing a "Game Changer" for ...
