Trim Presses & Auto-Grinders

Castings need to be cleaned and finished after pouring. Specifically, the gates, runners, sprues, and flash must be removed.

A very efficient way to do this is to use a trim press. First, a trim press cuts the non-casting metal away from the casting. Next, the as-cast casting is placed in a specific fixture for that casting and inserted into the trim press envelope. The trim press then is engaged, and the press cuts the flash and gating system from the final part. This can be done in one motion or may take more than one depending on the casting.

Another way to remove the excess metal from an as-cast part is to place it into an automatic grinder. These grinders either move the tool to the casting or move the casting to the tool. In addition, they can utilize standard grinding wheels, diamond wheels, bits, burrs, or any or all of the tools mentioned above to clean the casting.

Automation is the future of the metal casting industry, and Carpenter Brothers, Inc. can take you there. So give us a call to discuss your project.
