Geo-Clinch® Sheet Metal Clinching Solutions

Provides a non-rotating connection of sheet metal parts thereby setting the geometry between two parts.

Achieve proper GD&T orientation in a single press stroke.

BTM now designs, engineers, assembles, and manufactures the Geo-Clinch® line of clinch joints which provide a nonrotating connection of sheet metal parts thereby setting the geometry between two parts. Using only a single stroke, Geo-Clinch® joints will "geo-set" 2 sheet metal parts in their proper GD&T orientation. Parts can then be transferred to secondary fastening operations without complex and expensive tooling for locating and clamping. Joints designed, engineered, assembled, and manufactured under the Geo-Clinch® line consist primarily of Oval-Loc® and Lance-N-Loc® punch and die tooling.

With Oval-Loc® or Lance-N-Loc®, only a single joint is needed to obtain rotation-resistance.

ClinchClamp

ClinchClamp

Pneumatic Linear 6 Ton The ClinchClamp uses an economical swing action to open the unit for easy loading and unloading of the work piece.
Closing the unit includes the swing action being locked and combined with a short, straight line force stroke which facilitates better tooling performance.
Part locating and clamping can also be designed into the unit to satisfy the GD&T requirements of the work piece assembly.
