OHMA FlexFast™ Clinch Press

The OHMA FlexFast™ Clinch Press is the perfect union between several of CenterLine's flagship products, the OHMA™ Cylinder, the OHMA™ Press, and the FlexFast™ (flexible fastener) machine.

The OHMA FlexFast™ Clinch Press is designed to be used for operator-loaded parts that require clinch fastener installation. Utilizing the standard C-frame style design from the basic OHMA™ Clinch Press, we have incorporated the same modular design principles for tooling and safety as on a projection welding FlexFast machine allowing for a wide range of custom clinching applications.

The OHMA FlexFast™ Clinch Press can be used for both self-pierce and pre-pierced fastener installation. The standard OHMA FlexFast™ Clinch Press can be configured with a variety of fastener feeding options to help reduce cycle time based on the application and part geometry.
