The cordless portable clinching gun for solar panel brackets delivers an output pressure of 30-60kn. This tool provides a highly efficient, one-step rivetless joining solution that requires no consumables. By eliminating the need for post-joining polishing or repainting, this method significantly reduces total manufacturing costs compared to traditional welding processes.

Our technologies are validated by major global clients. In automated production lines, we have partnered with Midea since 2022 to provide clinching solutions for control cabinets, improving assembly efficiency and reducing production costs. For high-strength automotive manufacturing, we successfully supplied self-piercing riveting and clinching systems to Mercedes-Benz in Fuzhou, passing extensive material tests and metallographic analysis.
