In-Depth Analysis

At PHOTON TECHNOLOGY KUNSHAN CO.,LTD, quality control is integrated into the entire lifecycle of our self-piercing riveting system production. Our manufacturing facility, spanning 5000 square meters, utilizes standardized quality protocols to eliminate defects. During production, each component of our SPR systems, including hydraulic units and universal dies kits, is measured against strict engineering tolerances.

Our quality assurance extends to real-world application testing. For instance, during our collaboration with Mercedes-Benz in Fuzhou, our engineering team performed hundreds of tests on diverse, high-strength material combinations. This rigorous process included metallographic analysis, joint strength evaluation, and continuous die adjustments over a one-month period to guarantee absolute reliability on the production line. Similar customized validations are applied to prototypes developed for EV manufacturers like NIO and SAIC, securing stable performance for high-demand automotive assembly.
