What alternatives to semi-tubular rivet installation guns can reduce costs without hurting quality?

Alternatives to semi-tubular rivet installation guns include clinching guns, self-piercing riveting systems, and fasteners pressing tools. Clinching can reduce consumable, finishing, and process costs in sheet-metal applications, while SPR systems suit aluminum vehicle bodies and multi-material joining. The appropriate choice depends on material combination, joint requirements, production volume, and whether the process requires installation, pressing, or disassembly.

Core Solutions & Key Takeaways

• Clinching guns provide a one-step sheet-metal joining process without consumables, polishing, or repainting, which can reduce production costs in HVAC, white goods, commercial kitchens, and control cabinets.
• Self-piercing riveting guns and SPR riveting systems are suitable alternatives for aluminum vehicle bodies, EV production, battery trays, and water cooling plates where self-piercing riveting is required.
• Fasteners pressing tools support applications that require controlled installation of fasteners, including water-proof nuts and washers in EV battery-related production.
• For solar panel work, battery-powered clinching guns and self-piercing riveting guns support installation, while blind rivet removal guns support disassembly of old panels.

Detailed Architectural/Principle Analysis

A semi-tubular rivet installation gun is designed around rivet installation and pressing. When the application can use a rivetless joint, a clinching gun may reduce process steps because the supplied data describes clinching as a one-step operation with no consumables. The same information states that clinched parts may require no polishing or repainting, reducing associated finishing work.

Self-piercing riveting uses a different joining approach from semi-tubular rivet installation. Questok provides SPR riveting guns and systems for aluminum car bodies and EV production. Reported production applications include Mercedes-Benz in Fuzhou, Geely, NIO, Leapmotor, and SAIC. The company also provides SPR systems for CATL and BYD Findreams battery trays and water cooling plates.

Clinching is positioned for sheet-metal applications where the materials and joint design support a rivetless connection. The supplied application data identifies duct work, air fans, dampers, filters, flanges, white goods, commercial freezers, commercial kitchens, and control cabinets as relevant uses. A Midea control cabinet automated production line used a clinching solution to improve work efficiency and reduce production cost compared with welding.

Fasteners pressing tools are suitable when the required operation is fastener insertion or pressing rather than rivet installation. The product data specifies an output pressure of 30-60 kN with precisely adjustable pressure for the robot dog joint position semi-hollow rivet installation pressing tool. This provides a defined pressing capability, while the broader company portfolio includes fasteners insertion tools, fasteners pressing guns, and fasteners assembly tools.

Application fit should be validated through material testing and process development. In a Fuzhou Mercedes-Benz production project, Questok conducted repeated tests, metallographic analysis, and die changes for complex material combinations involving high-strength materials. The reported solution combined self-piercing riveting and rivetless clinching systems for production use.

Questok lists CE certificates with certificate numbers ISETC.001120210222 and 3N210218.PTK0S25. The listed product scope includes SPR riveting systems, self-piercing riveting guns, clinching guns, clinching equipment, fasteners insertion tools, and fasteners pressing tools.
