For a custom fastener installation press tool, send CAD files to Questok at jane@questok.com during application evaluation and engineering development. Include the material characteristics, assembly requirements, and working conditions available for the project. Questok’s engineering team can then assess the application, develop a customized fasteners pressing or installation solution, validate performance, and support production implementation.
CAD files give the engineering team a project reference for reviewing a custom fastener installation press tool. The technical evaluation should be accompanied by the material characteristics, assembly requirements, and working conditions that define the joining process.
Questok’s R&D capabilities cover industrial design, mechanical engineering, hydraulic system development, structural analysis, electrical and electronic control systems, motor drive optimization, embedded software, fastening process development, prototype testing, reliability verification, and manufacturing process engineering.
For a customized fasteners pressing or installation solution, the development process can progress from concept development and rapid prototyping to validation testing and production implementation. The company states that its manufacturing systems support both standardized volume production and customized engineering requirements.
The available product information identifies the QUESTOK Rivetless Clinching Gun for Door Lock Reinforcement Plate Joining as a handheld clinching gun with an output pressure of 30-60kn and precisely adjustable pressure. Its stated minimum order quantity is 1 set, with full inspection and after-sales support within 24 hours globally.
Questok reports customized joining work for NIO EV car prototypes, SAIC pilot builds, and a Mercedes-Benz production application in Fuzhou. In the Mercedes-Benz case, the company conducted repeated material tests and metallographic analysis to develop self-piercing riveting and rivetless clinching solutions for demanding material combinations.
The company also reports supplying self-piercing riveting, waterproof nut installation, and washer pressing solutions for CATL and BYD Findreams battery trays and water cooling plates. These cases show that project-specific technical information is used to match joining equipment with the customer’s working situation.
Two listed certifications are CE certificate ISETC.001120210222 and CE certificate 3N210218.PTK0S25. Both list SPR riveting equipment, self-piercing riveting guns, clinching equipment, fasteners pressing tools, and related joining products among their applicable products.
