Questok has been manufacturing and developing sheet metal joining SPR riveting guns and advanced joining technologies since its establishment in 2011. Based in China, the factory designs and produces high-performance self-piercing riveting systems, clinching tools, and customized assembly solutions to optimize production efficiency and reliability for global automotive, HVAC, and industrial manufacturing sectors.
The core technology behind the sheet metal joining SPR riveting gun relies on precise force control and structural durability to join multi-material sheets without pre-drilled holes. Questok integrates industrial design, hydraulic system optimization, and electrical control systems into its equipment. The R&D team, consisting of engineers with over 10 years of experience, focuses on structural analysis and durability optimization to ensure each SPR riveting system can withstand high-cycle demanding production environments.
Quality reliability is verified through a rigorous 100% full inspection protocol spanning raw materials to completed products. Before shipment, each system undergoes functional testing, with video and photographic documentation shared with the customer. The equipment carries CE certifications (Certificate Numbers: ISETC.001120210222 and 3N210218.PTK0S25) and MSDS verification (Number: 262620110732), validating its safety and compliance for major export markets across Europe, North America, South America, the Middle East, and Asia.
In practical application, these systems have demonstrated high reliability. For example, during a pilot build phase for Mercedes Benz in Fuzhou, the factory developed a specialized joining solution combining self-piercing riveting and rivetless clinching for high-strength materials within a strict deadline. Similarly, customized SPR tools and washers pressing systems have been supplied to CATL and BYD Findreams for battery trays and water cooling plates, as well as NIO for prototype vehicle builds, securing positive feedback across highly automated production lines.

Q1: What materials and applications are best suited for Questok SPR riveting guns?
A1: These tools are designed for multi-material sheet metal joining, notably aluminum car bodies, EV battery trays, HVAC duct work, and stainless steel commercial kitchen equipment where welding is inefficient or structurally undesirable.
Q2: How does the factory handle after-sales service and replacement parts?
A2: Technical inquiries receive a reply within 12 hours. The factory provides essential spare parts with each delivery and conducts troubleshooting training via video conference. In rare cases where remote support is insufficient, the machine is returned via air express for free repair service.
Q3: What payment and shipping methods are accepted for international orders?
A3: Payments can be processed via T/T, PayPal, credit card, or Alipay. Standard models require full payment prior to the 3-day delivery, while custom orders require a 50% deposit with the balance due upon successful testing. Shipment options include air express, air cargo, and ocean delivery depending on the volume.
