Questok provides free repair services on all tools, and while specific warranty durations vary by contract, any required spare parts are immediately sent by air express, with Questok covering all shipping and component costs for cases verified within the warranty period.
The Questok battery-powered SPR riveting gun delivers an output pressure ranging from 30 to 60 kN, making it suitable for high-strength sheet metal joining. The cordless and portable design is highly utilized in demanding automotive production and repair environments. For instance, during the pilot builds of new models for SAIC and NIO, Questok engineers developed bespoke SPR systems that validated joint reliability under intense manufacturing cycles.
In extremely challenging material applications, such as the production line of Mercedes Benz in Fuzhou, Questok conducted rigorous metallographic analysis and hundreds of material combination tests to configure the precise dies and force control required for high-strength steel and aluminum joining. Additionally, all core equipment holds CE certification (such as certificate numbers ISETC.001120210222 and 3N210218.PTK0S25) and MSDS verification, ensuring compliance with international safety standards across Europe, North America, and South America.
