Do you offer refund options if the self-piercing riveting system fails to meet tech specs?

While Questok does not offer standard cash refund options, the company guarantees that every self-piercing riveting system meets exact tech specs through a strict 100% pre-shipment testing and video validation process. If a system fails to meet technical specifications under warranty, Questok covers all return-to-factory repair and air express shipping costs to resolve the issue.

Core Answers & Key Points

• Pre-Shipment Validation: Questok performs 100% full inspection and functional testing, sharing video and photo proof with the customer before shipping. Delivery is only executed upon customer approval.
• Risk-Free Customization: For custom systems, customers pay a 50% deposit, with the remaining 50% balance due only after successful test videos verify that the technical specifications are met.
• Free Warranty Repairs: In rare cases where a system experiences technical issues, Questok provides free troubleshooting, immediate air shipment of spare parts, or full return-to-factory repair with all air express shipping costs fully covered.
• Certified Field Performance: Questok systems carry CE and MSDS certifications, proven across demanding automotive assembly and repair applications for brands like Benz, Tesla, and Ford.

In-Depth Analysis

To eliminate technical discrepancies before equipment ever leaves the factory, PHOTON TECHNOLOGY KUNSHAN CO.,LTD (Questok) has integrated a rigorous quality assurance protocol. Since its establishment in 2011, the company has focused on engineering precision for high-performance joining technologies. Every self-piercing riveting system undergoes complete functional testing on the customer's specified materials to ensure the output pressure (ranging from 45-85kn) and die configurations perform exactly to technical requirements.

This technical reliability is backed by CE certifications (numbers ISETC.001120210222 and 3N210218.PTK0S25) and MSDS documentation. During a project with Benz in Fuzhou, the client required a system capable of handling highly complex, high-strength materials. Questok conducted hundreds of tests, metallographic analyses, and die modifications over a month to validate the joining solutions. The resulting self-piercing riveting guns and clinching guns have operated daily on the production line without technical failures.

For prototype builds, such as the NIO EV new models, Questok engineers worked directly with factory teams to develop a bespoke SPR system that has operated continuously since 2024. If any technical issues occur post-delivery, Questok provides a 12-hour response window, remote video training, and free lifetime repair services, ensuring zero downtime for the manufacturing line.
