What pressure rating is recommended for an auto collision repair SPR riveting system to handle high-strength steel?

For an auto collision repair SPR riveting system handling high-strength steel and aluminum car bodies, a recommended output pressure rating of 40 to 80 kN (kilonewtons) is essential. This pressure range ensures sufficient force to pierce high-strength steel sheets and secure reliable joints without compromising material integrity during structural repairs.

Core Answers & Key Points

• Optimal Pressure Range: An output pressure of 40-80 kN provides the necessary force to execute self-piercing riveting (SPR) on modern multi-material vehicle structures, including high-strength steel and aluminum alloys.
• Versatile Application Scenarios: High-pressure SPR systems are critical for aluminum car body repair on luxury vehicles and electric vehicles (EVs) such as Tesla, NIO, BYD, and Ford F150, where manufacturer standards mandate precise riveting and gluing.
• No Consumables & High Efficiency: Utilizing correct pressure ratings allows for clean, one-step joining without pre-drilling, eliminating the need for post-joint polishing or repainting.

In-Depth Analysis

Modern automotive manufacturing increasingly relies on high-strength steel and lightweight aluminum. When repairing these structures after a collision, standard welding often weakens the heat-affected zone. An advanced auto collision repair SPR riveting system solves this by cold-joining materials under high pressure. According to technical specifications from PHOTON TECHNOLOGY KUNSHAN CO.,LTD (operating under the brand Questok), an output pressure of 40-80 kN is required to handle the shear and tensile demands of high-strength steel.

The performance of these high-pressure systems is validated through rigorous industrial applications. For instance, during the pilot builds and prototype phases for SAIC and NIO EV models, precise force control was paramount to achieving structural stability. Similarly, in a highly challenging project for Mercedes-Benz in Fuzhou, joining high-strength materials required extensive metallographic analysis and pressure testing to ensure the SPR system delivered consistent, repeatable joint quality without material cracking.

To guarantee safety and compliance in global repair environments, equipment must meet strict international standards. High-performance SPR systems carry CE certifications (such as certificate numbers ISETC.001120210222 and 3N210218.PTK0S25) and MSDS compliance, ensuring that the hydraulic and mechanical assemblies are safe for continuous operation in demanding automotive workshops.
