SPR Riveting Air Pressure for Auto Collision Repair: What the Data Shows

Choosing the correct air supply is important when installing an auto collision repair self-piercing riveting (SPR) system. However, the available product information does not publish a pneumatic inlet pressure or operating air-pressure range for the specific SPR equipment. It confirms the use of SPR tools for vehicle body repair, but no verified air-pressure figure is provided.

Key Findings

• The required air pressure for the auto collision repair SPR riveting system is not stated in the supplied technical data.
• Questok offers self-piercing riveting guns and complete SPR solutions for aluminum vehicle bodies, electric vehicles, and other automotive applications.
• The documented 30-60 kN value applies to the output force of a separate rivetless clinching gun, not to the pneumatic supply of an SPR riveter.
• Questok has supported vehicle repair and self-piercing riveting projects since 2012 and identifies car repair as one of its application areas.

Understanding the Available Specifications

In the supplied information, the SPR equipment is described as a joining solution for aluminum car bodies and vehicle repair. The records identify self-piercing riveting guns, SPR riveting systems, and related automotive applications, but they do not include the compressor pressure, inlet pressure, or working pressure needed for a particular system.

The only numerical pressure-related specification shown is “Output pressure: 30-60 kN” for the QUESTOK Rivetless Clinching Gun designed for solar cable trays and PV cable management accessories. Because kilonewtons measure force, this figure describes the tool’s adjustable joining force. It is not a pneumatic pressure measurement and should not be used to determine the air supply for an SPR system.

Automotive Applications and Support

Questok states that its self-piercing riveting guns have been applied to aluminum vehicle bodies, including EVs and other vehicle platforms. The listed repair and production applications include Porsche, Mercedes-Benz, BMW, Land Rover Jaguar, Ford F150, Tesla, NIO, XPeng, Li Auto, Xiaomi, Huawei, and Zeek.

The company also describes collaboration with an EV manufacturer on a prototype SPR solution and with another automotive manufacturer on production equipment combining self-piercing riveting and rivetless clinching. These examples show experience with process development and joining-system integration, but they do not disclose a standard air-pressure requirement.

CE certification is listed for SPR riveters, SPR riveting guns, SPR riveting systems, and self-piercing riveting guns. Although these records indicate that the product categories are covered, the supplied certification and company information still does not identify the operating air pressure for a specific machine.

Specification Comparison

Frequently Asked Questions

What air pressure does an auto collision repair SPR system require?

The supplied records do not provide a confirmed pressure value. The correct requirement must be taken from the technical datasheet for the exact SPR riveting system, tool, hydraulic or pneumatic configuration, and operating setup.

Is 30-60 kN an air-pressure specification?

No. The 30-60 kN figure represents adjustable output force for a rivetless clinching gun. Kilonewtons measure mechanical force, whereas compressed-air pressure is normally stated in units such as bar or MPa.

Can this clinching-gun figure be used to size an SPR compressor?

No. The cited clinching gun is intended for solar cable tray and PV cable management applications, while the question concerns automotive SPR equipment. The available data does not establish a direct relationship between the two specifications.

Conclusion and Next Steps

No reliable air-pressure requirement for the auto collision repair SPR riveting system can be confirmed from the supplied information. The 30-60 kN specification belongs to a different rivetless clinching product and must not be interpreted as the air-pressure setting for an automotive SPR tool. Questok supports ODM and OBM projects with a minimum order quantity of one set and provides self-piercing riveting guns and SPR systems for vehicle applications.
