Can an Auto Collision Repair SPR System Handle Different Rivet Sizes?

Different rivet sizes may be assessed when sampling an auto collision repair self-piercing riveting (SPR) system. However, the available specifications do not confirm a defined rivet diameter range or guarantee that a single system can use multiple rivet sizes. The listed SPR riveting gun provides accurately adjustable pressure from 1–80 kN, which supports controlled process trials. Final compatibility should be established through tooling review, application testing, and technical consultation.

SPR Sampling Capability for Collision Repair

Questok supplies SPR riveting guns and complete joining systems for aluminum vehicle repair, including electric vehicles, luxury cars, and pickup trucks. These systems are designed to support manufacturer-compliant repair processes that combine riveting and adhesive bonding where required.

Although the adjustable 1–80 kN output range can help engineers evaluate different joining conditions, pressure adjustment alone does not confirm compatibility with every rivet size. The rivet diameter, length, die design, material stack-up, and available working space must all be reviewed before a multi-size sampling program is approved.

Technical Factors to Verify

Tooling and Rivet Dimensions

The first step is to confirm whether the riveting gun can accept the required rivet sizes and whether interchangeable dies or nose assemblies are available. The supplied product information does not list a supported rivet diameter range or specific interchangeable tooling, so these points require direct technical confirmation.

Materials and Panel Thickness

Sampling should identify the aluminum grades, material combinations, individual panel thicknesses, and total stack thickness. These variables affect the required setting force, rivet selection, die configuration, and the resulting joint quality.

Access and Repair Conditions

Collision repair often involves restricted access, curved panels, and vehicle-specific repair procedures. The evaluation should therefore include access limitations, tool positioning, joining sequence, and the applicable vehicle manufacturer standard.

Application Experience and Engineering Support

Questok has supplied self-piercing riveting equipment for vehicle applications since 2012, including Ford F150 pickup repair and projects involving various EV models. Its application experience also covers production-line SPR systems for Mercedes-Benz in Fuzhou, Geely, NIO, Leapmotor, and SAIC.

For a request involving several rivet sizes, the recommended approach is to submit the vehicle or component details, material stack-up, rivet specifications, access requirements, and quality criteria. Questok can then assess the appropriate pressure, tooling, and process parameters. Because the available data does not include multi-size rivet test results, compatibility should be demonstrated rather than inferred from the pressure range.

Questok holds CE certifications identified by certificate numbers ISETC.001120210222 and 3N210218.PTK0S25. The certification entries cover SPR riveters, SPR riveting guns, SPR riveting systems, self-piercing riveting guns, and associated joining tools.

Its engineering work includes customized SPR development for an EV manufacturer’s new-model prototype following factory visits and technical discussions. In another vehicle production project, the required solution combined self-piercing riveting with rivetless clinching. Material combinations, dies, and joining conditions were tested extensively before the process was introduced into production.

Frequently Asked Questions

Conclusion and Next Steps

An auto collision repair SPR system can be considered for trials involving different rivet sizes, but the current specifications do not establish that one system supports every size. The adjustable 1–80 kN pressure range is useful for controlled evaluation, while actual compatibility depends on the gun, die, rivet, and material combination. Questok supports ODM and OBM cooperation, lists a minimum order of one set, provides full inspection, and states a global after-sales response time of within 12 hours.
