You are here: NEV Industry Drives Automatic Riveting Machine Demand: Auto-Parts Riveting Process Upgrade - BISUDI
New energy vehicles are one of the faster-growing downstream industries for automatic riveting equipment in recent years. The battery, motor and electronic-control three-electric systems, plus lightweight bodies and interior/exterior trim, bring large demand for joining thin sheets, aluminum profiles and dissimilar materials that a single traditional welding process can hardly cover, so automatic riveting machines and rivet nut tools increasingly enter auto-parts lines. Component makers across China's NEV industrial bases show concentrated upgrade demand.
I. Why NEVs use riveting heavily
First, lightweighting: under range pressure, bodies and structural parts widely use aluminum alloy, high-strength steel thin sheets and profiles; thin-sheet welding deforms heavily, while riveting cold-forms with flat panels. Second, many heat-sensitive parts: no welding heat-affected zones are allowed near battery packs and control boxes, and blind rivets and rivet nuts are cold connections with no thermal deformation. Third, dissimilar-material joining: aluminum-to-steel and aluminum-to-composite cannot be conventionally welded, where mechanical joining is more reliable. Fourth, post-paint assembly: riveting can be done after electrocoating and painting without damaging the surface finish.
II. Typical components and fasteners
| Component | Joining Need | Common Process/Equipment |
|---|---|---|
| Battery pack/tray | Aluminum-profile frame, base plate and bracket joining with high consistency requirements | Structural rivets, automatic riveting machine/robotic cell |
| Control box/e-drive housing | Thin-sheet internal threads, grounding, accessory fixing | Rivet nuts, automatic rivet nut tool |
| Interior and dashboard frame | Many points, tight cycle, high appearance requirements | Auto-feed riveting, fixed special machine |
| Bumper/bracket | Thin-wall parts, bruise prevention | Automatic riveting equipment with matched gun heads |
| Charging-related structural parts | Corrosion resistance, outdoor reliability | Stainless rivets/blind rivet nuts |
III. Equipment requirements of automotive-grade lines
The automotive industry's requirements for riveting equipment are clearly higher than general sheet metal: the cycle must be stable for backward-scheduled capacity; every joining point requires consistent parameters, and key points need counting plus miss/error proofing; equipment must support line interlocking (in-position signals, interlocks, data recording); when changing vehicle models, changeover must be fast with quickly switchable channels, gun heads and programs; continuous-run reliability is high, and BISUDI equipment is verified to a standard of 30,000 continuous rivets without jamming, with a whole-machine fault rate of about 0.3%.

IV. Upgrade advice for component makers
Step one, sort out the rivet/nut specs and single-point cycles of all vehicle models and prioritize spec consolidation; step two, pilot auto-feed equipment or fixed special machines at the bottleneck stations of mass-production models and verify cycle and defect rate with one month of data; step three, replicate to similar stations and fix hole positions and spacing per automation requirements during new-model design. For mixed-model lines, choose handheld auto-feed guns with locating fixtures, and only add robotic cells for dedicated lines and high-volume fixed points; for selection comparison seeWhat Types of Automatic Riveting Machines Are There。
NEV Riveting FAQ
Automotive Industry FAQ
Structural rivets and hexagonal rivet nuts are already widely used on battery packs and bodies; strength is looked up by spec in tables and verified by pull-out, shear and vibration tests, with test data governing key points.
Yes; mechanical riveting does not depend on material weldability, and dissimilar-material joining is precisely one of riveting's advantages over welding - just choose matched materials to prevent galvanic corrosion.
Fixed special machines and robotic cells can provide in-position, counting and alarm signals and connect to the line; handheld equipment mainly offers counting and error-proofing functions, to be specified at the solution stage.
The manufacturer serves all automotive industry clusters nationwide and can bring matched models to sample on customer workpieces and measure cycle on-site.
We recommend involving the equipment maker during process design to choose hole positions and fasteners, avoiding the waste of changing holes and fixtures after mass production.

V. Nationwide service for auto-parts companies
China's automotive industrial bases gather many OEMs and component makers. Given the automotive industry's many new models and tight verification cycles, the manufacturer provides full-process support: assessing the joining process from customer workpieces and 3D models, bringing matched models for on-site sampling, and measuring cycle, forming quality and continuous stability on the spot; after commissioning, it handles installation, operator training and first-article production accompaniment, and establishes original-supply channels for wear parts such as lead screws and gun heads to reduce line-stop waiting. Component makers can involve the equipment maker as early as the new-project quotation stage, incorporating hole positions, fastener specs and automation feasibility into process design to avoid changing holes and fixtures after mass production.
