You are here: Why the NEV Industry Is Lifting Automatic Riveting Machine Demand: Auto-Parts Riveting Process Upgrade - CHANRUI
New energy vehicles rank among the fastest-growing downstream industries for automatic riveting equipment in recent years. The battery, motor and electronic-control three-electric systems, together with lightweight bodies and interior/exterior trim, create large demand for joining thin sheets, aluminum profiles and dissimilar materials that a single traditional welding process can barely cover, so automatic riveting machines and rivet nut tools are increasingly entering auto-parts lines. Component makers across China's NEV industrial bases reveal concentrated upgrade demand.
I. Why NEVs rely heavily on riveting
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, whereas riveting cold-forms with flat panels. Second, many heat-sensitive components: no welding heat-affected zones may occur near battery packs and control boxes, and blind rivets and rivet nuts are cold connections with no thermal deformation. Third, joining of dissimilar materials: aluminum-to-steel and aluminum-to-composite cannot be conventionally welded, where mechanical joining proves more reliable. Fourth, post-coating assembly: riveting can be carried out after electrocoating and painting without damaging the surface finish.
II. Typical parts and fasteners
| Part | Joining requirement | Typical 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 and accessory fixing | Rivet nuts, automatic rivet nut tool |
| Interior trim and dashboard frame | Many points, tight cycle, high appearance demands | Auto-feed riveting, fixed special-purpose machine |
| Bumper / bracket | Thin-wall parts, bruise-free | Automatic riveting equipment fitted with matched gun heads |
| Charging-system structural parts | Corrosion resistance, outdoor dependability | Stainless rivets / blind rivet nuts |
III. Equipment requirements for automotive-grade lines
The automotive industry's requirements for riveting equipment are markedly higher than those for general sheet metal: the cycle must stay stable to support 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 vehicle models change, changeover must be fast with quickly switchable channels, gun heads and programs; continuous-run reliability is high, and CHANRUI 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 recommendations for component makers
Step one, work 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 against one month of data; step three, roll out 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-sector FAQ
Structural rivets and hexagonal rivet nuts are already in wide use on battery packs and bodies; strength is looked up by spec in tables and confirmed 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 exactly one of riveting's advantages over welding - just choose matched materials to avoid 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 defined at the solution stage.
The manufacturer serves every automotive industry cluster nationwide and can bring matched models to sample on customer workpieces and measure the cycle on-site.
We recommend involving the equipment maker during process design to choose hole positions and fasteners, avoiding the waste of reworking holes and fixtures after mass production.
