New Energy · Li-ion Storage Automatic Riveting Machine · Battery Trays / Storage Cabinets / Inverter Riveting Solutions
As new-energy installed capacity and the storage market expand, demand for battery trays, PACK module brackets, storage and battery-swap/charging cabinet frames, PV inverter enclosures and PV brackets is growing rapidly. These workpieces are largely made of aluminum profiles, aluminum sheet and galvanized sheet, and call for sealed, reliable, removable and rust-proof blind-rivet and rivet-nut joints. CHANRUI supplies robotic/gantry riveting stations, dual-motor rivet nut tools and dual-gun riveting machines, with free on-site trials for new-energy and storage enterprises nationwide.
Typical Workpieces & Solutions
| Workpiece | Typical Fasteners | Suggested Solution |
|---|---|---|
| Battery trays, PACK brackets | M5-M10 rivet nuts, Ø4.8-6.4 rivets | Robotic / gantry riveting station |
| Storage cabinets, battery-swap/charging cabinet frames | M6-M12 rivet nuts | Rivet nut tool + dual-gun riveting machine |
| PV inverters, outdoor cabinets | Waterproof rivets, stainless-steel parts | Stainless-steel-specific / dual-gun model |
| PV brackets, combiner boxes | Thick plate / square tube, outdoor rust-proof | High-pull-force riveting machine |
New-energy Joining Priorities
| Focus point | Key points | CHANRUI Method |
|---|---|---|
| Sealed & waterproof | Strict requirements apply to outdoor and battery parts | Sealed rivet + structural adhesive combination verified |
| Dissimilar metals | Prevent galvanic corrosion within aluminum/steel joints | Isolation during selection and matched rivet material |
| Reliable internal threads | Tapping aluminum is prone to stripping | Rivet nuts cold-formed, repeatedly removable |
| Mass-production error-proofing | Missed rivets can affect safety | Count to target, IO to MES |
Solution Overview
Mass-production trays rely on robotic/gantry stations with sealing and pull-off verification; storage and battery-swap/charging cabinets adopt handheld dual-motor rivet nut tools; outdoor cabinets and PV brackets run on waterproof/stainless and high-pull-force models.
Storage and battery-swap/charging cabinet frames originally depended mainly on tapping plus bolts, with frequent thread stripping and on-site rework. After introducing 3 dual-motor rivet nut tools and 2 dual-gun riveting machines, internal threads in frames and doors were formed in one stroke and are repeatedly removable, labor per cabinet dropped by about one third, and complaints over outdoor-cabinet waterproofing and rust fell.
FAQ
Specs are selected by cross-section wall thickness with pull-off verification; sealing surfaces are achieved through a combination of structural adhesive, sealing rings and riveting, verified as a whole against your process during the trial.
Dual-motor high-force models cover M10-M12 rivet nuts and aluminum profiles; during the trial we test on site with the thickest plate and largest size, using a robotic/gantry station when needed.
We use stainless-steel or waterproof rivets with matched rivet nuts, plus aluminum/steel isolation; during the trial we verify corrosion protection and waterproofing against outdoor conditions.
