Power Distribution Cabinet · Electrical-Equipment Automatic Riveting Machine · Switchgear / Distribution Box / Cable Tray Riveting Solutions

Many manufacturers supply electrical switchgear assemblies, distribution boxes, switchgear, ring-main units, control boxes, cable trays and busbars, and battery-swap/charging cabinets. Cabinets commonly use thin sheet, powder-coated panels and aluminum-profile/galvanized frames, requiring many joints and removable internal threads on doors, mounting plates and frames. Traditional tapping strips threads and welded nuts distort and damage the coated surface. CHANRUI's automatic rivet nut tool forms M3-M12 rivet nuts in one stroke and, together with dual-gun riveting machines, completes cabinet assembly; it can be retrofitted in place after powder coating - a mature solution the switchgear industry uses to improve efficiency and appearance, with free on-site trials for power-cabinet enterprises nationwide.

Solution Highlights

Frames and doors use a rivet nut tool plus a dual-gun riveting machine combination; coated parts with on-site hole changes get rivet nuts retrofitted directly; cable trays and thick-plate brackets use high-force models.

Anonymized case: a switchgear assembly factory

Mounting plates and doors originally used tapping plus bolts, with frequent stripping rework and post-coating hole filling. After switching to rivet nuts and deploying 2 automatic rivet nut tools and 1 high-force riveting machine, frame and door operations merged into the assembly line, repair-welding/grinding labor was largely removed, and manual labor per cabinet fell by about one third.

FAQ

Q1: Is it still possible to retrofit cabinets after powder coating?

Yes. Rivet nuts are cold-formed; on coated parts, simply set them into pre-made holes - no welding, no damage to the coated surface - ideal for on-site hole changes and rework.

Q2: Is the pull force sufficient for large M10/M12 sizes?

Dual-motor high-force models cover M10-M12 rivet nuts and aluminum-profile beams; during the trial we test on site using the thickest plate, and provide a gantry solution if needed.

Q3: Can power-cabinet makers arrange an on-site trial?

Yes. For electrical switchgear enterprises nationwide, an engineer can bring a machine to your factory and run samples on real cabinets; usually free of charge.

Power-cabinet / electrical customers: reserve sampling

Provide cabinet drawings, plate thickness and fastener specs; an engineer will bring a machine on site to test rivet-nut pull force, stripping rate and labor time, and provide a selection quotation.
