SPR Riveting Machine for Compact Busbar Trunking Shell Assembly
Busbar trunking (bus duct) is critical equipment for low-voltage power distribution. Busbar manufacturers need fast, stable sealing assembly for aluminum or galvanized steel outer shells. Welding damages galvanized layers and causes thermal deformation; bolt fastening slows down production and carries vibration-loosening risks. SPR riveting machines become the preferred solution.
An automatic SPR riveting machine with auto rivet feeder completes cold joining in one stroke. SPR rivets pierce the outer sheet and flare inside the bottom plate, forming sealed mechanical lock joints. No pre-drilling, no sparks, no heat damage to shell coatings.
Good sealing performance helps maintain the busbar’s IP protection rating. Dacromet coated SPR rivets provide long-term anti-corrosion ability for indoor and outdoor power distribution installations. Manufacturers can choose bulk SPR rivets or tape-fed reel rivets to match different production lines.
SPR machines are used for compact sandwich busway, enclosed bus duct and power cabinet sheet metal assembly. The finished rivet points are neat, with no post-processing required.
This technology reduces deburring and rework work, improves line speed and lowers reject rates for mass busbar production.
Power equipment manufacturers upgrading their production lines should evaluate SPR riveting systems for busbar shell fabrication.
