Automotive Industry
The automotive industry covers three core scenarios: body welding, coating pre-treatment and power battery housing manufacturing, with base materials including cold-rolled steel, galvanized steel, aluminum alloy and new energy battery shell materials.
Welding processes on car bodies create weld beads, spatter and thermal discoloration. Rust, oil and oxide layers must be fully removed before coating to guarantee adhesion of electrophoretic paint and topcoat. After stamping and welding, battery housings require grinding of weld seams, burrs and drawing marks to prevent seal failure, insulation film damage and stress concentration.
Lean Abrasives’s high-precision sanding belts are suitable for rough grinding and surface blending on car body panels and battery housing continuous lines. Coarse grit belts remove weld beads and heavy oxide quickly, while fine grit belts smooth weld seams and form a reliable anchor profile for coating.
Our flap wheels, sanding discs and abrasive discs are used for spot grinding on body frames, housing edges and irregular welds, performing well in narrow spaces and complex contours.Polishing wheels are adopted for fine finishing of housing surfaces. Sanding paper and scouring pads support manual touch-up in rework stations.
