Busbar Leveling Machine – Micron-Level Flatness for Conductivity

2025-07-23 click:15

Surface flatness impacts contact and heat transfer – 0.1mm protrusions cause overheating. Shandong Bolt's machine achieves ≤0.05mm/m flatness via 12-roller processing.

Progressive Leveling

  • Pre-press: 5-10kgf/cm² removes transport warping.

  • Main level: 10-30kgf/cm² CNC-adjusted pressure shapes 0.5-10mm busbars.

  • Finish: Polishing reduces roughness from Ra3.2μm to Ra1.6μm.

1-10m/min adjustable speed handles 80-200m/hour.

Material Protection

  • Copper (≥200MPa): 20-30kgf/cm², 3-5m/min.

  • Aluminum (≥110MPa): 10-20kgf/cm² with protective film.

50μm chrome-plated rollers prevent contamination.

Downstream Benefits

New energy inverter line results: 95%+ heat sink contact, 20% lower resistance, 8℃ cooler operation. Reduces bending scrap from 5% to 0.8%. Integrates into automated lines with auto-adjustment.
