CLEAN ENERGY PRODUCTION PHYSICS
Overcoming EV Busbar Processing Obstacles
How our low-friction polymer tooling, proportional hydraulics, and compact split-block benders solve battery pack and PV inverter busbar production issues.
CHALLENGE
Insulation Sleeve Tearing During Bending
Impact: Standard bending dies pinch and tear heat-shrinkable PVC/PET insulation sleeves on EV busbars, causing dielectric isolation failures that scrap expensive finished parts.
DH CNC SOLUTION: INSULATION-SAFE SPECIALTY TOOLING
We factory-design custom R-angle bending dies with low-friction polymer contact inserts. This allows smooth material flow during the bending cycle without tearing the insulation jacket.
CHALLENGE
Laminated Copper Foil Deformation
Impact: Clamping and shearing multi-layered flexible copper foils (typically 0.1mm layers) under standard high-pressure hydraulic shear clamps crushes and tears the edges, ruining the laminations.
DH CNC SOLUTION: LOW-PRESSURE SERVO PROPORTIONAL CLAMPING
Our workstations feature custom-calibrated proportional hydraulic control packages. This allows operators to program precise micro-clamp settings to process sensitive foil packages without edge collapse.
CHALLENGE
Extremely Tight Flange U-Bending
Impact: EV battery cell connectors require ultra-compact U-bends (down to 40mm inner flange width). Standard bending backplates clash, making standard automated processing impossible.
DH CNC SOLUTION: SPLIT-BLOCK CUSTOM BENDING TOOLING
We supply compact split-block bending modules designed for tight clearance profiles. This allows the bender to retract completely without standard collision paths, executing tight bends in single runs.
