Project Introduction: Bus‑Bar Bending‑Forming Machine
Sep 22,2026
Copper bus‑bars are key conductive components widely used in new‑energy batteries, energy‑storage cabinets, high‑low‑voltage electrical equipment. Bending‑forming of copper bus‑bars is an essential working procedure for bus‑bar processing. Copper bus‑bar has good ductility, yet during bending‑forming it is prone to surface scratches, edge cracking, cross‑section distortion, spring‑back deformation and dimensional tolerance out‑of‑range. Conventional bending‑forming equipment has unstable pressing force, poor mold‑fitting accuracy, which easily causes bus‑bar wrinkling, cracking, uneven surface and inconsistent finished‑product dimensions.
The Haifei bus‑bar bending‑forming machine is specially developed for bus‑bar bending‑forming technical difficulties. It can complete feeding, positioning, multi‑angle bending‑forming and discharging of copper bus‑bars.
I Customer Background and Pain Points
One customer focuses on supporting production of various copper bus‑bars, laminated bus‑bars, new‑energy conductive connecting components. Its products are widely applied for new‑energy batteries, energy‑storage cabinets and high‑low‑voltage electrical equipment.
Production pain points of the original bending‑forming process:
1.Unstable mold‑closing pressure, poor fitting between mold and workpiece, bus‑bar prone to wrinkling, cracking and surface bruising.
2.Manual positioning adopted, positioning accuracy limited; spring‑back after bending leads to angle deviation and dimensional out‑of‑tolerance.
3.Bending‑forming of multi‑specification bus‑bars requires frequent mold replacement and manual adjustment, long change‑over time and low production efficiency.
4.Heavy manual‑dependence, unstable batch quality, process parameters cannot be stored and production data lack traceability.
II Customer Requirements
1.Optimize bus‑bar bending‑forming process, reduce surface scratches, cracking, wrinkling and spring‑back deformation defects.
2.Realize precise positioning and stable pressing‑force control, guarantee bending‑angle accuracy and finished‑product dimensional consistency.
3.Adapt to multi‑specification bus‑bar production, simplify mold‑changing and adjustment steps, shorten product change‑over cycle.
4.Reduce manual intervention, support parameter storage and recall, realize traceable production data, ensure long‑time continuous stable equipment operation.
III Custom‑Developed Solutions
Targeting customer requirements, the dedicated R&D team repeatedly tuned and optimized schemes in view of bus‑bar bending‑forming difficulties, to ensure deliverables fit customer demands. Details are as follows:
1.Process verification: Carry out multiple groups of exclusive bending‑forming process tests for copper bus‑bars of different thickness, width and bending‑angle requirements.
2.Equipment selection: Adopt Haifei bus‑bar bending‑forming machine. Stable pressing‑force output and high‑precision mold matching effectively restrain bus‑bar wrinkling, cracking and spring‑back deformation. Bending angle and dimension are stable and consistent.
3.Structural design: The equipment is equipped with high‑precision positioning mechanism. Custom‑built exclusive bending molds for different bus‑bar specifications realize rapid mold switching. Uniform stress during bending reduces surface scratch and cross‑section distortion.
4.Core Advantages
Excellent forming quality: low scratch, no cracking, small spring‑back.
High‑precision output: stable angle, consistent dimension.
Efficient production: quick specification change‑over, labor‑saving.
IV Delivery, After‑Sales Service and Customer Feedback
Pre‑acceptance and equipment inspection were carried out. Continuous trial operation maintains stable product qualified rate. After commissioning, all original production pain points of the customer are fully resolved. Timely, professional and thoughtful after‑sales service earns positive customer comments.
