HEAVY DISTRIBUTION ENGINEERING
Optimizing Heavy-Duty Busbar Fabrication
How our heavy industrial framing, specialized mold sets, and CAD-CAM integrations solve B2B power busduct fabrication problems.
CHALLENGE
High Copper Scrap Waste
Impact: Traditional double-cut shears and manual sheet markings generate 12-15% copper waste on expensive 6-meter T2 copper busbars, losing thousands in raw material costs per month.
DH CNC SOLUTION: 3D CAD/CAM NESTING INTEGRATION
Our flagship BP-60 workstation integrates custom 3D nesting algorithms. It imports SolidWorks/AutoCAD DXF files directly, automatically arranges hole layouts, and utilizes shared-edge shearing to limit waste to under 3%.
CHALLENGE
Extreme Bending Springback on Thick Bars
Impact: 15mm or 16mm thick copper busbars experience immense springback forces, causing manual bending angles to fluctuate by ±1.5° and requiring costly and slow manual correction.
DH CNC SOLUTION: CLOSED-LOOP SERVO PROPORTIONAL BENDING
Equipped with high-resolution German linear encoders and Atos proportional valves, our closed-loop bending station reads real-time elastic return and performs auto over-bending compensation to guarantee ±0.2° accuracy.
CHALLENGE
Complex Twisting & Offsetting Requirements
Impact: Transformer output terminals and heavy busway trunking systems require complex 90-degree twist bends and double offset Z-bends that damage standard folding tooling.
DH CNC SOLUTION: SPECIALIZED HARDENED DIE PACKAGES
We design and factory-supply custom-hardened steel twisting blocks and close-coupled Z-bend dies, allowing operators to execute precise twist and offset bends in single, continuous cycles.
