Beiene Global Pte. Ltd.
Busbar processing machinery for switchgear and busway manufacturing
Beiene builds CNC punching, shearing, bending, chamfering and busway machinery for panel builders, busway manufacturers, transformer plants and power-distribution suppliers. Machines are delivered fully assembled and commissioned, with 3D programming software, nesting and remote diagnostics included.
Machines by operation
Nine machine families and sixteen models, from a 300 kN all-in-one to an 800 kN processing centre running six-metre bar at 200 hits per minute.
Busbar processing centres
Fully automatic punching and shearing centres for copper and aluminium busbar, with 800 kN on both units, 24 to 36 tool stations, multi-bar loading and integrated nesting.
2 models
Punching and shearing machines
CNC punching and shearing machines from 400 to 800 kN, for bar up to 6000 × 300 × 20 mm, with German in-line die libraries and three shear modes.
3 models
Bending machines
Three-dimensional bending machines rated 400 kN, holding ±0.1° with electronic springback compensation, in hybrid hydraulic and pure servo configurations.
2 models
All-in-one machines
Single machines combining punching, shearing, bending, twisting and embossing, rated 300 to 600 kN, with optional six or eight station turrets.
4 models
Chamfering and edge-machining centres
Three-axis arc machining centres with automatic tool change, producing edge radii in both the width and thickness directions in one setup.
1 model
Deburring and polishing machines
Two-stage grinding machines for bar from 0.5 to 50 mm thick, combining burr removal with oxide removal ahead of plating.
1 model
Busduct and busway machines
Sawing, joggling and flaring centres for busway housings, and dedicated fish plate punching, stretching and cutting to better than ±0.1 mm/m.
2 models
Handling and storage
Manual transport trolleys through to automatic rail-guided storage systems that feed the processing centre and share stock records with the nesting software.
3 models
Software
Three-dimensional design, whole-project nesting, oddment reuse and machine-side job management, with MES functions built in rather than supplied as an addition.
3 models
Start from the process
Each operation in the busbar chain, what it demands of the machine, and the failure modes it produces when it is set wrong.
Busbar punching
Tonnage, clearance, tool geometry and slug control — the operation that determines both hole quality and tooling cost.
Cutting and shearing
Shear against saw, burr direction, length tolerance and the scrap that offcut strategy either creates or avoids.
Busbar bending
Flatwise and edgewise forming, minimum radius by temper, springback, tooling marks and bend-sequence planning.
Busbar twisting
Twist length, section warping and when a twist is the right answer instead of an edgewise bend.
Embossing and coining
Joint-area forming, why it gets specified, and what it does to real contact area.
Chamfering and edge rounding
Edge radius for field uniformity and insulation adhesion — not cosmetics.
Deburring and polishing
Burr acceptance, oxide removal before plating, and the surface finish a bolted joint requires.
Joggling and flaring
Offsetting stacked phase bars into a common joint plane, and forming the flare that completes the busway joint.
Built for the end product
Bar envelope, tolerance and throughput requirements differ by product. These pages set out what each sector specifies.
Switchgear and panel builders
High-mix, drawing-driven work where engineering changes arrive weekly and lead time decides the order.
Busduct and busway manufacturers
Long runs, repeated joints, and a joint plane that has to be right along six metres of housing.
Data centre power distribution
Rack densities have moved from 5–15 kW to 60 kW and beyond, and the busway feeding them has to be fabricated to match.
EV charging and power electronics
Thin gauge, tight tolerance, high mix, and insulation that will not forgive a sharp edge.
Transformer manufacturing
Heavy sections, tap connections and a stable, specification-driven buyer that most machine builders underserve.
Renewables and energy storage
Battery and inverter busbar work, where volume ramps fast and changeover time is the constraint.
Company
A group, not a single office
A Singapore holding company, with a research and development centre in Hannover, local sales and service in North America, and machines in service in more than 60 countries.
Beiene builds intelligent busbar processing machinery. The group's engineering lineage traces to a hydraulics research institute founded in 1955; today its machines are in service with more than 1,000 customers in over 60 countries.

Punching
Punch-to-die clearance for copper and aluminium busbar
How to set punch-to-die clearance per side on 6-20 mm copper and aluminium bar, read the sheared edge, and specify burr height on the drawing.

Bending
Springback compensation in busbar bending
How to predict and cancel springback in copper busbar bending: the governing ratios, a worked calculation, overbend by EN 13601 temper, and CNC offset tables.

Standards
Busbar hole patterns and what DIN 43673-1 actually specifies
What the four pages of DIN 43673-1 govern, the engineering behind edge distance, pitch and hole diameter, and why DIN 46433 is not a busbar standard.
