ZERO WORKPIECE TRANSFER FLOW

INTERACTIVE 3-IN-1 WORKFLOW DEMONSTRATION

Discover how the DH303-8P delivers rapid batch processing across three completely independent stations, avoiding time-wasting tool setups.

1. PUNCHING STAGE: 8-STATION TURRET

The multi-station turret structure avoids frequent die changes. Featuring 7 punching and 1 embossing die sets configured simultaneously in a thick ductile iron index head, reducing setup delays to zero.

2. SHEARING STAGE: ZERO-WASTE SINGLE-CUT

Dual column guide shearing frame delivers vertical downward force. Zero-waste single-cut mechanism completely eliminates copper off-cut scrap slivers, ensuring perfectly straight, burr-free edges.

3. BENDING STAGE: DUAL HMI STROKE CALIBRATION

Ductile iron open-frame bending unit provides a full 360° visibility. Siemens PLC registers linear travel values, calculating springback angles automatically to maintain high ±0.5° verticality tolerances.

How Does DH CNC Solve Common 3-in-1 Busbar Processing Production Bottlenecks?

How DH CNC drives multi-operator performance and eases blanking calculations on the shop Floor.

PAIN POINT: System Pressure Drop During Simultaneous Multi-Operator Use

Standard entry-level 3-in-1 machines share a single or dual hydraulic pump. When three operators attempt to punch, shear, and bend at the same time, fluid pressure collapses, stalling the machine and risking pump burnout.

DH CNC SOLUTION

3 Independent Pumps & Motors. The DH303-8P is designed with a robust triple-hydraulic circuit (3×31.5 MPa) powered by 4 independent motors. Three operators can work simultaneously at full capacity with zero pressure interference.

PAIN POINT: Dependence on Highly Skilled Operators for Blanking Calculations

Calculating the flat blanking length of copper bars before bending requires complex trigonometry to offset thickness deformation. Manual math errors lead to discarded copper and slower run times.

DH CNC SOLUTION

Smart Touchscreen HMI. The integrated Siemens HMI features automated blanking calculations. Operators simply enter drawing specifications (lengths L1-L4 and target angles), and the system automatically calculates the flat layout, punch positions, and bending strokes.

PAIN POINT: Poor Workpiece Visibility & High Swap Times on Closed Benders

Standard closed-type bending units (with top bars and screws) block the operator's view of the bend point. Aligning markings is difficult, and swapping dies takes 15-20 minutes, reducing custom batch throughput.

DH CNC SOLUTION

Ductile Iron Open-Type Bending. Our bending unit features an open cast ductile iron frame. It provides full 360° visibility for easy alignment and allows tooling swaps for flat, vertical, or U-bends in under 2 minutes.

What Is the Operator Learning Curve, ROI, and Global Application Scope of DH303-8P?

An engineering-focused evaluation of the DH303-8P 3-in-1 busbar processor's operational workflow, tooling economics, and regional voltage configurations.

Simultaneous Workstations & HMI Simplicity

Standard 3-in-1 multi-stations often share a single hydraulic circuit, causing pressure drops and forcing operators to wait. The DH303-8P workstation features three independent hydraulic pump and motor units (3×31.5 MPa). Bending, punching, and cutting stations operate simultaneously and at full speed, eliminating assembly line bottlenecks.

The built-in HMI touchscreen simplifies setup. Operators input copper busbar thickness and desired bend angles, and the system automatically calculates coordinates and stroke positions. Setup time and manual calculations are reduced to near zero, shortening the operator learning curve to under 4 hours.

45% Capital Savings & Space Optimization

Purchasing individual standalone bending, punching, and shearing machines increases equipment acquisition costs, footprint, and maintenance overhead. The DH303-8P delivers three dedicated, industrial-grade stations on a single compact footprint, saving up to 45% in capital expenditure and freeing up floor space.

The unified, heavy-duty cast monoblock frame prevents alignment drift during transport. This ensures perfect calibration out of the box and saves $3,000–$5,000 in third-party technician calibration fees upon delivery.

Switchgear Enclosures & Grid Compatibility

Perfect for low-voltage switchboard assembly, high/low voltage switchgear enclosures, custom control panels, and transformer winding workshops. It cuts and punches copper busbar stock up to 12mm thick with absolute repeatability.

Every system is custom-configured at our factory to match your local power infrastructure, pre-wiring motors and starters for 220V/440V 60Hz (Mexico & LATAM), 480V 60Hz (USA & Canada), and 380V/400V 50Hz (Europe, Asia, Middle East). Shipped in seaworthy vacuum rust-barrier bags inside reinforced non-fumigation wood crates.
