III. Key Functional Differences
303 CNC Three-in-One’s Unique Advantages:
1. Vertical bending processing: Can perform vertical bending, essential for irregular copper busbars in high and low voltage switchgear. DHY has no vertical bending function.
2. CNC program storage: The bending unit has a memory function; the system automatically remembers the last set of parameter data, eliminating the need to re-enter the data.
3. Laser positioning + Multi-directional stop: Precise positioning for punching and cutting, reducing scribing steps.
4. Three-station parallel operation: Punching, shearing, and folding operate independently, increasing production capacity by 2-3 times for bulk orders.
5. Thickened body and heavy-duty hydraulic cylinder: 15mm thick copper busbar, high-current main busbar without pressure, burr-free cut surfaces, eliminating grinding steps.
6. Optional addition of embossing, chamfering, twisting, and beveling extension stations, providing one-stop processing for complete sets of equipment.
DHY-200 Portable Model Unique Advantages:
1. On-site construction: On-site modification of power distribution cabinets, temporary copper busbars at construction sites, and emergency repairs, eliminating the need to transport copper busbars back to the workshop.
2. 220V universal power supply: Can be powered by construction site power strips and temporary generators, eliminating the need for industrial three-phase power.
3. Split and lightweight: Easily transported by vans and trucks, suitable for small workshops and on-site maintenance.
- Low investment cost: The price of the entire machine is only about 1/4 of the 303 machine tool, reducing financial pressure.

DHY-200 Obvious Shortcomings:
1. No vertical bending capability; only simple flat bending is possible, limiting the processing of complex cabinet copper busbars.
2. Single-head alternating operation results in extremely low batch processing efficiency.
3. No CNC control; dimensions and bending angles are entirely manual, leading to poor consistency in batch products and frequent rework.
4. Small hydraulic pump; prolonged processing causes oil temperature to rise and pressure to drop, making thick busbar processing difficult.
5. Short bending stroke; unable to perform multi-segment continuous bending or deep U-bends.
IV. Applicable Scenarios: The [303 CNC Three-in-One Copper Busbar Machine] is suitable for:
1. Regular mass production factories producing high and low voltage complete sets of equipment, processing more than 50 sets of copper busbars per day.
2. Need for batch standardized copper busbars, pursuing uniform precision and reducing rework.
3. Frequently processing irregularly shaped copper busbars: vertical bending, multi-segment bending, and thick main busbars.
4. Fixed workstations in workshops with 380V power. Industrial power supply, long-term stable production
5. Export complete set factory, large-volume switch cabinet OEM, pursuing processing efficiency
303 CNC finished copper busbar processing Choose the [DHY-200 Portable Copper Busbar Machine], suitable for:
1. Power on-site emergency repair, temporary modification of construction site distribution cabinets, after-sales maintenance
2. Small shops, repair shops, with scattered orders and small quantities, occasionally processing copper busbars
3. No fixed processing workshop, requiring frequent on-site construction
4. Limited budget, only doing simple flat bending, punching, and cutting, not complex vertical bending parts
5. Temporary projects, outdoor projects, only 220V civilian power supply
V. Procurement Selection Summary in One Sentence
1. Mass production complete set factory, pursuing precision and efficiency, fixed workshop processing → 303 CNC three-in-one machine can do vertical bending, three stations can work simultaneously, CNC standardization, long-term mass production and fast return on investment.
2. Construction site, maintenance and emergency repair, small-batch sporadic processing, low budget, need for mobile operation → DHY-200 Portable Model. Lightweight and easy to move, universal 220V, but only suitable for simple processing and not for large-scale standardized production.
