Automatic Ring Making & Welding Machine Economic Version


  • Model: R-6-300 E-Series
  • Input voltage: 380V(3-phase) or custom
  • Power frequency: 50/60Hz
  • Instant power during welding: 15KVA(for 4mm wire)
  • Instant power during forming: 2KVA
  • Wire thickness: 2-5mm
  • Max ring diameter: 300mm(can be customized to 600mm)
  • Min ring diameter: 70mm(can be customized to 50mm)
  • Ring perimeter tolerance: 0.5mm
  • Cooling: Natural cooling
  • Air flow required: 250L/min
  • Air pressure: 0.6-0.8MPa
  • Throughput: about 1560pcs/hr(for ring diameter 150mm)
  • Weight: 1000KGS


  • R-6-300 E-Series is not equipped with digital regulation of ring sizes, max wire thickness it can work with is 5mm.
  • High precision: intelligent "S" shape speed curve, the encoder and the motor form a closed-loop wire feeding control system, secure a diameter tolerance less than 0.16mm, eventually solve the ring precision issues inherent in the traditional mechanical or hydraulic ring making machines.
  • High stability: wire feeding unit is driven by two motors directly without gears, belts or other transmission parts which would get less precise due to wear-out.
  • Easy operation: ring size is adjusted by turning the wheels, much easier than traditional mechanical or hydraulic machines.
  • Automatic ring welding: worker attendance is not required during machine operation.
  • Compatible welding: capable of welding low, medium and high carbon steel, spring steel, galvanized steel.
