It is an automatic tube-shrinking machine/accessory designed for furniture applications such as chair and sofa legs. It performs fast, precise tube contracting (shrinking) to alter end diameters for assembly or finishing.
It can process a variety of metals including brass/copper, alloys, stainless steel, aluminum/aluminium alloy, and carbon steel.
Maximum shrinking capacity by diameter is 219 mm and maximum material thickness is 10 mm.
The maximum tube contracting length is 900 mm.
The machine's rated power is 5.5 kW. Specific electrical supply details (voltage, phase, breaker size) are model dependent—consult the technical/manual or contact the supplier for exact requirements.
Typical tube contracting cycle time ranges from 1 to 3 seconds, depending on material and job parameters.
Core components include the engine, bearings, gearbox, motor, gears and pump.
Unit weight is approximately 1000 kg. Production/supply ability is listed at 20 sets per week.
The product features automatic operation for fast and efficient tube contracting. Some set-up and supervision by an operator is typically required; exact automation level (PLC controls, program modes) depends on the model/configuration.
Prepare a stable, level floor capable of supporting the ~1000 kg weight. You will need appropriate electrical service for the 5.5 kW motor and access for lifting equipment (crane/forklift) during installation. Exact footprint and anchoring instructions should be obtained from the supplier's installation manual.
Regularly inspect and lubricate bearings, gearbox and moving parts, check seals and hydraulic/pneumatic lines (if applicable), ensure fasteners are tight, and follow the manufacturer's service schedule for motor and pump maintenance. Keep records of maintenance and servicing.
Use appropriate PPE, ensure operators are trained on machine use and emergency procedures, confirm emergency stop and guarding are functional, and follow lockout/tagout procedures before maintenance. Adhere to local safety regulations and the supplier's safety instructions.
Common applications include furniture manufacturing and assembly (chair and sofa legs), custom furniture projects requiring precise tube ends, automated production lines, and general metalworking/fabrication tasks involving tube end sizing.
Yes—many suppliers offer customization or tooling options to fit specific tube sizes, materials or integration needs. Contact the vendor or sales representative to discuss special tooling, control options or custom configurations.
Because the unit is heavy (~1000 kg) it is typically crated and shipped by freight; handling requires forklifts/cranes. After-sales support, warranty terms and spare parts availability vary by supplier—please contact the vendor for warranty coverage, service contracts and shipping/installation assistance.
