Proper maintenance of hanger forming machines is essential to ensure smooth production, consistent quality, and a long equipment lifespan. These machines are critical in wire processing industries, forming precise and uniform clothes hangers made of steel, aluminum, or other materials. Regular care minimizes downtime and reduces repair costs, making it an important part of factory management.

Routine Cleaning and Inspection

The first step in maintaining hanger forming machines is routine cleaning. Dust, metal shavings, and oil residues can accumulate around the feeding rollers, bending heads, and cutting blades, affecting precision and increasing wear. Operators should wipe down the machine surface daily using lint-free cloths and non-corrosive cleaning agents.
Inspect the wire guide and straightening system for buildup, as any obstruction may cause deformation or inconsistent wire feeding. Weekly inspection should include checking all bolts and screws to ensure they remain tight, preventing mechanical vibration during continuous operation.

Lubrication is also part of regular inspection. Bearings, guide rails, and gearboxes should be lubricated with the manufacturer-recommended oil to reduce friction. Neglecting lubrication can lead to overheating and shorten the lifespan of the forming components.

Electrical and Control System Maintenance

The control system plays a vital role in machine precision and safety. Operators should inspect the control cabinet for dust and humidity, keeping it clean and dry at all times. Electrical terminals and connections must be checked monthly to prevent loosening caused by vibration.

The sensors that measure wire length and bending angles require calibration to maintain accuracy. Faulty sensors or damaged cables can result in incorrect forming cycles or unintentional stops. It is advisable to keep spare sensors and fuses ready for quick replacement.
If the machine features a programmable logic controller (PLC), back up the operating parameters regularly to avoid data loss during power fluctuations. Additionally, ensure the cooling fans and ventilation system of the control box are functioning properly to prevent overheating.

Mechanical Components and Tooling Care

Mechanical wear is unavoidable during continuous production, but proper care can minimize it. The feeding rollers, bending heads, and cutting blades are the most stressed parts and should be inspected every 100 operating hours. Dull or chipped blades should be replaced immediately to prevent poor cuts or wire burrs.
Straightening rollers should also be adjusted periodically to keep the wire alignment consistent. If the machine uses different wire diameters, recalibration of the feeding tension and bending pressure is necessary to avoid overloading the drive motors.

It is also important to align and balance the mechanical components after each tool replacement. Unbalanced tooling may cause uneven hanger shapes or wire twisting. Record every replacement and adjustment in a maintenance log to track performance and prevent repetitive issues.

Safety and Preventive Maintenance

Safety is integral to machine maintenance. Before any cleaning or servicing, disconnect the power supply and release the air pressure if the system uses pneumatic components. Only qualified technicians should handle internal electrical components or replace critical mechanical parts.

Preventive maintenance schedules should be followed strictly. Regularly test the emergency stop buttons, limit switches, and overload protection systems to ensure they are functioning correctly. Proper grounding of the machine body helps prevent electrical hazards during operation.
Operators should receive training to recognize early signs of malfunction such as abnormal vibration, excessive noise, or inconsistent hanger shape. Addressing these signs promptly prevents more serious mechanical failures.

Professional Service and Support

Although in-house maintenance covers most daily needs, professional servicing from the manufacturer ensures long-term reliability. Periodic inspection by experts allows detection of hidden issues such as internal bearing wear or misalignment of servo systems.

For high-performance hanger forming machines, choosing a reliable manufacturer with strong after-sales support is essential. WECAN provides advanced hanger forming solutions with comprehensive maintenance guidance and technical support.
