In modern wire hanger production, the main hanger making machine serves as the core of the manufacturing process. However, to achieve continuous production, stable performance, and uniform hanger quality, several auxiliary machines are required to work in coordination. These machines handle wire preparation, coating, shaping assistance, and packaging — all of which are essential for a complete production line.

Wire Straightening and Cutting Machine

The first auxiliary equipment in the hanger production process is the wire straightening and cutting machine. It ensures that the steel wire used in hanger manufacturing is straight and accurately cut to the required length before being fed into the main forming unit. A typical automatic straightening and cutting machine can handle wire diameters from 1.6 mm to 3.0 mm, with a cutting precision of ±0.5 mm and a working speed exceeding 25–30 m/min. Using pre-straightened and uniform-length wire reduces mechanical stress on the main hanger machine and ensures consistent hanger shapes, directly improving productivity and reducing scrap.

Wire Payoff Stand or Decoiler

Before straightening, the wire is unwound from large coils using a wire payoff stand or decoiler. This machine holds and feeds the wire smoothly to prevent tangling or tension fluctuations. Automatic decoilers are usually equipped with a motor-driven feeding system and adjustable tension control. They can support coils weighing up to 500 kg and feed wire at synchronized speeds with the main production line. Stable wire feeding minimizes downtime and ensures continuous operation throughout the production cycle.

Hook Threading or Neck Forming Unit

For certain hanger designs — such as threaded-neck or special-shape hangers — an additional neck forming or threading unit is integrated. This auxiliary machine shapes or threads the neck area of the hanger to allow easy rotation of the hook or to meet special hanging requirements. These systems can process up to 40–45 hangers per minute, depending on the model, and maintain tight dimensional tolerances to ensure uniformity across production batches.

PVC or PE Coating Machine

A plastic coating machine is essential when producing PVC-coated or PE-coated hangers. The coating layer protects garments from slipping and provides a decorative appearance. This system usually includes a heating tunnel, dipping unit, and cooling conveyor. The coating thickness can be controlled between 0.2 mm and 0.4 mm, and color variations can be adjusted according to customer requirements. In addition to improving aesthetics, coating enhances corrosion resistance and extends product lifespan, making it a vital part of high-end hanger production lines.

Powder Coating or Painting Line

For metal wire hangers that require painted or powder-coated finishes instead of plastic coating, a powder coating or spray painting line is commonly installed. This setup generally includes pretreatment tanks, electrostatic spray booths, and curing ovens. The coating ensures strong adhesion and even coverage, achieving surface hardness above 2H and salt-spray resistance over 72 hours. An automated conveyor system often connects these stages, allowing a seamless flow of formed hangers from the main machine to the finishing area.

Dryer or Curing Oven

After coating or painting, hangers need proper curing to ensure the finish adheres uniformly. A curing oven or drying chamber provides consistent heating at 160–200 °C depending on the coating material. With conveyor-based systems, the drying process takes 8–10 minutes, and energy-efficient insulation reduces overall operating costs. This step guarantees the hanger surface is smooth, durable, and ready for packaging.

Polishing or Buffing Machine

To achieve a smooth and shiny surface, especially for galvanized or stainless-steel hangers, a polishing machine is used. Automatic buffing heads can rotate at speeds up to 2800 rpm, removing any minor burrs or oxidation marks. This auxiliary process enhances the final presentation quality and prepares hangers for premium retail or export packaging.

Counting and Packing Machine

Once hangers are fully processed, a counting and packing machine automates the final stage. It counts, bundles, and bags the hangers efficiently, reducing manual labor. A high-speed automatic counter can process up to 60–70 hangers per minute, ensuring consistent bundle sizes. Integration with shrink-wrapping or bag-sealing equipment allows ready-to-ship packaging directly from the line, increasing throughput and cleanliness.

Air Compressor and Electrical Cabinet

Supporting utilities are also essential for stable operation. An air compressor supplies pneumatic power to forming tools, cutters, and ejectors in the main hanger machine. Typical models operate between 0.6–0.8 MPa with a flow rate of 0.36 m³/min. Meanwhile, the electrical cabinet provides centralized control for all connected equipment, maintaining synchronization between wire feeding, forming, and coating steps. Proper configuration of these systems ensures safety and reliability during continuous production.

Complete Hanger Production Line Integration

When combined, these auxiliary machines create a fully automated hanger production line. Below is a simplified layout example:

Each component works in coordination to improve production speed, reduce manual labor, and ensure consistent product quality. For factories aiming to expand production capacity or upgrade quality control, investing in the right auxiliary machines alongside the main hanger making machine is essential for efficiency and competitiveness in global markets.
