Product Description：

Kewang Machinery has been deeply involved in the field of metal wire processing equipment for decades. Our PVC coating machine integrates advanced plastic extrusion technology, precise temperature control, and a stable traction system. Its working process is as follows:

1. Precision Preheating: The metal substrate is evenly preheated to remove moisture and stress, ensuring that the PVC coating achieves optimal bonding strength with the substrate.

2. High-temperature Extrusion Coating: A specialized screw extrudes the molten PVC material evenly and densely onto the surface of the metal wire, forming a continuous, smooth protective layer.

3. Water Cooling Setting: A precisely designed cooling tank quickly cools and sets the coating, maintaining the predetermined diameter and                                                                                                  roundness.

4. Automatic Winding: Equipped with a frequency-controlled winding device, the wire speed is smooth and adjustable, and the winding is neat,                                                                                         preparing for the next process.

The above line including the following parts:

1.Wire winding:

Enhancing Quality and Efficiency: The frequency control ensures constant tension during the winding process, eliminating inconsistent tension and messy stacking of wire materials, resulting in neat and uniform rolls. This not only makes the finished product more aesthetically pleasing but also allows for smooth and efficient unwinding in the subsequent production processes, reducing interruptions and waste.Saving Labor and Costs: Fully automatic winding eliminates the need for constant supervision, allowing one person to manage the entire production line, significantly reducing labor costs and enhancing production safety.

2.Wire decoiler:

The unwinding frame is intelligently linked with the main machine through a PLC control system, which enables automatic speed matching. The simple and intuitive user interface allows employees to get started after brief training, realizing the automation and intelligence of production. The machine body, made of high-quality steel and featuring a reinforced structural design, has a strong load-bearing capacity and high stability. The robust and durable nature of the equipment ensures stable and reliable performance even under long-term high-load operation.

3.Wire tension parts:

Utilizing high-precision tension sensors and a servo feedback system, real-time fine-tuning is achieved, ensuring that the tension fluctuations of the metal wire during travel are minimal. Our tension system provides a continuous and appropriate level of tension, allowing the PVC material in its molten state to tightly envelop the metal wire, creating a robust “clamping” effect. This not only enhances the electrical insulation and durability of the product but also fundamentally eliminates quality defects caused by insufficient adhesion.

4.Extruder machine:

We utilize imported PID intelligent temperature control modules and a multi-zone independent temperature control system to achieve precise temperature control within ±1°C for each stage of the extruder, from the feed opening to the die head. This ensures that the product has a pure color, smooth surface, and stable performance. Equipped with high-efficiency and energy-saving motors, as well as an optimized insulation system, our thermal energy utilization rate is industry-leading. Compared with ordinary equipment, energy consumption can be reduced by 15% to 20%, enhancing your long-term profit margins.

5.Electric control box :

The electrical control system adopts centralized integrated control, achieving full-line interlinking from unwinding, preheating, extruding to rewinding. Operators only need to make simple settings on the user-friendly touch screen, which reduces the risk of human misoperation and improves the machine startup efficiency. The electrical control system is equipped with comprehensive electrical protection against overload, overvoltage, undervoltage, short circuit, and overtemperature, and features an emergency stop button and key operation permission management. This minimizes potential losses.

6.Cooling parts:

The inner wall of our cooling system is designed to be smooth, and it is equipped with an efficient water circulation and filtration device to maintain the cleanliness of the cooling water. Meanwhile, precise constant temperature control ensures that the PVC surface can form a perfectly smooth, mirror-like appearance during the shaping process, significantly enhancing the product’s added value and market competitiveness. There is no need to worry about incomplete cooling, which greatly improves overall production efficiency and breaks through the capacity ceiling.

7.Wire pulling parts :

We utilize heavy-duty reinforced tracks and a high-torque drive system to provide continuous, powerful, and stable traction. Whether it is smooth steel wire, copper wire, or large-diameter cables, they can be firmly gripped to ensure no slipping at high speeds, meeting your needs for high-efficiency production. The machine body is made of high-strength cast iron or steel plate welding, and the key transmission parts have been specially heat-treated, with extremely high wear resistance.

8.Wire recoiler

Cowan uses a precision traversing mechanism driven by a servo motor, which achieves precise interlinking with the main shaft winding. The traversing pitch can be accurately set, ensuring that the wire is tightly and neatly wound layer by layer onto the bobbin, forming a robust and aesthetically pleasing wire reel. This greatly enhances the product’s professional image and customer satisfaction. Operators can easily set parameters such as the reel specifications, winding length, and tension on the main control touch screen, reducing the reliance on skilled workers.
