Metal wire PVC wire is widely used in the electrical field due to its outstanding easy processing characteristics. From production and manufacturing to installation and use, it significantly reduces the difficulty of processing and improves efficiency by virtue of its material characteristics and process adaptation advantages, providing strong support for the development of the industry.
Simple pretreatment of raw materials reduces the production threshold. PVC (polyvinyl chloride) as an insulation and protective layer material has good plasticity and thermal stability, and does not require complicated treatment before production. After mixing PVC raw material particles with additives (such as plasticizers and stabilizers) in proportion, it can be directly put into the extruder for production. Compared with other polymer insulation materials, PVC does not require pretreatment processes such as high-temperature drying and special purification, which reduces production preparation time and energy consumption. Metal wire is used as a conductor, mostly conventional metals such as copper or aluminum. The required specifications can be achieved through simple wire drawing and annealing processes, and it has strong compatibility with PVC materials. It can achieve tight coating without additional surface treatment, which reduces the technical threshold and cost of raw material processing.
Diversified molding processes improve production efficiency. Extrusion molding is the core process of metal wire pvc wire production. PVC has good fluidity in the molten state of 160℃ - 190℃, and can be quickly extruded through the mold to wrap the metal wire. The production equipment is simple to operate. By adjusting the temperature of the extruder, the screw speed and the mold size, the production of wires of different specifications can be quickly switched. The production speed can reach 50-100 meters per minute, which is much higher than some special insulated wires. In addition, pvc wire is also suitable for injection molding. When making connectors or terminal joints, PVC and metal wire can be injected as one, without the need for complex assembly processes, further shortening the production cycle and meeting the needs of large-scale industrial production.
Flexible cutting and connection simplify the installation process. Metal wire pvc wire is flexible and can be easily cut to the required length using ordinary scissors or wire cutters without the need for professional cutting equipment. During the electrical wiring process, construction personnel can adjust the wire length on site according to actual installation needs to avoid waste. In terms of connection, the metal wire of pvc wire can be connected to terminals and electrical components by crimping, welding and other methods. When crimping, the PVC insulation layer does not need to be stripped over a large area. Only a small amount of metal wire needs to be exposed to complete the connection. The operation is simple and not easy to damage the conductor. When welding, the temperature resistance of the PVC material can withstand short-term high temperatures, and there is no need to worry about the melting of the insulation layer affecting the connection effect, which greatly simplifies the installation steps.
Good bending performance adapts to complex wiring environments. Metal wire pvc wire has excellent flexibility, and the minimum bending radius is usually 3-5 times the wire diameter, which can be easily wired in small spaces or complex structures. In building electrical installation, it can be laid along irregular paths such as corners and pipe gaps without additional bending tools or special treatment. When wiring inside electronic equipment, it can be bent at will according to the layout of the circuit board, closely fitting the equipment structure, saving space and facilitating arrangement and fixing. This good bending performance makes the installation process more flexible and efficient, especially for precision equipment with high space utilization requirements.
Surface treatment and labeling are convenient to enhance recognizability. PVC materials are easy to surface treat, and a variety of colors can be customized by adding masterbatch during the production process to distinguish lines with different functions (such as live wire, neutral wire, and ground wire). In addition, the model, specification, rated voltage and other information can be printed directly on the surface of the PVC insulation layer through online printing technology without additional labeling. During the installation process, clear color identification and text information facilitate construction personnel to quickly identify and connect, reduce errors caused by line confusion, and also provide convenience for later maintenance and repair, improving the standardization and reliability of the entire installation project.
Secondary processing has strong adaptability to meet personalized needs. Metal wire pvc wire supports a variety of secondary processing methods, such as heat shrink tubing, wrapping tape, and adding protective sleeves. The heat shrink tubing can be quickly shrunk by heating with a hot air gun, tightly wrapped on the surface of the wire, and enhance the waterproof and wear-resistant performance; the wrapping tape can be used for local insulation repair or reinforcement; the addition of a protective sleeve is suitable for protection in outdoor or special environments. These secondary processing operations are simple and do not require professional equipment. Construction personnel can flexibly choose according to actual needs to meet the personalized installation requirements in different scenarios, further expanding the application scope of metal wire pvc wire.
Environmental protection and cost advantages promote large-scale application. PVC materials are widely available, inexpensive, and have low energy consumption during the production process, which reduces the overall cost of metal wire PVC wire. At the same time, the processing waste of PVC wire can be recycled and reused, and remade into PVC raw materials through processes such as crushing and granulation, reducing resource waste. In the installation process, the high efficiency and low error rate brought by easy processing further reduce labor costs and time costs. This environmental protection and cost advantage has enabled it to be widely used in price-sensitive civil and construction fields, promoting the popularization and development of electrical wiring projects.
