An insulation extrusion line is a specialized production system designed to coat or jacketing conductors, cables, or other elongated products with a protective insulating layer. The 60/35 insulation extrusion line is typically used for medium-scale cable manufacturing, offering a balanced combination of output stability, processing precision, and operational flexibility. It is suitable for producing insulated wires and cables used in electrical, industrial, and communication applications.This type of extrusion line usually consists of several main components, including a pay-off unit, preheating device, extrusion machine, crosshead die, cooling system, capstan, accumulator, spark tester, meter counter, and take-up unit. Each section works together to ensure that the insulating material is applied evenly and consistently onto the conductor. The 60/35 specification generally refers to the screw and barrel size of the extruder, which influences plasticizing capacity, melting efficiency, and production output. A properly designed screw structure helps to achieve uniform material mixing, stable pressure, and smooth extrusion performance.The line is commonly used with insulating materials such as PVC, PE, XLPE, and other thermoplastic compounds. These materials are selected according to the required electrical performance, temperature resistance, flexibility, and mechanical durability of the final product. During production, the conductor is first unwound from the pay-off, then passed through a preheating section to improve adhesion and remove moisture. After that, the material is melted and extruded through the crosshead die, where it forms a continuous insulation layer around the conductor. The product then enters the cooling tank to solidify the insulation and maintain dimensional accuracy.One of the key advantages of a 60/35 insulation extrusion line is its ability to maintain stable line speed while producing high-quality insulated products. Advanced temperature control and automatic tension regulation help reduce defects such as uneven thickness, surface roughness, bubbles, or eccentricity. The line can also be equipped with digital controls and monitoring systems, allowing operators to adjust parameters efficiently and improve production consistency.In addition, the equipment is designed for energy efficiency and easy maintenance. Its modular structure simplifies installation, operation, and future upgrades. With proper configuration, the line can support a wide range of cable sizes and insulation thicknesses, making it a versatile solution for many manufacturing needs. The combination of reliable performance, precise control, and broad material compatibility makes the 60/35 insulation extrusion line an important machine in modern wire and cable production.
