This integrated cable extrusion equipment is designed for insulation processing of XLPE and PE materials, combining a single-screw extruder, temperature-controlled heating system, and multi-section water cooling tank. It supports continuous production of insulated cables, addressing uneven insulation thickness and inconsistent cooling effects in conventional extrusion setups. The equipment complies with IEC, GB, and ANSI cable insulation standards, and is suitable for power cable, communication cable, and automotive wire manufacturing.
The machine is equipped with a single screw with a 30:1 length-to-diameter ratio, made of 38CrMoAl alloy steel with nitriding treatment. The screw design supports uniform plasticization and melting of XLPE and PE materials. The screw surface hardness reaches HRC 60-65, with a service life of over 5 years under standard operating conditions. Two screw diameter options, 65mm and 75mm, are available to match different production output requirements.
The temperature control system is based on PLC technology, monitoring 5 independent heating zones: feed zone, compression zone, metering zone, die head, and adapter. Temperature control accuracy reaches ±1℃, preventing material degradation caused by overheating or insufficient plasticization due to low temperatures. The system stores temperature parameter presets for common materials to reduce setup time during material changes.
The integrated cooling system includes a 3000mm total length water tank made of stainless steel, divided into 3 independent sections with individual temperature control adjustable between 5℃ and 40℃. The first section adopts spray cooling, while the second and third sections use immersion cooling. This combination supports rapid and uniform cooling of insulated cables, reducing internal stress in the insulation layer. A water circulation filtration system is included to maintain water quality.
The water tank is equipped with cable guide devices and tension control rollers to prevent cable deviation during the cooling process. This structure ensures consistent insulation diameter along the cable length, with insulation thickness tolerance controlled within ±0.05mm. An optional laser thickness gauge can be added for real-time thickness monitoring and automatic speed adjustment.

This extruder is used in power cable production lines for manufacturing 1kV-35kV XLPE-insulated power cables for distribution networks. It also applies to communication cable production, processing PE-insulated Cat5e, Cat6, and coaxial cables. In the automotive and marine wire sector, it produces PE-insulated wiring harnesses and marine cables that meet corresponding industry standards. It is suitable for both continuous mass production and small-batch custom cable orders.
The machine can process batches as small as 50kg of XLPE granules, making it suitable for both large-scale production runs and small-batch custom orders.
A dedicated cleaning agent is used for material changeover, with a standard cleaning process taking 20-25 minutes. The split-type barrel design allows access to the screw for thorough cleaning when needed.
The water filter should be replaced every 2 weeks under standard operating conditions to prevent impurities from adhering to the cable surface and affecting insulation surface quality.
Yes, the machine can be equipped with an optional laser thickness gauge that monitors insulation thickness in real time and adjusts extruder speed automatically to maintain thickness tolerance within ±0.05mm.
