In the manufacturing process of power cables, communication cables, and data cables, sheathing extrusion is the final production step. It directly affects the appearance quality of the finished cable and fundamentally determines the product's "market appeal." Moreover, the quality of the sheath layer is closely related to the electrical performance of the finished cable. Choosing a reliable sheathing extrusion line is therefore crucial for cable manufacturers.
Industry Demand Drives Continuous Growth in the Cable Extruder Market
According to market research reports, the global cable extruders market is expected to reach approximately USD 5.4 billion in 2025 and grow to USD 8.2 billion by 2032, with a compound annual growth rate (CAGR) of 6.2%. This growth is mainly driven by the telecommunications industry, the renewable energy sector, and ongoing global infrastructure investments. Particularly in the Asia-Pacific region, rapid industrialization, communication network construction, and large-scale renewable energy projects are fueling sustained demand for cable extrusion equipment. Against this backdrop, cable manufacturers urgently need efficient, stable, and material-compatible sheathing extrusion lines to enhance production capacity and product competitiveness.
As a professional manufacturer with years of experience in R&D and production of wire and cable manufacturing equipment, LINT TOP sheathing extrusion line is specifically designed for outer sheath extrusion of insulated cores or stranded cores. This line is suitable for producing sheaths for various types of cables and can extrude multiple sheath materials such as PVC, PE, and LSZH/HFFR. It features uniform extrusion diameter, smooth surface finish, high production speed, high efficiency, precise take-up and pay-off tension control, and easy operation.
The LINT TOP sheathing extrusion line offers optional imported screw and barrel combinations to meet different material processing requirements. Whether for PVC, PE, LSZH, or more challenging materials such as Teflon and Nylon, matching dedicated screw and barrel assemblies can achieve high extrusion output and excellent plasticization. The core component of the line—the extruder—uses an advanced BM high-speed screw. The screw is nitrided for stable output and uniform sheath diameter. The extruder head employs a high-precision adjustable eccentric crosslinking head to achieve very high sheath concentricity.
Diverse Configurations to Cover Different Production Needs
LINT TOP offers multiple models such as LT90, LT120, LT150, and LT200 to suit various production capacities and applications. Taking the larger model LT200 as an example, its applicable outer diameter range is Φ70-180 mm, with a screw diameter of 200 mm, a length-to-diameter ratio (L/D) of 25:1, and a maximum extrusion output of up to 1200 kg/h (PVC). Line speed is adjustable between 30 m/min and 80 m/min depending on the model, and the maximum pulling force can reach up to 3200 kg, meeting the requirements of large-scale continuous production from small-medium to large cables.
The sheathing extrusion line mainly consists of a pay-off stand, an inlet tension accumulator, an inlet tension equalizer, an extruder main unit (including an adjustable head and extrusion tooling), an automatic vacuum loader (with hopper dryer), a stainless steel cooling trough, a wheeled capstan, an outlet tension accumulator, a take-up unit, and an electrical control system. An optional aluminum foil/Mylar tape longitudinal taping device can further expand the line's functionality.
Wide Range of Applications Covering Multiple Cable Types
Power Cables: Power cable sheath extrusion
LAN Cables: Suitable for Cat5, Cat5e, Cat6 LAN cable sheath extrusion
Optical Fiber Cables: Optical fiber cable outer sheath extrusion
With its excellent extrusion coating capability for thermoplastic materials such as PVC, PE, and LSZH, the LINT TOP sheathing extrusion line can be configured and combined according to different material characteristics and individual customer requirements, achieving energy-efficient, high-performance, and intelligent production.
Complete After-Sales Service System
LINT TOP not only provides high-quality equipment but also offers comprehensive installation, commissioning, and technical support services. After equipment delivery, the company dispatches mechanical and electrical engineers to the customer's site for equipment start-up and commissioning. No-load testing and load testing are carried out sequentially to ensure that equipment performance fully meets contract requirements before the customer signs the acceptance report. During the warranty period, LINT TOP continues to provide technical support to ensure long-term stable operation of the production line.
In today's increasingly competitive cable manufacturing industry, choosing an efficient, stable, and compatible sheathing extrusion line is key to enhancing production capacity and product quality. Leveraging years of technical expertise, advanced screw design, and reliable manufacturing processes, LINT TOP provides professional production solutions for cable manufacturers worldwide.
For a detailed quotation, you can provide information such as the cable specification sheet to be produced, production capacity requirements, and applicable standards. LINT TOP will then design the most suitable complete line solution according to specific needs.
