The global cable manufacturing industry is rapidly evolving toward higher efficiency, intelligent automation, energy-saving production, and wider material compatibility. As modern cable applications continue expanding in construction, power transmission, renewable energy, rail transit, and industrial automation, cable manufacturers are under increasing pressure to improve product quality while reducing production costs and downtime.

To meet these growing industry demands, Handing has officially launched the new-generation EXT45-26DS Extruder, a high-performance cable extrusion machine specially designed for mid-to-high-end cable production.

Combining advanced European extrusion technology with domestic manufacturing innovation, the EXT45-26DS double-drive extruder delivers outstanding plasticizing performance, stable intelligent operation, enhanced torque output, and exceptional compatibility with various cable materials.

• Building wire extrusion

• Power cable production

• LSZH cable manufacturing

• HFFR cable extrusion

• Photovoltaic cable production

• Control cable sheathing

• Special cable processing

For cable manufacturers seeking higher efficiency, better product consistency, lower maintenance costs, and smarter factory integration, the EXT45-26DS provides a highly competitive extrusion solution for modern cable production lines.

Why the Cable Extrusion Industry Is Upgrading Rapidly

In recent years, the cable industry has experienced significant technological transformation.

Several major trends are driving equipment upgrades worldwide:

• Growing demand for flame-retardant cables

• Expansion of renewable energy cable applications

• Increasing use of LSZH materials

• Higher automation requirements

• Rising labor costs

• Stricter environmental regulations

• Smart factory development

• Demand for stable high-speed extrusion

Traditional extrusion equipment often struggles to meet modern production requirements, especially when processing difficult materials such as LSZH compounds, HFFR materials, EPDM, and high-filler flame-retardant compounds.

EXT45-26DS: Model Definition and Accurate Product Positioning

Every code in the EXT45-26DS model name represents key technical characteristics and core performance advantages.

EXT — Handing Extruder Series

“EXT” stands for Extruder and represents Handing’s professional extrusion equipment product line.

• High-speed cable extrusion

• Intelligent automation

• Stable plasticization

• Energy-saving operation

• Multi-material compatibility

45 — 45mm Screw Diameter

The machine adopts a 45mm screw diameter configuration, which is highly suitable for medium and small cable extrusion applications.

This size provides an excellent balance between production efficiency, plasticizing performance, material stability, and flexible application range.

26 — Length-to-Diameter Ratio of 26:1

The 26:1 L/D ratio is carefully optimized to achieve excellent melting performance, stable plasticization, higher extrusion output, better material dispersion, and improved cable surface quality.

DS — Double Drive Reinforced System

One of the biggest upgrades of the EXT45-26DS is the reinforced Double Drive (DS) system.

Compared with traditional single-drive extrusion systems, the DS configuration delivers:

• Higher torque output

• Better operational stability

• Stronger material processing capability

• Improved extrusion consistency

This design is especially suitable for high-filler and difficult-to-process materials widely used in modern flame-retardant cable manufacturing.

Outstanding Core Performance of the EXT45-26DS Extruder

1. High-Efficiency Extrusion Performance

The machine is equipped with a high-performance main motor and reinforced double-drive transmission system.

• Torque output increased by more than 30%

• Stable high-speed extrusion

• Improved material conveying capability

• Reduced production fluctuation

• Higher operational reliability

The optimized screw design supports processing of various materials including PVC, PE, HFFR, LSZH, LSHF, and EPDM.

Under PVC and PE working conditions, stable extrusion output reaches 50–120kg/h, while the maximum line speed reaches up to 200m/min.

Compared with conventional extrusion equipment of similar specifications, production efficiency improves by approximately 15%–20%.

2. Precise Temperature Control for Stable Plasticization

Plasticization stability is one of the most important factors in cable extrusion quality.

The EXT45-26DS adopts:

• 5–6 independent temperature control zones

• Heating power of 18–24kW

• Temperature control precision of ±1°C

The system monitors temperature across the barrel, feeding section, crosshead, and gearbox while pressure sensors continuously monitor melt pressure conditions.

• Prevents uneven plasticization

• Reduces temperature fluctuation

• Improves insulation density

• Enhances sheath smoothness

• Maintains stable outer diameter

The machine supports cable production ranging from Φ5mm to Φ40mm.

3. Reinforced Double Drive for Difficult Materials

One of the major technical highlights of the EXT45-26DS is its reinforced DS double-drive structure.

Modern cable production increasingly relies on LSZH compounds, HFFR materials, and high-filler flame-retardant compounds, which are difficult to process using ordinary extrusion machines.

Traditional equipment often experiences:

• Insufficient torque

• Frequent stalling

• Poor material dispersion

• Unstable extrusion

• High wear rates

The EXT45-26DS effectively solves these issues.

Advanced Wear Resistance

The nitrided screw and barrel provide:

• Excellent wear resistance

• Strong corrosion resistance

• Longer service life

• Reduced maintenance frequency

Compared with ordinary extrusion components, service life improves by approximately 40%.

4. Intelligent PLC Control and Smart Operation

Modern cable factories increasingly demand intelligent automation systems.

The EXT45-26DS is equipped with:

• PLC intelligent control system

• Touch-screen interface

• One-key startup

• Automatic fault diagnosis

• Parameter preset functions

These intelligent features simplify operation while reducing human error.

MES Integration and Remote Monitoring

The machine also supports:

• MES data acquisition

• Ethernet remote monitoring

• Real-time production data upload

• Remote commissioning

• Remote maintenance

This makes the equipment highly suitable for smart factory environments and Industry 4.0 production systems.

Energy-Saving Production

The smart power monitoring system helps manufacturers:

• Monitor energy consumption accurately

• Optimize power usage

• Reduce operating costs

• Support green manufacturing goals
