Redefining Cable Manufacturing Through Precision and Automation

In the intricate world of wire and cable production, every strand matters. The demand for faster, more efficient, and precisely controlled manufacturing has pushed machinery design to new frontiers. Among the most transformative innovations stands the cable stranding machine — a cornerstone of modern cable production that determines not only product integrity but also production efficiency and long-term performance.

One company has been leading this transformation from the heart of China’s industrial hub: Dongguan Dongxin (DOSING) Automation Technology Co., Ltd., a national high-tech enterprise founded in 2009. With more than 15 years of relentless innovation and the visionary leadership of founder Mr. Lin Huazhong, DOSING has redefined what’s possible in the automation of wire and cable manufacturing.

What Is a Cable Stranding Machine?

At its core, a cable stranding machine is designed to twist multiple single wires or cores together to form a compact, uniform cable. This process ensures flexibility, mechanical strength, and electrical consistency — essential for data transmission, power distribution, and signal integrity.

In traditional setups, stranding operations were often limited by mechanical constraints and manual adjustments. Operators struggled with uneven tension, vibration, and speed fluctuations that directly affected product quality. Today, the integration of advanced automation and control systems has revolutionized the process.

How the Stranding Process Works: Step-by-Step

A cable stranding machine operates through a precisely synchronized mechanical and electrical sequence. Understanding its inner workings reveals why DOSING’s systems have become synonymous with reliability and speed.

1. Wire Pay-off Unit:
   Individual wires are released from the pay-off reels with constant tension control. DOSING’s shaftless pay-off system minimizes mechanical friction and allows quick reel changes, reducing downtime.

2. Stranding Section:
   The core mechanism of the machine, where wires are twisted together using a rotating cage or a single-twist/ double-twist system. This step determines strand pitch, compactness, and overall structure. DOSING’s advanced single twist and double twist machines employ servo-driven synchronization, ensuring stable rotation even at high speeds.

3. Take-up System:
   Once twisted, the stranded cable is neatly wound onto reels or spools. DOSING’s automatic tension feedback ensures that the cable maintains uniform density and alignment during winding.

4. Control & Monitoring:
   Modern cable stranding machines use PLC (Programmable Logic Controller) systems integrated with HMI (Human-Machine Interface) screens for real-time monitoring. Operators can adjust parameters like stranding pitch, tension, and rotational speed digitally — achieving both precision and repeatability.

Innovation Spotlight: PLC Control Integration by DOSING

When Mr. Lin Huazhong first pioneered the integration of PLC control panels into cantilever single-strand machines, it marked a turning point for the industry. Before this breakthrough, cable manufacturers faced consistent speed bottlenecks and inefficiencies in manual operations.

By embedding PLC logic with servo motor coordination, DOSING achieved:

• Speed improvement of over 40%,

• Consistent stranding tension, and

• Fully synchronized multi-axis control that reduced mechanical stress on both wire and machine.

This innovation not only optimized performance but also established a new benchmark in cable machinery automation across Asia’s competitive market.

Types of Cable Stranding Machines

The term “cable stranding machine” encompasses several specialized systems designed for different cable types and applications. DOSING offers a comprehensive range tailored to diverse production requirements:

1. Single Twist Machine – Ideal for small conductor stranding and data cables, ensuring smooth twist performance.

2. Double Twist Machine – Delivers high-speed stranding with reduced lay length, suitable for automotive and communication cables.

3. Pair Twist Machine with Back Twist System – Provides precision back-twisting control for LAN and CAT cables, maintaining consistent impedance.

4. Bunching Machine – Combines multiple fine wires for flexible conductors used in electronic cables.

5. Planetary Strander – Used for larger power cables and control cables that require high torsional stability.

Each variant of the cable stranding machine plays a vital role in maintaining the structural integrity and electrical performance of cables used in modern infrastructure — from electric vehicles to 5G networks.

Why Stranding Quality Matters

In high-performance industries, the smallest inconsistency in cable structure can lead to significant failures. For instance:

• Uneven strand lay can cause impedance mismatch in data cables, leading to signal loss.

• Poor tension control results in cable deformation during insulation or sheathing.

• Inconsistent speed can cause micro-gaps between wires, reducing conductivity.

DOSING’s advanced stranding solutions are designed to eliminate these issues through precision automation, intelligent sensors, and adaptive feedback systems — ensuring every strand aligns perfectly.

Inside DOSING’s Engineering Philosophy

DOSING’s philosophy revolves around one core principle: automation should serve precision, not just speed. The company’s R&D division integrates mechanical design, electrical engineering, and data-driven control systems to achieve optimal performance.

Their multidisciplinary team specializes in:

• Custom mechanical design tailored for different conductor materials and diameters,

• High-speed servo synchronization that minimizes mechanical vibration,

• Dynamic tension balancing, and

• Modular upgrades for future production scalability.

This holistic engineering approach is what has made DOSING the go-to supplier for many global wire and cable manufacturers seeking reliable automation partners.

Full-Cycle Support: From Design to After-Sales Service

Unlike traditional equipment vendors, Dongguan Dongxin (DOSING) provides a one-stop solution — from conceptual design to after-sales technical support. Each project begins with a detailed production analysis to ensure that the selected cable stranding machine matches the specific product mix, speed requirement, and factory layout.

After installation, DOSING’s engineers conduct:

• Operator training sessions,

• On-site calibration, and

This full-lifecycle service model helps manufacturers reduce setup time, optimize energy consumption, and maintain consistent output quality over years of operation.

Automation Synergy: Stranding Meets Extrusion and Taping

A true advantage of DOSING’s system lies in its integration capability. The company’s portfolio extends far beyond stranding, including:

• Extruder Production Lines (Core wire insulation, PVC sheathed, physical/chemical foaming types),

• Automatic Coiling and Taping Machines,

• Wire Pay-off and Cutting Systems, and

• Auxiliary Equipment Series.

When these systems work in harmony, the result is a fully automated, data-connected cable production line that enhances overall efficiency by up to 30–50%, while ensuring quality consistency from start to finish.

Their energy-efficient drive systems, low-noise operation, and intelligent fault diagnostics help manufacturers lower carbon footprints and maintenance costs.

Moreover, the company’s adoption of Industry 4.0 principles — including real-time data monitoring, predictive maintenance algorithms, and networked PLC systems — positions the cable stranding machine as not just a production tool but a data-driven intelligence unit within the smart factory ecosystem.

Common Challenges in Cable Stranding — and How to Solve Them

Even with advanced technology, operators still encounter common stranding issues:
