High-Precision Rigid Strander for Efficient Conductor Twisting

The Rigid Strander is a core piece of equipment in modern wire and cable manufacturing, widely used for stranding large-length and large-section aluminum, aluminum alloy, bare copper, and steel core aluminum conductors. It is especially suitable for round and sector-shaped conductors as well as tightly pressed cores without back twisting, where stranding quality directly determines the final cable performance.

Compared with traditional ground-shaft-driven machines, the Rigid Strander adopts an advanced individual motor drive system. Each cage and capstan is powered by a separate motor, resulting in a simpler structure, lower noise, and higher operating stability. Pneumatic tension control and automatic adjustment ensure constant tension regardless of bobbin size, while synchronized loading and unloading improve efficiency. With multiple safety protections and reliable performance, this equipment provides a stable, efficient, and easy-to-maintain solution for high-quality conductor stranding.

LINT TOP Launches China's First Individual Motor Driven 16-Head Wire Drawing Machine, Pushing the Boundaries of Copper Wire Drawing

LINT TOP has successfully manufactured and shipped China's first individual motor driven 16-head wire drawing machine. This multiwire drawing machine adopts innovative 16-wire synchronous drawing technology and a fully independent servo motor drive system, marking a pioneering breakthrough for the domestic industry in specific technological fields of high-end precision wire processing equipment.

This pioneering technology for 16-head wire drawing machines will directly impact a wide range of industries from power transmission to microelectronic components, signaling the entry of the wire and cable manufacturing sector into a new stage of high-efficiency and high-precision production.

1. Technological Pioneer: Defining a New Benchmark for Multi Wire Drawing Machine

In the field of multiwire drawing machine, while the concept of multi-wire synchronous drawing is not new, the breakthrough achieved by LINT TOP lies in the first complete application of the top-tier control technology—"each drawing capstan driven by an independent servo motor"—on a 16-head wire drawing machine in China.

Traditional multiwire drawing machines often employ dual-motor or multi-motor schemes. Achieving fully independent servo drive for the 16-head specification, which balances efficiency and flexibility, is a domestic first. This grants this 16-head wire drawing machine unparalleled process flexibility, with one of its most significant advantages being the ability to achieve an extremely wide range of outlet wire diameters.

Through the touchscreen control system, users can freely input different inlet and target outlet wire diameter parameters. The system then automatically adjusts the speed and tension of each independent servo motor. This allows this 16-head wire drawing machine to easily adapt to a very broad spectrum of wire production requirements across different specifications.

 

2. Design Innovation: A Production Solution Integrating Modularity and Intelligence

This 16-head wire drawing machine adopts a split-type independent drawing cabinet design. Each cabinet can be independently opened and closed for maintenance and mold changes. When adjusting wire diameter specifications, operators can quickly replace specific molds without waiting for the entire machine to cool down, minimizing downtime.

The multiwire drawing machine employs a combined sealing system integrating mechanical seals and frame seals at multiple key points, particularly featuring a double-seal design at the connection between the body and the main shaft. This structure effectively prevents leakage of lubricating coolant and ingress of external contaminants, ensuring stability during high-speed continuous operation.

The LINT TOP R&D team has introduced a fully submerged lubrication and cooling system, immersing the drawing dies and wires completely in a special coolant. Compared to traditional spray cooling methods, this design achieves 360° cooling, instantly carrying away the heat generated during the wire drawing process.

 

3. Intelligent Control: Comprehensive Upgrade of Human-Machine Interaction and Process Monitoring

The operational core of this multiwire drawing machine is a highly integrated touchscreen control system, with an interface intuitively displaying all key process parameters. Users need only input the inlet wire diameter, outlet wire diameter, and the actual parameters of each die, and the system can automatically calculate and optimize the entire drawing process curve.

The control system features real-time process monitoring and intelligent diagnostic functions, continuously tracking dozens of parameters including the status of each motor, drawing tension, and coolant temperature. The system immediately triggers an alarm when any abnormality is detected or when operating conditions deviate from preset ranges.

 

4. Industry Impact: Redefining Standards for High-End Wire Manufacturing

The launch of this first domestic individual motor driven 16-head wire drawing machine by LINT TOP breaks through the technological barriers maintained by domestic and foreign manufacturers in this niche segment of high-end drawing equipment. Particularly in terms of fully independent servo motor drive and multi-head synchronous control, China's equipment manufacturing industry has reached internationally advanced levels.

For wire and cable manufacturers, this machine brings not only a significant boost in production efficiency. Its exceptional stability and consistency make the production of high-end products like ultra-fine wires and special wire types possible, directly driving technological upgrades and added value for downstream wire and cable products.

Its low-noise, low-failure-rate operation, coupled with its high-efficiency and energy-saving design philosophy, makes this equipment fully compliant with the requirements of modern green manufacturing.

 

This first domestic individual motor driven 16-head wire drawing machine, independently developed and produced by LINT TOP, is now on its way to our customer's factory. Next, it will undergo rigorous installation and commissioning in preparation for its final step: entering efficient and precise production operation.

From traditional single-head to multiwire drawing machine, from gear transmission to fully independent servo motor transmission, China's equipment manufacturing industry is redefining the meaning of "precision." This step by LINT TOP delivers not just a piece of equipment, but an entirely new production solution for the wire and cable industry.
