LHS240-24 Wire Drawing Machine for Cable Factories 2026

Introducing Changzhou Dingtian Electrical Machinery Co., Ltd. and the LHS240-24

Changzhou Dingtian Electrical Machinery Co., Ltd., operating under the brand Dingtian, is headquartered at No. 10, Dangnan Industrial Park, Tianning District, Changzhou City, Jiangsu Province, China. The company positions itself as a manufacturer of wire drawing machines for the electronic wire and wire cable industry, supplying precision ultra-fine and fine wire drawing equipment with servo, slip-type, tension-rod-free, and in-line continuous annealing configurations. Among its 14-product lineup, the LHS240-24 Tension-Rod-Free Fine Wire Drawing Machine stands out as a high-capacity solution built for factories that need dependable, large-volume output of fine copper wire.

Why Wire and Cable Factories Look for This Type of Equipment

Wire and cable manufacturers commonly face mechanical tension fluctuation that causes wire breakage and diameter variation, alongside high equipment procurement cost compared with international suppliers and heavy reliance on operator skill. For factories running thicker fine wire at scale, additional pain points include severe tension fluctuation in thicker wires, cooling limitations during prolonged high-speed operation, spool changeover downtime, and the need for high-volume output. The LHS240-24 was engineered specifically to address these operational realities.

Product Positioning and Core Differentiated Value

The LHS240-24 is described as a high-capacity, tension-rod-free fine wire drawing machine with a maximum line speed up to 2,500 m/min. Its differentiated value centers on four pillars:

• Fine wire processing: The machine supports a minimum finished wire diameter of 0.10 mm, enabling fine wire drawing for demanding applications.
• Production efficiency: With a maximum line speed of up to 2,500 m/min, the machine is reported to produce approximately 2,880 km of 0.2 mm finished copper wire per day at 2,000 m/min, rising to approximately 3,600 km per day at 2,500 m/min — a 25% increase in production capacity under the same process and wire specification.
• Tension stability: An enhanced dual-inverter closed-loop slip control suppresses tension impact during startup, shutdown, and speed adjustment, which helps avoid uneven wire thickness — a direct response to the tension fluctuation issues common in thicker-wire drawing.
• Expandability: The machine can be easily connected with pay-off machines, annealing machines, and take-up units to form an automatic production line, supporting line-level integration for factories planning to scale or automate further.

Key Engineering Features

Several design choices reinforce the LHS240-24’s suitability for continuous, heavy-duty factory operation:

• Reinforced frame: A thickened and reinforced machine frame with fatigue resistance is built to support round-the-clock uninterrupted production in large cable factories.
• Upgraded cooling and lubrication: Increased spray flow and an enlarged circulation oil tank maintain stable lubricant temperature, helping prevent wire oxidation and blackening during long production runs.
• Large-capacity spools: The machine supports large-capacity single spools, which reduces downtime associated with spool changeover and improves overall line efficiency.

Technical Specifications

For factories evaluating fit against existing production requirements, the LHS240-24’s technical profile includes:

• Inlet wire blank: 0.55 mm to 1.2 mm
• Outlet finished product: 0.10 mm to 0.40 mm
• Maximum line speed: 2,500 m/min
• Maximum number of molds: 24
• Cone pulley: Φ240×11 sections, 4 sets
• Constant speed pulley: Φ240, 1 set
• Main motor: 15 kW
• Take-up motor: 5.5 kW
• Whole machine weight: 2.13 T

The equipment is delivered as industrial equipment supply, with take-up reel dimensions customizable to customer specifications. Suggested industry adaptation includes large enameled wire factories, power auxiliary material manufacturers, and wire harness producers — segments that typically demand consistent high-volume fine wire output.

Market Validation and Customer Feedback

Dingtian’s broader customer base offers relevant context on how its wire drawing equipment performs under sustained factory conditions. In one long-term customer relationship, Dingtian supplied wire drawing machines built with internationally renowned brand components and robust construction, paired with customized support covering equipment configuration, process parameters, and after-sales service. The reported result: the customer’s machine required no major overhaul after 8 years of operation. The customer testimonial cited reliable equipment quality, fast after-sales support, and continuous technical support throughout the cooperation.

In another documented case involving customized micro wire drawing for export products, Dingtian optimized equipment configuration and process parameters based on the customer’s wire processing requirements. The quantified results included a finished wire dimensional tolerance of ±0.0006 mm, a surface roughness of Ra ≤ 0.015 μm, passing inspection on the first attempt, an export product qualification rate of 99.8%, and an overseas order volume increase of 60%. While this particular case referenced micro wire drawing rather than the LHS240-24 specifically, it illustrates the company’s broader pattern of customization-driven quality outcomes that factories evaluating any Dingtian model, including the LHS240-24, can reasonably expect from the same engineering and service approach.

Certifications Supporting Buyer Confidence

Dingtian holds a GB/T 19001-2016 idt ISO 9001:2015 quality management system certification (certificate no. 75424Q0525R0S), a GB/T 24001-2016 idt ISO 14001:2015 environmental management system certification, and a GB/T 45001-2020 idt ISO 45001:2018 occupational health and safety management system certification. The company was also recognized as a Provincial Specialized and Innovative Small and Medium-Sized Enterprise by the Jiangsu Provincial Department of Industry and Information Technology, effective from April 2024 to April 2027. These certifications provide third-party-verified structure around the company’s manufacturing and quality processes.

Service and Delivery Model

Beyond the hardware itself, Dingtian’s service scope covers equipment customization, process commissioning, production support, and after-sales support, including equipment appearance customization according to customer branding requirements. For factories investing in equipment like the LHS240-24, this means access to customized equipment configuration and process parameter optimization, along with wire trial verification at the Dingtian facility before or after purchase.

Conclusion

For wire and cable factories that need to move beyond the limitations of conventional tension-rod drawing equipment, the LHS240-24 offers a combination of high line speed, reinforced build quality, improved cooling and lubrication, and large-capacity spool support designed for continuous, high-volume fine wire production. Backed by Dingtian’s certified quality systems and a service model built around customization and after-sales support, the LHS240-24 represents a practical option for large enameled wire factories, power auxiliary material manufacturers, and wire harness producers seeking dependable, scalable fine wire drawing capacity.
