LHS240 Drawing Machine Factory Delivers High-Speed Fine Wire

Understanding the LHS240 Drawing Machinery Factory Advantage

For wire and cable manufacturers evaluating fine wire drawing equipment, the search for a reliable "LHS240 drawing machinery factory" often begins with a straightforward set of concerns: tension stability, breakage rates, output capacity, and total cost of ownership relative to international brands. Changzhou Dingtian Electrical Machinery Co., Ltd., operating under the brand name Dingtian from its headquarters at No. 10, Dangnan Industrial Park, Tianning District, Changzhou City, Jiangsu Province, China, manufactures the LHS240-24 Tension-Rod-Free Fine Wire Drawing Machine as part of a broader lineup addressing exactly these pain points in the electronic wire and wire cable industry.

Why Tension-Rod-Free Design Matters for Fine Wire Production

Conventional wire drawing equipment relying on mechanical tension rods is prone to tension fluctuation, which in turn causes wire breakage and diameter variation — two of the most persistent challenges cited across the wire and cable manufacturing sector. Dingtian’s product architecture addresses this directly through tension-rod-free and closed-loop control designs, which reduce wire breakage and improve diameter consistency. The LHS240-24 specifically applies this principle at a larger production scale than Dingtian’s smaller slip-type models, making it suited for manufacturers who need both fine wire precision and high-volume throughput.

LHS240-24 Technical Profile

The LHS240-24 Tension-Rod-Free Fine Wire Drawing Machine is positioned for high-capacity fine wire drawing with a maximum line speed up to 2,500 m/min — the highest line speed figure among Dingtian’s disclosed product specifications. Its core technical parameters include:

• Inlet wire blank: 0.55 mm to 1.2 mm
• Outlet finished product: 0.10 mm to 0.40 mm
• 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

For 0.2 mm finished copper wire, the machine is capable of a daily output of approximately 2,880 km at 2,000 m/min and approximately 3,600 km at 2,500 m/min, representing a 25% increase in production capacity under the same process and wire specification when operated at its higher speed setting. This distinction is meaningful for manufacturers comparing throughput scenarios rather than relying on a single speed figure.

Addressing the Core Pain Points of Thicker Fine Wire Production

Manufacturers working with thicker wire ranges typically face more severe tension fluctuation, cooling demands during prolonged high-speed operation, spool changeover downtime, and pressure to sustain high-volume output. The LHS240-24 responds to each of these through specific engineering choices rather than generic claims:

Tension stability is achieved through an enhanced dual-inverter closed-loop slip control system that suppresses tension impact during startup, shutdown, and speed adjustment, which helps avoid uneven wire thickness — a direct consequence of unmanaged tension swings during transitional operating states.

Cooling and lubrication have been upgraded with increased spray flow and an enlarged circulation oil tank, maintaining stable lubricant temperature and preventing wire oxidation and blackening, both of which are common surface-quality defects in continuous high-speed drawing.

Spool capacity is addressed through support for large-capacity single spools, which reduces the frequency of downtime associated with spool changeover and improves overall line operational efficiency.

Structural durability comes from a thickened and reinforced machine frame with fatigue resistance, intended to support round-the-clock uninterrupted production in large cable factories rather than intermittent or lighter-duty use.

Line-Level Integration Capability

Beyond standalone operation, the LHS240-24 is designed to be easily connected with pay-off machines, annealing machines, and take-up units to form an automatic production line. This expandability matters for manufacturers planning to scale from single-machine operation toward integrated, multi-stage production without needing to replace core drawing equipment as their process requirements grow.

Industry Fit

The LHS240-24 is positioned for large enameled wire factories, power auxiliary material manufacturers, and wire harness producers — customer segments characterized by continuous, high-volume operational demands rather than small-batch or highly specialized fine wire work. This differs from Dingtian’s full-servo ultra-micro models such as the QSF45-10, which target precious metal and semiconductor packaging applications requiring finished wire diameters as small as 0.0085 mm. The LHS240-24 instead sits within Dingtian’s broader tension-rod-free product family alongside the LHS220-24, addressing the 0.10 mm to 0.40 mm finished wire range with an emphasis on volume and reliability.

Cost Positioning Relative to International Brands

Across Dingtian’s product line, pricing is consistently reported as lower than international brands, with select ultra-micro models priced at around one-tenth of international equivalents. While the LHS240-24 specification sheet does not carry a stated comparative discount figure, it is manufactured under the same value proposition that governs Dingtian’s broader catalog: enabling wire and cable manufacturers to achieve tighter diameter tolerance, fewer wire breaks, and lower equipment acquisition cost than international alternatives.

Certification and Quality Assurance Framework

Purchasing decisions for capital equipment of this scale typically involve verification of the manufacturer’s quality systems. Changzhou Dingtian Electrical Machinery Co., Ltd. holds Quality Management System Certification under GB/T 19001-2016 idt ISO 9001:2015 (certificate no. 75424Q0525R0S, initial date November 22, 2024, valid until November 21, 2027), Environmental Management System Certification under GB/T 24001-2016 idt ISO 14001:2015 (certificate no. 75424E0248R0S, valid until September 27, 2027), and Occupational Health and Safety Management System Certification under GB/T 45001-2020 idt ISO 45001:2018 (certificate no. 75424S0219R0S, valid until September 27, 2027). 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 April 2024 to April 2027.

Real-World Operational Evidence

One customer case documented by Dingtian describes a machine that required no major overhaul after 8 years of operation, attributed to internationally renowned brand components and robust construction combined with customized support covering equipment configuration, process parameters, and after-sales service. While this case does not specifically reference the LHS240-24 model, it reflects the durability standards applied across Dingtian’s tension-rod-free product family, which shares core design principles including closed-loop slip control and reinforced structural components.

Delivery and After-Sales Model

Dingtian supplies the LHS240-24 with customizable take-up reel dimensions and supports on-site industrial equipment installation. After-sales provisions include technical support and customized after-sales service, consistent with the company’s stated service scope of equipment customization, process commissioning, production support, and after-sales support.
