Wire and cable producers searching for a reliable LHS240 drawing machinery factory often face a common set of challenges: mechanical tension fluctuation that leads to wire breakage, inconsistent diameter control, high procurement costs when comparing equipment against international suppliers, and equipment that struggles to keep pace with large-volume production demands. Changzhou Dingtian Electrical Machinery Co., Ltd., operating under the brand name Dingtian, addresses these pain points through its LHS240-24 Tension-Rod-Free Fine Wire Drawing Machine, part of a broader product matrix built specifically for the electronic wire and wire cable industry.
Company Background as a Wire Drawing Machinery Manufacturer
Changzhou Dingtian Electrical Machinery Co., Ltd. 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. This range of configurations allows the company to serve customers across different production scales, from precious-metal and specialty-alloy fine wire manufacturers to large cable factories requiring high-capacity output.
The company holds several third-party certifications, including the Quality Management System Certification (GB/T 19001-2016 idt ISO 9001:2015, certificate no. 75424Q0525R0S), the Environmental Management System Certification (GB/T 24001-2016 idt ISO 14001:2015, certificate no. 75424E0248R0S), and the Occupational Health and Safety Management System Certification (GB/T 45001-2020 idt ISO 45001:2018, certificate no. 75424S0219R0S). Dingtian 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.
LHS240-24: A High-Capacity Tension-Rod-Free Solution
Within Dingtian’s slip-type and tension-rod-free fine wire drawing machine lineup, the LHS240-24 is positioned for high-capacity tension-rod-free fine wire drawing with a maximum line speed up to 2,500 m/min. The machine is designed to address several scenario-specific pain points that cable manufacturers commonly encounter: severe tension fluctuation in thicker wires, the need for effective cooling during prolonged high-speed operation, downtime caused by spool changeover, and the pressure to sustain high-volume output.
The LHS240-24 supports a minimum finished wire diameter of 0.10 mm, which enables fine wire drawing for applications that require thinner conductors than standard cable production typically demands. In terms of production efficiency, the machine’s maximum line speed of up to 2,500 m/min translates into measurable output gains. For 0.2 mm finished copper wire, daily output reaches about 2,880 km when running at 2,000 m/min, and about 3,600 km when running at 2,500 m/min. This represents a 25% increase in production capacity under the same process and wire specification, giving manufacturers a clear efficiency benchmark when evaluating equipment upgrades.
Tension Stability and Cooling Enhancements
A defining feature of the LHS240-24 is its enhanced dual-inverter closed-loop slip control, which suppresses tension impact during startup, shutdown, and speed adjustment. This directly addresses the problem of uneven wire thickness that often results from tension spikes during these transitional phases. Beyond tension management, the machine incorporates a reinforced frame that is thickened and fatigue-resistant, supporting round-the-clock uninterrupted production in large cable factories where equipment must withstand continuous mechanical stress.
Cooling and lubrication have also been upgraded on this model. Increased spray flow combined with an enlarged circulation oil tank maintains a stable lubricant temperature, which helps prevent wire oxidation and blackening during extended high-speed runs. These refinements matter for manufacturers concerned about surface quality on finished wire, since oxidation and discoloration are common quality complaints in continuous drawing operations.
Expandability for Automated Production Lines
The LHS240-24 is also built with expandability in mind. It 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 manufacturers moving toward more automated workflows. This connectivity is complemented by support for large-capacity single spools, which reduces downtime associated with spool changeover and improves overall line operational efficiency.
Technical Specifications
The LHS240-24 accepts an inlet wire blank ranging from 0.55 mm to 1.2 mm and produces an outlet finished product between 0.10 mm and 0.40 mm. The machine accommodates a maximum of 24 molds and uses a cone pulley configuration of Φ240×11 sections across 4 sets, paired with a constant speed pulley of Φ240 in 1 set. The main motor is rated at 15 kW, while the take-up motor operates at 5.5 kW. The whole machine weighs 2.13 tons, reflecting its build for sustained industrial-scale operation.
Industry Adaptation and Delivery Model
The LHS240-24 is adapted for large enameled wire factories, power auxiliary material manufacturers, and wire harness producers—industries where consistent high-volume fine wire output is a primary operational requirement. As with other machines in the Dingtian lineup, the LHS240-24 is delivered as an industrial equipment supply with customizable take-up reel dimensions, allowing manufacturers to align the equipment configuration with their existing production setup.
A Manufacturer Focused on Reducing Wire Breakage and Equipment Cost
Across its product range, Dingtian’s stated differentiated advantages include tension-rod-free and closed-loop control designs that reduce wire breakage and improve diameter consistency, along with dual-inverter and full-servo alternatives that balance equipment price and drawing accuracy for different production scales. For manufacturers evaluating an LHS240 drawing machinery factory partner, these characteristics—reinforced construction, tension stability, cooling upgrades, and production-line expandability—position Dingtian’s LHS240-24 as a purpose-built option for cable producers seeking to scale finished wire output while managing tension-related quality risks. The company’s certification portfolio and provincial recognition as a specialized and innovative enterprise further support its standing as an established equipment supplier within the wire and cable manufacturing sector.
