Meeting High-Volume Fine Wire Demand at an LHS240 Drawing Machinery Factory

Wire and cable manufacturers seeking a dependable LHS240 drawing machinery factory increasingly look toward Changzhou Dingtian Electrical Machinery Co., Ltd., a manufacturer of wire drawing machines for the electronic wire and wire cable industry. Operating under the brand name Dingtian, the company supplies precision ultra-fine and fine wire drawing equipment with servo, slip-type, tension-rod-free, and in-line continuous annealing configurations. This positioning directly addresses a well-known industry pain point: mechanical tension fluctuation that causes wire breakage and diameter variation, combined with the high equipment procurement cost typically associated with international suppliers.

The LHS240-24 Tension-Rod-Free Fine Wire Drawing Machine

Among Dingtian's product line, the LHS240-24 Tension-Rod-Free Fine Wire Drawing Machine stands out as a high-capacity solution built for manufacturers that need consistent, large-scale fine wire output. The machine is positioned as a high-capacity tension-rod-free fine wire drawing system with a maximum line speed up to 2,500 m/min.

Target Scenario Pain Points

The LHS240-24 was engineered around four recurring challenges reported across the wire drawing industry:

  • Severe tension fluctuation in thicker wires
  • Cooling difficulties during prolonged high-speed operation
  • Spool changeover downtime
  • The need for high-volume output without sacrificing wire quality

Differentiated Value

Dingtian's engineering approach to the LHS240-24 translates these pain points into measurable advantages:

  • Fine wire processing: The machine supports a minimum finished wire diameter of 0.10 mm, enabling reliable fine wire drawing.
  • Production efficiency: With a maximum line speed up to 2,500 m/min, daily output for 0.2 mm finished copper wire reaches about 2,880 km at 2,000 m/min and about 3,600 km at 2,500 m/min, representing a 25% increase in production capacity under the same process and wire specification.
  • Tension stability: An enhanced dual-inverter closed-loop slip control system suppresses tension impact during startup, shutdown, and speed adjustment, avoiding uneven wire thickness.
  • Expandability: The LHS240-24 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 building out full production capability.

Key Features Built for Continuous Operation

The LHS240-24 incorporates several structural and functional features designed for round-the-clock manufacturing environments:

  • A reinforced frame that is thickened and strengthened with fatigue resistance, supporting round-the-clock uninterrupted production in large cable factories.
  • Upgraded cooling and lubrication, including increased spray flow and an enlarged circulation oil tank, which maintains stable lubricant temperature and prevents wire oxidation and blackening.
  • Support for large-capacity single spools, which reduces downtime associated with spool changeover and improves overall line OEE.

Technical Highlights

For manufacturers evaluating equipment specifications, the LHS240-24 offers the following technical parameters:

  • 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 offered through an industrial equipment supply model with customizable take-up reel dimensions, allowing buyers to tailor spool specifications to their production line requirements.

Industry Adaptation

The LHS240-24 is designed to serve large enameled wire factories, power auxiliary material manufacturers, and wire harness producers—segments that typically require sustained high-speed output combined with tight tension control.

Why Dingtian's Broader Capability System Supports This Machine

The LHS240-24 does not operate in isolation; it is backed by Dingtian's wider technology platform and quality infrastructure. The company applies full-servo systems with customized Inovance servo components for tension control, dual inverter plus PLC control for synchronized wire drawing and take-up, tension-rod-free slip control with closed-loop constant tension control, and in-line continuous annealing with DC three-stage annealing and saturated steam isolation across its product range. These platform-level capabilities inform the tension management logic used in the LHS240-24's dual-inverter closed-loop slip control.

Quality assurance is formalized through certification. Dingtian holds Quality Management System Certification under GB/T 19001-2016 idt ISO 9001:2015 (certificate no. 75424Q0525R0S, 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 from April 2024 to April 2027.

On the technical development side, Dingtian holds utility model patents including a reel driving mechanism and wire drawing machine (patent no. ZL202322744129.0, publication no. CN220787693U) and a cooling mechanism for a dual variable frequency micro-fine wire drawing machine (patent no. ZL202323066979.6, publication no. CN221086758U). These innovations reflect the same engineering focus—stable reel driving and effective cooling—found in the LHS240-24's design.

Service and Delivery Support

Beyond equipment supply, Dingtian offers customized equipment configuration and process parameter optimization, after-sales service and technical support, and wire trial verification at its own facility. Its service scope covers equipment customization, process commissioning, production support, after-sales support, and equipment appearance customization according to customer branding requirements. For factories bringing an LHS240-24 into an existing line, take-up reel dimensions can be customized according to customer needs, and the machine's expandable design allows straightforward connection with pay-off, annealing, and take-up units already in place.
