High Precision Straightening Machine

The Inverted Coil Drawing Machine combines continuous drawing and coiling for copper, aluminum, stainless steel, and carbon steel tubes or wires. With drawing speeds up to 400 m/min and tube diameters of 3–25 mm, it reduces cutting, handling, and intermediate storage. Coil drums range from 250–2200 mm. Frequency-controlled speed regulation maintains stable drawing tension and surface quality. Suitable for HVAC, refrigeration, electrical, automotive, and medical tubing production.

The FR-50 Automatic Rack-Pinion Cold Drawing Machine is a 50 kN servo-driven drawbench for precision tube and bar drawing. It uses rack-and-pinion transmission with a 30 kW Inovance servo motor, providing stable speed control and reduced vibration. Suitable for copper, aluminum, stainless steel and carbon steel applications.

The Automatic Crawler-Type Cold Drawing Machine to Coil is designed for continuous drawing and coiling of small-diameter metal tubes. With drawing forces of 10–50 kN and speeds up to 100 m/min, the crawler-track drive provides stable pulling and continuous operation. It handles tube diameters of φ5–40 mm and feeds drawn material directly into the coiler, reducing cutting, handling, and storage. Suitable for copper, aluminum, stainless steel, and carbon steel tubes used in HVAC, automotive, electrical, and general engineering.

The Busbar Hydraulic Drawing Machine is designed for cold drawing copper and aluminum busbars, improving dimensional accuracy, surface finish, and hardness. Drawing forces range from 10–100 tons, with drawing lengths of 6–12 m and speeds of 2–12 m/min. It handles copper busbars from 40×2 mm to 400×30 mm. Hydraulic force control and variable speed provide stable drawing with reduced surface defects. Suitable for power distribution, transformers, switchgear, and electrical equipment.

The Automatic Pointing Drawing Straightening Cutting and Chamfering Line integrates pointing, cold drawing, straightening, cutting, and chamfering into one automated process. With hydraulic push-head forces of 10–300 tons and drawing capacities of 5–200 tons, it processes solid round bars from Ø13–100 mm. Automated transfer reduces labor, handling damage, and pointing waste, while centralized PLC control supports consistent production and traceability. Suitable for carbon steel, alloy steel, stainless steel, copper, and aluminum bars used in fasteners, automotive shafts, bearing rollers, and precision components.

The Four Lines Cold Drawing and Cutting Machine combines cold drawing with automatic fixed-length cutting in one continuous process. It can process 2 or 4 tubes or bars simultaneously, with drawing forces of 10–50 kN and effective strokes up to 7 m. Available in hydraulic, pneumatic, and saw-cutting configurations, it handles carbon steel, stainless steel, copper, aluminum, and alloy tubes or bars up to Ø25 mm. In-line cutting reduces handling and labor while maintaining consistent finished lengths.

The Three Lines Automatic Rotary Cold Drawing Machine is built for manufacturers that need higher drawing output without adding three separate production lines. Its three-strand rotary indexing system positions and feeds three tubes or bars for successive drawing, while the double-chain drive keeps the pulling load balanced across all strands. Models from FR-50 to FR-120 provide 5–20 tons of drawing capacity, speeds up to 28 m/min, and strokes up to 9 m. Automatic feeding, clamping, drawing, and unloading reduce operator involvement and make the machine suitable for carbon steel, alloy steel, stainless steel, copper, and aluminum tubes and bars.

The Automatic Point Pusher Drawing Machine eliminates bar pointing by using a hydraulic push head to feed the full-size bar through the die before the main cylinder takes over. This reduces material loss, tooling, and handling. FR-5T to FR-200T models provide 5–200 tons drawing force and 10–300 tons push force for Ø13–100 mm bars. Suitable for carbon steel, alloy steel, stainless steel, copper, and aluminum.

The Automatic Three Lines Cold Drawing Machine processes three tubes or bars simultaneously, making it suitable for higher-volume production without three separate drawbenches. Its double-chain drive balances the pulling load, while automatic feeding, alignment, clamping, and discharge reduce manual handling. FR-16 to FR-90 models offer 15–160 tons of drawing force, 15 m/min speed, and strokes up to 10 m for steel, copper, aluminum, and alloy tubes or bars.

The Double Chain Cold Drawing Machine is built for high-force drawing where a single pulling chain may create uneven loading on the carriage. Its synchronized dual-chain drive distributes the drawing force more evenly, helping maintain die alignment and stable operation when processing large-diameter, thick-wall, or high-strength tubes and bars. FR-16 to FR-600 models provide 1–300 tons of pulling force, speeds up to 30 m/min, and customizable strokes of 10 m or more. Optional 1–5 strand drawing and automatic feeding, cutting, and receiving support higher-volume production of carbon steel, alloy steel, stainless steel, copper, aluminum, titanium, and specialty alloys.

The Irregular Chain Cold Drawing Machine converts round tubes or solid bars into square, rectangular, hexagonal, octagonal, oval, channel, angle, T-shaped, and custom asymmetric profiles through controlled cold drawing. The chain-driven drawbench provides 7–1000 kN drawing force, speeds up to 28 m/min, and strokes up to 10 m. Multi-strand configurations can draw 1–5 pieces at once, while precision dies control profile dimensions, corner definition, and surface finish. Suitable for carbon steel, stainless steel, alloy steel, copper, aluminum, titanium, and other specialty alloys.
