We offer a comprehensive range of precision metal processing equipment, including straightening, cold drawing, pointing, chamfering, cutting, thread rolling machines, and drawing dies, tailored for tube, bar, and wire materials across diverse industries.
The Automatic Hydraulic Cold Drawing Machine is a precision metal forming equipment manufactured by FangRong Precision Machinery, a company with 26 years of expertise in designing, engineering, and producing high-performance cold drawing solutions. Since its founding in 1998, FangRong has grown from a local workshop into a globally recognized manufacturer, serving customers in more than 70 countries.
The Automatic Hydraulic Cold Drawing Machine is a metal processing device that uses hydraulic power to stretch and reduce the diameter of metal materials at ambient temperature. It is designed for the cold drawing of pipes, rods, and profiles made from ferrous and non-ferrous materials, including carbon steel, stainless steel, aluminum, copper, brass, titanium, and specialty alloys. The machine is available in various models with drawing forces ranging from 50KN to 20000KN (approximately 5 to 2,000 tons), accommodating a wide spectrum of production requirements.
Step 1: Material Preparation — The raw material (hot-rolled or extruded tube/bar) is loaded onto the feed rack. One end is pointed (diameter reduced) to pass freely through the drawing die.
Step 2: Die Setup — The material is fed into the die holder, where a precision die shapes the outer diameter. For tube drawing, a mandrel or plug controls inner diameter and wall thickness.
Step 3: Hydraulic Pull — The hydraulic draw carriage, powered by an AC motor-driven hydraulic power unit, pulls the material through the die with smooth, consistent force—eliminating the vibration and surging that cause surface defects in mechanical systems.
Step 4: Intelligent Control — A programmable PLC with intuitive HMI controls the entire drawing cycle: acceleration, constant speed, deceleration, and carriage return. Real-time sensors monitor force, speed, and position, making automatic micro-adjustments to maintain set parameters.
Step 5: Finished Product — The drawn material emerges with improved mechanical properties, precise dimensions, and a superior surface finish—ready for downstream processing or final use.
What Problem It Solves
The machine solves key challenges in metal manufacturing: achieving high mechanical strength, tight dimensional tolerances, and consistent surface quality in high-volume production. Hot-rolled and extruded materials often cannot meet the requirements of applications such as hydraulic cylinders, automotive components, aerospace parts, and medical devices due to limitations in accuracy, surface finish, and material strength. Cold drawing improves material properties through work hardening and grain refinement while achieving dimensional accuracy of up to ±0.02mm. The hydraulic drive system applies controlled, stable drawing force to reduce vibration, prevent surface defects, and maintain consistent quality throughout production.
With more than 20 years of experience in cold drawing technology and thousands of drawbenches supplied worldwide, FangRong has developed solutions for a wide range of materials, including high-strength alloys and high-conductivity copper. This manufacturing experience enables us to design and build cold drawing machines adapted to different material characteristics and production requirements.
1. High-Precision Dimensional Control Advanced hydraulic transmission and closed-loop control systems ensure product diameter accuracy of ±0.02mm, far surpassing industry averages. This ultra-high precision reduces downstream machining requirements, improves sealing performance, and extends product service life.
2. Smooth, Vibration-Free Hydraulic Power Unlike mechanical systems with fixed linkages that can cause jerking and surface defects, the hydraulic system delivers fluid, controlled force from start to finish. This eliminates chatter marks, scratches, and periodic surface imperfections—critical for polished or final-finish components.
3. Wide Material Adaptability Capable of processing carbon steel, stainless steel, alloy steel, aluminum, copper, brass, bronze, titanium, nickel alloys, and specialty metals. By adjusting hydraulic pressure and speed, the machine accommodates different material hardness levels and specifications.
4. Intelligent PLC & HMI Control Programmable logic controller with an intuitive touchscreen interface allows operators to program the entire drawing cycle. Real-time monitoring and automatic adjustments ensure consistent quality with minimal operator intervention, reducing labor requirements.
5. Energy-Efficient Operation Advanced hydraulic design with variable displacement pumps and servo-proportional valves minimizes energy waste. Compared to traditional thermal processing methods, cold drawing saves considerable energy. The system only uses peak power when needed, reducing overall energy consumption.
6. Exceptional Surface Quality Uniform compression and stretching within the precision die produce smooth, flat product surfaces. This high-quality surface reduces grinding and polishing workload in subsequent processing.
7. Extended Tool Life Consistent force application and perfect alignment reduce uneven die wear, extending tool life by up to 30%. The robust construction maintains perfect alignment between the drawing carriage and die holder, crucial for product accuracy and die longevity.
8. Comprehensive Safety Features Two-hand controls, safety light curtains, and interlocked guards protect operators. CE certification ensures compliance with European Machinery Directive 2006/42/EC. Centralized controls and intuitive HMIs simplify operation and reduce setup time.
Our Automatic Hydraulic Cold Drawing Machines are available in a comprehensive range of models to suit diverse production requirements. The drawing force ranges from 50KN to 20000KN, with maximum stroke up to 25 meters and maximum drawing speeds reaching 30m/min.
All models can be customized according to customer specifications, including tube/bar diameters, materials, and production volumes. The machines feature prestressed frame type, fixed bed type, or composite type structures. Hydraulic oil tank capacity typically ranges up to 5000L depending on model. Standard electrical requirements are 380V, 50-60Hz. For ferrous metals and non-ferrous materials alike, we offer tailored solutions to meet your specific dimensional and throughput targets.
