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 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 Automatic Crawler-Type Cold Drawing Machine to Coil is designed for manufacturers that need to draw small-diameter metal tubes continuously and receive the finished product in coils instead of straight lengths. It combines a crawler-type drawing system, precision die holder, PLC control and automatic coiling station in one production line, eliminating repeated stopping, unloading, cutting and manual transfer between drawing and coiling operations.
This configuration is particularly useful when the product is supplied in long continuous lengths for downstream tube bending, cutting, heat-exchanger manufacturing or further drawing. The FR series covers tube diameters from φ5 to φ40 mm, with drawing forces from 10 to 50 kN and maximum drawing speeds of 80-100 m/min, depending on the model and process conditions.
Traditional chain or hydraulic drawbenches pull the tube in individual strokes. The Automatic Crawler-Type Cold Drawing Machine to Coil must stop after each stroke so the operator can reset, unload or transfer the workpiece. This operating method is acceptable for short straight tubes, but it becomes inefficient when the customer needs hundreds or thousands of metres of continuous small-diameter tubing.
The crawler system changes the pulling method from intermittent stroke movement to continuous friction pulling. Upper and lower crawler tracks grip the tube over a long contact area and continuously feed it through the drawing die. The finished tube then enters the coiler directly.
The result is not simply a higher drawing speed. The main production advantages are fewer handling steps, less intermediate storage, reduced operator intervention and a finished product format that can be transferred directly to the next process.
When continuous drawing matters: It is most valuable for long-length copper, aluminium and steel tubing where production volume and coil delivery are more important than producing individual straight bars.
When it matters less: If your product is always supplied as short straight lengths and requires frequent changes between very different tube sizes, a conventional drawbench may be more appropriate. Machine selection should therefore be based on material, reduction per pass, finished diameter, required length and delivery format rather than speed alone.
1. Tube feeding: The incoming tube is supplied from a decoiler or straight-length feeding system and enters the machine through the entry guide.
2. Drawing die: The tube passes through a precision drawing die, reducing the outside diameter and controlling the finished dimensional profile. Die design and lubrication have a direct effect on drawing force, surface condition and tool life.
3. Continuous crawler pulling: Two parallel crawler tracks grip the tube before or around the drawing operation. Multiple pairs of pneumatic cylinders apply controlled pressure to maintain friction between the tracks and tube. Unlike a chain drawbench, the crawler does not need to release and reset after each stroke.
4. Variable-speed drawing: Drawing speed is continuously adjustable within the rated range. The actual production speed should be selected according to material strength, tube size, reduction ratio, lubrication and required surface finish rather than simply operating at maximum speed.
5. Synchronized coiling: The drawn tube enters the coiling station immediately after leaving the drawing section. Coiling speed follows the drawing speed to control line tension and produce a stable coil.
6. Coil change: When the preset coil length or production quantity is reached, the control system stops the line for coil replacement and the next spool or drum can be positioned for production.
7. PLC and HMI control: The control system manages drawing speed, length counting, coiling operation and coil-change sequencing, allowing the operator to monitor the complete process from one control station.
The crawler drive provides continuous pulling instead of repeated pull-stop cycles. FR-16 and FR-25 offer drawing speeds up to 80 m/min, while FR-38 reaches up to 100 m/min.
For a high-volume copper tube producer supplying long coils to HVAC manufacturers, this operating principle can remove the downtime associated with repeated drawbench strokes. However, maximum speed is not automatically the best production speed. For difficult stainless steel grades or high reduction ratios, a lower speed with appropriate lubrication may provide better tool life and surface quality.
The crawler contact length ranges from 1800 to 3500 mm. A longer contact area allows the drawing force to be distributed over a greater tube length, reducing the risk of crawler slipping when higher pulling force is required.
This parameter becomes particularly important when processing harder materials, larger tube diameters or higher reductions. For soft copper tube with a modest reduction, the longest crawler is not necessarily required.
The FR series uses multiple air-cylinder pairs to control crawler clamping pressure. FR-16 uses 8 pairs, FR-25 uses 10 pairs and FR-38 uses 12 pairs.
The purpose is to maintain sufficient frictional grip along the drawing zone without relying on excessive pressure at a single point. Correct pressure adjustment is important because insufficient pressure can cause slipping, while excessive pressure can mark or deform the tube surface.
The finished tube is wound directly onto a spool or drum after drawing. This is useful for HVAC, refrigeration and automotive tubing where downstream processes often require long continuous material.
A copper tube producer using an FR-38 for air-conditioning tubing can therefore transfer the finished coil directly to subsequent cutting, bending or heat-exchanger production instead of first cutting the material into straight lengths, bundling it and then feeding it into another process.
The three standard models cover different diameter and drawing-force requirements. Selecting a larger model simply because it offers a higher maximum speed can increase equipment and energy costs without improving production if the required tube size and reduction are small.
| Model | FR-16 | FR-25 | FR-38 |
| Tube Diameter Range | φ5-φ16 mm | φ10-φ25 mm | φ10-φ40 mm |
| Drawing Force | 10 kN | 30 kN | 50 kN |
| Main Motor Power | 15 kW | 22 kW | 37 kW |
| Drawing Speed | 0-80 m/min | 0-80 m/min | 0-100 m/min |
| Air Cylinder Pairs | 8 pairs | 10 pairs | 12 pairs |
| Crawler Width | 80 mm | 100 mm | 120 mm |
| Crawler Contact Length | 1800 mm | 2500 mm | 3500 mm |
| Coiling Station | Integrated | Integrated | Integrated |
Model selection: FR-16 is suited to smaller tube sizes up to φ16 mm; FR-25 provides a higher drawing force for φ10-φ25 mm applications; FR-38 is intended for larger tube sizes up to φ40 mm and applications requiring up to 50 kN drawing force. Final selection should be confirmed from the starting diameter, finished diameter, material grade, reduction per pass, lubrication method and required production output.
Typical materials: Copper and aluminium tubes for air-conditioning coils, refrigeration systems, condensers and evaporators.
Customer scenario: A copper tube manufacturer uses an FR-38 crawler drawbench with integrated coiling to produce long air-conditioning tubing. The continuous drawing process allows the drawn tube to enter the coiler directly, reducing the need for intermediate cutting and manual transfer before the next production operation.
For this application, drawing speed and coil stability are usually more important than maximum drawing force alone. Lubrication, die condition and final dimensional tolerance should be evaluated together with output requirements.
Typical materials: Carbon steel, stainless steel, copper and aluminium tubing for brake lines, fuel systems and vehicle air-conditioning systems.
Customer scenario: An automotive tubing supplier uses an FR-25 for continuous production of coiled small-diameter tubing. The crawler pulling system avoids the repeated acceleration and deceleration associated with intermittent drawing, helping the producer maintain a more stable continuous process before downstream cutting and forming.
For automotive tubing, surface condition and dimensional consistency may be more important than achieving the highest possible line speed because defects can become costly after bending, flaring or assembly.
Typical materials: Stainless steel and other precision alloys used for small-diameter tubing and instrumentation components.
Customer scenario: A medical-device manufacturer uses an FR-16 to draw small-diameter stainless steel tubing for subsequent cutting and assembly. The continuous process is suitable when long, consistent tube lengths are required before the material is cut into individual components.
For medical and instrumentation applications, maximum speed is usually less important than dimensional control, surface condition, tooling stability and traceable quality inspection.
Small copper, aluminium and steel tubes can be drawn and coiled for electrical components, instrumentation, heat-transfer components and other engineered products. The integrated coiling configuration is most useful where the next process can accept continuous coil material.
The standard machine package includes the crawler drawing system, main motor, gearbox, die holder, pneumatic clamping system, integrated coiling station, PLC control cabinet with HMI and standard machine components.
Drawing dies for specific tube sizes are normally selected according to the customer's material and pass schedule and can be quoted separately. Decoilers, additional feeding equipment, special coiling drums, customized automation and other upstream or downstream equipment can be configured according to the production line.

The Automatic Crawler-Type Cold Drawing Machine to Coil is prepared for international shipment with export-oriented packaging and protection for mechanical, electrical and pneumatic components. The final packing method depends on machine dimensions, shipping route and whether the equipment is shipped as a complete machine or in separated sections.
For overseas projects, the packing list, machine dimensions, gross weight and loading arrangement are confirmed before shipment so the buyer can prepare customs clearance, inland transportation and factory unloading equipment in advance.
Start with the actual tube diameter and drawing force rather than maximum speed. FR-16 covers φ5-φ16 mm and provides 10 kN; FR-25 covers φ10-φ25 mm and provides 30 kN; FR-38 covers φ10-φ40 mm and provides 50 kN. Material strength, starting diameter, finished diameter and reduction per pass should also be considered.
Yes, the FR series can be configured for copper, aluminium, stainless steel, carbon steel and selected specialty alloys. However, the same machine should not be assumed to use identical dies, lubrication or drawing parameters for every material. Harder materials generally require more drawing force and closer control of reduction and lubrication.
No. 100 m/min is the maximum rated speed of FR-38 under suitable process conditions. Actual production speed depends on material, tube dimensions, reduction, die design, lubrication, surface requirements and coiling conditions. Running at the maximum speed is useful only when the complete process can maintain stable quality at that speed.
The main difference is the pulling method. A conventional drawbench pulls in strokes, while the crawler system provides continuous friction-based pulling. This is advantageous for long continuous tubes because it reduces stop-start cycles and allows the drawn product to enter the coiler directly.
Proper crawler pressure, track condition, alignment and process lubrication are important. Excessive clamping pressure can damage sensitive surfaces, while insufficient pressure can cause slipping. The clamping system therefore needs to be adjusted according to tube material and surface requirements rather than simply applying maximum pressure.
Please provide the material grade, starting tube diameter, finished diameter, tube wall thickness if applicable, required drawing speed, target production output, coil dimensions and available power supply. A drawing sample or existing pass schedule is also useful. These parameters allow the required drawing force and machine model to be checked before quotation.
The standard machine includes the drawing system and die holder. Dies for specific tube sizes are selected according to the customer's material and dimensions and are normally quoted according to the required drawing process.
Yes. The FR-series configuration includes an integrated coiling station. The coiler follows the drawing line speed and winds the finished tube onto the specified spool or drum. Coil length, tension and changeover requirements should be confirmed during technical specification.
The standard MOQ is 1 complete machine set. Quantity-based quotations can be prepared for 1 set, 2-4 sets and 5+ sets. The final unit price depends not only on quantity but also on the selected model, tooling, coiling configuration, automation and customer-specific requirements.
The standard FOB quotation is based on Shenzhen Port, China. If your logistics arrangement requires another Chinese port, the shipping term and inland transportation cost can be recalculated in the quotation.
