Coil to Straight – Caterpillar Drawing Machine with Integrated Cutting Function
FangRong's new caterpillar cold drawing machine starts from a coil rack, passes through the drawing dies, and outputs either coil or straight lengths with integrated cutting – a smart choice for higher capacity and efficiency.
DONGGUAN, China – November 2, 2026 – In our new factory, we are installing the caterpillar cold drawing machine – a structure that differs fundamentally from the traditional coil-type drawing machine. The new system begins with a coil rack, feeds material through the drawing dies, and can output either coil or straight state with an integrated cutting function. For manufacturers looking to increase production capacity and efficiency, the caterpillar structure is a smart choice.
How the Caterpillar Drawing Machine Works
The caterpillar drawing machine uses two continuous, counter-rotating chain tracks to grip and pull the workpiece through the drawing die. Unlike single-pass drawbenches that rely on a reciprocating carriage, the caterpillar design provides continuous motion – enabling higher speeds, smoother surface finish, and true coil-to-coil or coil-to-straight processing.
Key Process Flow
Coil rack – Raw material is loaded as a coil, ready for continuous feeding.
Drawing dies – The material passes through precision dies, reducing diameter and improving surface finish.
Caterpillar traction – Continuous chain tracks grip the workpiece and pull it through the dies without reciprocation.
Integrated cutting – The machine can cut to length directly, outputting straight pieces or continuing in coil form.
Output options – Coil state or straight state, depending on production requirements.
Why Caterpillar Structure for Higher Capacity and Efficiency?
Feature | Benefit |
Continuous drawing | No reciprocating carriage – no idle time between draws |
Higher speeds | Up to 120–300 m/min for non-ferrous materials, depending on configuration |
Coil-to-straight capability | Integrated cutting allows direct output of straight lengths, eliminating secondary operations |
Smooth surface finish | Continuous traction reduces chatter marks and vibration |
Less material handling | Coil input and straight output in one continuous process |
Labor savings | Automated feeding, drawing, and cutting reduce operator intervention |
