The CRM Shaped Wire Drawing System from Sky Bluer is a complete solution for manufacturing high-precision shaped wire from round wire. Unlike conventional wire drawing machines, this integrated production system combines multi-pass wire drawing, precision profile rolling, final sizing, and tension control to produce flat, rectangular, square, trapezoidal, wedge, keystone, sector, and other custom wire profiles with excellent dimensional accuracy and surface quality.
The profile rolling unit is an important forming stage within the production line rather than the final process. By combining precision drawing with controlled profile rolling and final sizing, the CRM system delivers superior profile consistency, stable mechanical properties, and high production efficiency. It is widely used for manufacturing shaped wire for electric motors, transformers, medical devices, electronics, filtration systems, aerospace components, welding materials, and other precision industrial applications.
What Is a Shaped Wire Drawing System?
A shaped wire drawing system is an integrated production line designed to convert round wire into precision profile wire through a sequence of drawing, rolling, calibration, and sizing operations. Unlike a standalone profile rolling machine, the CRM system performs diameter reduction during multiple drawing passes before gradually forming the required cross-sectional profile through a precision four-roll profile rolling unit. Final sizing with a Turks Head ensures excellent dimensional consistency and surface finish.
This manufacturing process minimizes residual stress, improves profile accuracy, and enhances mechanical properties compared with conventional profile forming methods. The modular design also allows manufacturers to configure different production capacities, wire materials, and profile geometries according to specific application requirements.

Precision Profile Rolling Unit
The profile rolling unit is the core forming section of the CRM Shaped Wire Drawing System. Instead of creating the profile directly from large-diameter wire, the rolling unit receives accurately drawn wire and gradually forms the required cross-section with minimal deformation.
The CRM Universal Profile Rolling Machine features a four-roll adjustable structure that distributes forming pressure evenly around the wire. Compared with conventional two-roll systems, the four-roll design provides better profile symmetry, reduced material stress, improved dimensional stability, and higher production repeatability.
Each roll can be adjusted independently in both radial and axial directions, allowing operators to fine-tune profile dimensions without replacing the complete roller assembly. This significantly reduces setup time and improves production flexibility.
Universal Four-Roll Profile Rolling Machine
The CRM Universal Profile Rolling Machine is suitable for producing a wide variety of standard and custom wire profiles.
| Feature | Specification |
| Rolling Structure | Universal Four-Roll |
| Roller Diameter | 45–550 mm |
| Roll Position Adjustment | Radial + Axial |
| Roll Type | Driven or Undriven |
| Roller Material | High-Speed Tool Steel or Carbide |
| Lubrication | Automatic or Manual |
| Cooling | Water Cooling System |
| Applications | Flat, Square, Rectangular and Custom Profiles |
The modular rolling cassette enables rapid roller replacement while maintaining precise alignment, making it ideal for manufacturers producing multiple wire profiles in small or medium production batches.
Undriven Turks Head for Final Sizing
After profile rolling, the wire passes through the CRM Undriven Turks Head for final sizing and geometry correction. This unit provides precise calibration of profile dimensions while improving straightness and surface finish. It is especially effective for flat wire, rectangular wire, and square wire production where tight dimensional tolerances are essential.
The universal four-roll Turks Head allows one standard roll set to process multiple profile sizes, reducing tooling costs and minimizing production downtime.
