In modern metal forming, automotive manufacturing, new energy, and high-end industrial component production, ordinary round wire can no longer meet the demands of compact structure, high mechanical strength, and customized cross-sectional geometry. High-precision flat wires, rectangular wires, square wires, wedge and triangular profile wires have become indispensable core raw materials for high-end manufacturing.
As a newly upgraded high-precision cold rolling production line launched by Sky Bluer Environmental Technology Co., Ltd, the CRM-2024 Wire Flattening & Shaping Lines is engineered to convert round metal wires into diversified flat and profiled finished products. It integrates precision cold rolling, real-time online dimension monitoring, nitrogen-protected annealing, and full closed-loop servo control, solving long-standing industry pain points such as unstable tolerance, inconsistent surface quality, limited material adaptability, and low automation in traditional wire flattening equipment.
What Makes CRM-2024 Stand Out in Precision Cold Rolling
Traditional wire flattening equipment mostly adopts open-loop manual adjustment, relying heavily on operator experience. It is prone to dimensional deviation, edge burrs, uneven thickness, and obvious batch-to-batch differences—especially difficult to process high-hardness alloys such as stainless steel, titanium and nickel-titanium alloys.
The CRM-2024 series is built for high tolerance consistency, multi-material compatibility, and full-process intelligent control. It adopts imported contact thickness and width online measurement systems, coupled with Siemens and Beckhoff industrial controllers, realizing real-time collection, automatic compensation and dynamic adjustment of dimensional data throughout the whole line. Combined with nitrogen-sealed annealing technology, it effectively eliminates rolling residual stress, optimizes internal metal grain structure, and balances ductility, tensile strength and surface finish of the finished wire.

Core Technical Advantages & Key Functional Highlights
1. Full Closed-Loop Precision Control System
Equipped with high-end industrial PLC, human-machine touch screen and full servo drive configuration, the line supports one-click parameter setting and automatic operation. The online high-precision diameter measuring instrument continuously tracks width, thickness and straightness, feeding data back to the rolling system in real time for micro-adjustment. It achieves a stable tolerance of ±0.001mm, supporting further customized tolerance requirements for ultra-precision scenarios.
2. Diversified Profile Forming Capability
Unlike ordinary flattening machines that only produce simple flat wires, CRM-2024 supports one-time forming of multiple complex cross-sections:
- Flat wire / rectangular wire / square wire
- Wedge wire / triangular wire
- Custom special-shaped profile wires
It meets the personalized shaping needs of automotive structural parts, spring materials, connectors and industrial special alloy wires.
3. Ultra-Wide Material Compatibility
The production line is compatible with almost all ferrous and non-ferrous metals:
- Carbon steel: low-carbon, medium-carbon, high-carbon steel
- Stainless steel: conventional and duplex grades
- High-performance alloys: titanium, nickel-titanium alloy
- Non-ferrous metals: copper, aluminum, brass
Through optimized roller material matching and rolling reduction gradient design, it avoids work hardening, edge cracking and surface scratching during cold rolling of high-strength brittle alloys.
4. Flexible Production & Intelligent Operation Modes
CRM-2024 supports automatic / manual press-down dual modes, adapting to mass continuous production and small-batch customized trial production. It can be configured as single-stage flattening or multi-stage tandem rolling lines, greatly improving production efficiency and process rationality for large-volume factories.
The precision arranging and take-up system ensures neat winding, no loose coils or overlapping layers, facilitating downstream annealing, tinning, stamping and deep processing.
5. Optional Integrated Auxiliary Systems
To build a one-stop forming solution, the line can be expanded with optional modules:
- Automatic pay-off & precision take-up unit
- High-precision laser online measuring system
- Centralized automatic lubrication system
- Professional wire guide and straightening device
All modules are seamlessly matched with the main line, reducing manual intervention and lowering long-term maintenance costs.
