In many industrial fields such as building steel structures, automobile manufacturing, new energy, warehousing and logistics, standardized C-shaped, Z-shaped, and U-shaped steel can no longer meet the increasingly diverse structural design needs. The application proportion of special-shaped steel components such as complex sections, asymmetric sections, deep bending narrow grooves, and multi-layer reinforcement bars is increasing year by year. At the same time, with the development of lightweight trends in new energy vehicles, the usage of cold-formed steel for bicycles has increased by 30%, and the market demand for high-strength steel precision cold-formed profiles continues to rise. The Customized Cold Roll Forming Machine for Special-Shaped Steel Profiles is a professional equipment designed to meet this market trend – a fully automatic cold bending production line that can achieve 100% personalized customization based on customer drawings and samples.

Customizable types of special-shaped steel for production

This equipment covers customized production needs for various special profiles:

1.Curved and irregular decorative profiles: curved ceiling keel, wavy decorative keel, and curved wall system specific curved adjustable profiles

2.Strengthening and thickening load-bearing profiles: multi fold reinforced load-bearing keel, high-rise fireproof partition wall special keel, seismic thickening special support profile

3.Asymmetric profiles: non-standard opening special profiles, deflection multi angle profiles, and transition connection profiles for complex nodes

4.Multi functional integrated profiles: with cable trough keel, integrated waterproof edge keel, noise reduction and shock absorption decorative profiles

Core advantages：

1. 100% personalized customization, one machine to solve non-standard problems

In high-end commercial buildings, irregular villas, curved ceiling projects, fire partition systems, and special equipment support frames, standard profiles often cannot meet the structural installation requirements. Many customers face difficulties such as inability to find matching molding equipment, poor manual bending accuracy, low efficiency, and serious material waste. This device supports fully personalized customization based on customer drawings, samples, load-bearing data, and on-site requirements. We provide one-stop customized services from profile section design, roller mold development to whole line manufacturing and debugging.

2. Precision molding, excellent quality

The equipment adopts high-precision roll forming technology and is equipped with professional profile simulation design capabilities. Before the equipment is put into operation, professional finite element simulation software is used to analyze the cold bending stress, bending rebound, and metal flow trajectory in advance to ensure successful one-time forming. The core components of the equipment are made of high-quality materials – the rollers are made of GCr15 bearing steel or Cr12MoV mold steel, which have undergone vacuum quenching treatment and have a hardness of HRC58-62, wear resistance, and good toughness. The spindle is made of solid 45 # steel that has undergone quenching and tempering treatment. Some high-end configurations adopt German Copra design and manufacturing technology, known for high efficiency, high precision, and high flexibility.

3. Fully automatic control, efficient production

The equipment relies on a PLC numerical control system to achieve fully automatic continuous operation from unwinding to finished products. The molding speed supports stepless speed regulation from 0-15m/min. Under non punching conditions, some models can achieve a production speed of up to 120 meters per minute, and with the help of a servo online shearing system, the length tolerance can be controlled within ± 0.3mm. The customized equipment adopts a CNC system for precise speed control, and the forming passes are specially adjusted according to the characteristics of the profiles. It can achieve one-time forming of complex curved and multi folded profiles, with strict error control within ± 0.1mm. The user-friendly interface allows one person to monitor and manage the entire production line.

4. Durable and adaptable

The equipment adopts a high rigidity frame structure, with minimal shaking during the molding process and stable finished product dimensions. The core frame undergoes welding aging treatment and does not deform under heavy pressure. Suitable for processing various types of steel such as Q235/Q345. The width range of the processed profile is 80-300mm (expandable according to customized requirements), and the thickness range is 1.5-8mm.

5. Quick change module, flexible changeover

For customized production scenarios that require frequent specification changes, the equipment can be equipped with quick change modules and automated control systems. Through the form of a quick change unit, it is possible to produce a variety of products with different cross-sections and specifications in one machine. Some models support the electric control of the host roller for a 1-minute changeover, greatly improving the overall utilization rate of the equipment.
