The High-Speed Cable Tray Roll Forming Machine | Custom Sizes & Automatic Cutting is an automated cold bending equipment designed specifically for metal coils such as galvanized steel strip, cold-rolled steel strip, and stainless steel strip. It integrates multiple processes such as unwinding, leveling, punching, cold bending, cutting to length, and palletizing into one production line, achieving continuous automation of the entire process from “steel coil in” to “finished product out”.

This production line can produce various types of cable trays such as trough type, ladder type, and tray type, suitable for a wide range of specifications including tray width of 100-800mm and height of 50-200mm. The material thickness can cover 0.8-3.0mm. The entire line adopts PLC programmable controller and touch screen operation interface, supports multi specification parameter storage and one click switching, and is the core equipment for cable tray manufacturing enterprises to achieve large-scale and flexible production.

 Scientific and rigorous process flow：

The fully automatic cable tray cold bending production line follows a standardized and systematic process flow:

Uncoiling and feeding → Multi roll leveling → Servo feeding → Precision punching (connection/installation holes) → Multi pass cold bending forming → Cut to length → Discharge and palletizing

The entire process is interconnected and seamlessly connected. among which

1.Uncoiling unit: equipped with heavy-duty feeding racks, tension control, and correction devices, suitable for heavy-duty raw material coils, ensuring smooth unwinding without deviation;

2.Leveling unit: Multiple sets of high-precision leveling rollers are used to correct the wave patterns and warping of raw materials, ensuring a smooth and wrinkle free surface of the bridge after forming;

3.Punching unit: using a hydraulic punching system to achieve precise punching of connection holes, installation holes, and other hole positions;

4.Forming host: core component, designed with multiple forming rollers according to the cross-sectional shape of the bridge, gradually rolled into shape through cold bending process;

5.Cutting unit: Cut using hydraulic or flying saw, with a smooth and burr free cut.

The final finished cable tray has excellent qualities such as precise size, smooth surface, and reliable strength, and can be directly used in various cable laying projects.

 Core advantage: Five dimensions define new industry benchmarks：

1. Efficient production capacity, significantly improving production efficiency
The molding speed of the production line can reach 10-30 meters per minute, with continuous automated operation. A single shift can produce several kilometers of cable trays. Some high-end models can achieve a molding speed of 16 meters per minute and an hourly production capacity of over 500 meters. Calculated based on a single 8-hour shift, it can meet the urgent demand for large-scale engineering batch supply and completely bid farewell to the inefficient bottleneck of traditional processing.

2. Precision molding, stable and reliable quality
The production line adopts a multi pass progressive cold bending process, with up to 18-28 forming rollers. Through gradual rolling, the metal sheet is accurately formed into bridge profiles. The forming roller is made of GCr15 bearing steel material, which has been quenched and hardened to a hardness of HRC56-62. The entire line is equipped with a high-precision servo control system, and the width and height dimension errors of the bridge can be controlled within ± 0.3mm. Some high-end equipment can achieve an accuracy of ± 0.05mm. The wall thickness is uniform, the groove body is regular, and the splicing is tightly fitted, ensuring the stability and consistency of the bridge installation.

3. One machine for multiple uses, flexible changeover saves time and effort
In traditional production methods, different specifications of bridge frames often require the replacement of different rollers and molds, which is time-consuming and labor-intensive. The modern cable tray cold bending forming line adopts a combination adjustable structure, and a set of rollers can cover the production of various specifications of cable trays. The specification changes only need to adjust the gear of the forming machine and the rollers to complete. Some advanced models also support automatic adjustment of width and height through motors, with a minimum changeover time of 15-30 minutes. This flexible design of “one machine for multiple uses” significantly reduces equipment investment costs and enhances the flexibility of production scheduling.

4. Reduce costs and increase efficiency, with significant investment returns
Automated production significantly reduces the demand for manual labor – traditional production methods require multiple operators to work together, while automated production lines only require 1-2 people to complete full line control. The total installed power of the entire line is about 40-95kW, with controllable energy consumption and low failure rate. The high utilization rate of materials significantly reduces the labor costs and raw material losses of the enterprise. At the same time, the equipment has a stable structure, smooth operation, low maintenance requirements, and outstanding comprehensive cost-effectiveness advantages for long-term production.
