Cable Tray Roll Forming Machine
The cable tray cold bending forming machine is the core rolling equipment in the cable tray production line, used to continuously roll steel strips into trough, tray, and trapezoidal cable tray profiles. Width is electrically adjustable from 100-600mm, one set of rollers covers all specifications, and production changeover is quick in 10 minutes. It features Cr12 hardened rollers (HRC58°-62°), 20 sets of rollers, a speed of 10-15m/min, suitable for 1-3mm thick plates, and optional ribs. It is universal for all three types of cable trays.

Product Advantages
I. Ribbing Function Activated on Demand, Same Roll Adapts to Different Load-Bearing Requirements
Ribping at the bottom and sides of the cable tray enhances its load-bearing capacity, but ribs are unnecessary in some light-load applications. The equipment simultaneously forms the ribs during the rolling process. Customers can select ribbed or unribbed sections via a touchscreen, eliminating the need to change rollers. The same set of rollers can produce both ribbed and unribbed cable trays, flexibly meeting diverse order demands.
II. Three Types of Cable Trays Share One Roll, No Secondary Changeover Required
Trough-type, tray-type, and trapezoidal-side cable trays have different cross-sections, traditionally requiring frequent changes of three sets of rollers. This equipment, through split adjustment and roller combination switching, allows one set of rollers to cover the production of all three profiles. Switching only requires calling the corresponding parameters and activating the relevant function module, without disassembling or replacing rollers, significantly reducing changeover time and mold investment.
III. 20-Pass Progressive Forming, No Corner Cracking for 2-3mm Thick Plates
Thick plates (2-3mm) commonly used in cable trays are prone to corner cracking during bending. The equipment is equipped with 20 sets of rollers, which evenly distribute the total deformation to each pass, completing the process step by step from pre-bending and forming to finishing, avoiding stress concentration caused by large-scale bending at once. After forming, the corners of the cable tray are intact without cracks, the cross-sectional dimensions are stable, and the mechanical strength meets the requirements for heavy-duty use.

FAQ
Q: Are you a factory or a trading company?
A: We are a factory located in Weifang, China. It possesses over twenty sets of advanced equipment, including a new precision machining center, NC lathes, CNC wire EDM machines, and a large automotive profile bending test platform. You are welcome to visit our factory at any time.
Q: Does switching between ribbed and non-ribbed plates require machine shutdown?
A: No. The ribbed function is performed by independent rollers. Simply select ribbed or non-ribbed on the touchscreen for automatic switching; no machine shutdown or roller replacement is required.
Q: How long does it take to switch between the three types of cable trays?
A: For pallet-type production, the pallet hole punching system needs to be activated; for trapezoidal-edge production, the trapezoidal-edge forming function needs to be enabled. Switching takes approximately 20-30 minutes and does not require replacing the entire set of rollers.
Q: What are the advantages of a 20-pass machine compared to a machine with fewer passes?
A: More passes result in less deformation per pass, a smoother forming process for thick plates, more complete stress release, less corner cracking, less springback, and higher finished product precision and straightness.
