A cable tray roll forming machine is an automated industrial production line designed to continuously uncoil, flatten, punch, and shape flat metal strips into U-shaped channels. These finished profiles are used in commercial and industrial construction to support, route, and protect electrical wiring and data cables.

These machines are typically designed to produce two main types of trays:

• Solid Bottom Trays: Standard U-shaped channels with solid bases for maximum cable protection.

• Perforated (Ventilated) Trays: Trays with heavy hole patterns punched into the bottom and sides to allow for airflow and prevent cables from overheating. (Note: Cable “ladder” trays usually require a different type of production line that involves welding individual rungs to side rails.)

Cable trays must support heavy bundles of wire over long spans, so the machines are built to handle structural-grade materials. Common materials include galvanized steel, cold-rolled steel, stainless steel, and aluminum. The typical material thickness ranges from 1.0mm to 2.5mm (or up to 3.0mm for heavy-duty industrial applications).

Because cable trays vary vastly in size (e.g., widths from 50mm up to 1000mm or more), modern machines feature an adjustable duplex (double-sided) or cantilever roll forming design. Instead of swapping out heavy roller dies, the operator uses the motorized control panel to mechanically widen or narrow the distance between the left and right roller stands, allowing for rapid size changes within minutes.

Perforated cable trays require a massive amount of punching. The roll forming line is equipped with a heavy-duty inline mechanical or hydraulic punching press, typically located between the leveler and the roll former. A highly accurate CNC servo feeder pushes the flat metal through the press, which stamps out the complex hole patterns before the metal is folded into its final U-shape.

Because of the heavy, continuous punching required for ventilated trays, these lines generally operate a bit slower than standard roll formers. Average production speeds range from من 10 إلى 15 مترًا في الدقيقة (approx. 33 to 50 feet per minute). If running solid bottom trays without punching, the speed can increase.

تستخدم الآلة hydraulic post-cutting system equipped with a specialized cutting die. This die is custom-machined to perfectly match the U-shape of the finished cable tray (including the side flanges and return lips). When the shear cycles, it cuts through the profile while fully supporting the walls, ensuring the ends are clean, burr-free, and not crushed.

Yes. The entire line—from the servo feeder and punching press to the roll former and cutting shear—is synchronized by an advanced PLC (وحدة التحكم المنطقية القابلة للبرمجة) and a touchscreen HMI. Operators can program the specific batch quantity, the length of each tray, and even the distance between the punched holes. Once set, the machine will run the entire batch completely unattended.
