Automatic Cable Tray Roll Forming Machine | PUTAI, Tianjin, China

PUTAI Automatic Cable Tray Roll Forming Machine – Made in Tianjin, China

The PUTAI automatic cable tray roll forming machine is an integrated production line for manufacturing steel cable trays used in electrical, data and communication installations. Built at PUTAI's factory in Tianjin, China, the line takes steel coil from 0.7 to 1.2 mm and levels, punches, forms and cuts it in one continuous process. A flying cut-off shears each tray to length without stopping the line, and every metre comes out with identical dimensions for a perfect fit on site, replacing slower press-brake production with a faster, lower-cost automatic process.

What Is a Cable Tray?

• A formed steel support system that carries and protects power, data and communication cables
• Keeps cables organised, ventilated and easy to access for maintenance
• Punched holes and slots allow ventilation, cable ties and bolted connections
• Used throughout commercial buildings, industrial plants, data centres and utility projects

Why Roll Forming Instead of a Press Brake?

• Continuous production: Runs directly from coil, with no sheet cutting or manual handling between steps
• Consistent quality: Every tray has identical dimensions and profile, so sections fit together cleanly on site
• Lower labour cost: One line replaces several press-brake and punching operations
• Less waste: Trays are cut to exact lengths straight from coil

Key Features

• Complete integrated line from coil to finished tray
• Inline hydraulic or servo punching for holes, slots and notches
• Flying cut-off synchronised with the moving tray for clean, burr-free cuts without stopping
• 22 forming stations for accurate side walls and flanges
• Entry guide and levelling unit keep the strip flat and aligned to prevent twist
• PLC control for tray length, quantity and hole patterns
• 32.5 kW drive power for heavy-duty continuous running
• 60 mm 40Cr steel shafts for rigid, accurate forming
• Graduated adjusting nuts for precise, repeatable roller setup

Frequently Asked Questions

• Where is this machine made? It is manufactured by Tianjin PUTAI Technology Co., Ltd at its factory in Tianjin, China, and exported worldwide.
• What thickness can the machine form? Steel from 0.7 to 1.2 mm.
• Does it punch the trays in line? Yes. The punching and notching unit creates holes, slots and notches as part of the continuous line.
• Does the line stop to cut? No. The flying cut-off moves with the tray and cuts without stopping, giving clean, burr-free edges.
• How fast does it run? Up to 15 m/min, depending on thickness and punching pattern.
• Why choose roll forming over press-brake production? It is faster, more consistent, needs less labour and wastes less material.
• How long is delivery? Around 60 days.
• What should I send for a quotation? Your tray drawings with width, height and hole pattern, thickness, material type, target output, and local voltage and frequency.
