1. Typical Production Line Configuration

A complete cable tray roll forming system usually consists of the following modules:

1) Decoiler (Uncoiler)

Holds and feeds metal coils into the line

Often hydraulic for heavy coils

2) Leveling & Feeding Unit

Flattens the strip for accurate forming

Ensures consistent thickness and stress removal

3) Punching System

Creates holes for:

Cable ventilation

Mounting

Weight reduction

CNC/servo punching for flexible patterns

4) Roll Forming Machine (Core Unit)

Multi-station rollers gradually form the tray profile

High precision and repeatability

5) Cutting System

Hydraulic or flying shear cutting

Cuts to preset lengths without stopping the line

6) Output & Stacking

Automatic discharge and stacking system

This continuous process (uncoiling → punching → forming → cutting) enables high-speed, mass production with minimal labor.

3. Types of Cable Tray Roll Forming Systems

• Standard Cable Tray Line

· Produces solid bottom trays

· Basic industrial applications

• Perforated Cable Tray Line

· Integrated punching system

· Most common for ventilation and weight reduction

• Ladder Cable Tray Line

· Produces side rails + rungs

· Often requires additional assembly equipment

• Heavy-Duty vs Light-Duty Machines

· Light-duty: thinner material, smaller width

· Heavy-duty: thicker material, higher load capacity

4. Key Advantages

· High efficiency – continuous production vs press brake

· Consistency – uniform profile and dimensions

· Automation – PLC control reduces labor

· Material savings – optimized forming process

· Flexibility – quick changeover for different tray sizes

5. Working Principle (Simple Explanation)

· The system uses cold roll forming, where:

· A flat metal strip passes through multiple rollers

· Each roller gradually bends the material

· Final shape is achieved without heating
