Problems Before Machine Installation

Before installing the new roll forming machine, the factory experienced several major challenges:

1. Outsourcing Dependency

• Relied on third-party suppliers for panels
• Long lead times
• Inconsistent quality and pricing

2. Limited Production Capacity

• Older equipment could only produce ~12,000 meters/day
• Unable to meet demand

3. Quality Issues

• Oil canning (panel waviness)
• Inconsistent rib height
• Poor cut accuracy

4. High Labor Costs

• Manual handling required large workforce
• Increased risk of human error

5. Lack of Flexibility

• Limited ability to produce custom panel lengths
• Slow response to urgent orders

Problems Solved After Implementation

1. Full In-House Production

The factory eliminated outsourcing and gained full control over manufacturing.

2. Increased Production Speed

The new machine doubled production capacity, allowing continuous high-speed operation.

3. Improved Product Quality

Precision tooling ensured:

• Consistent panel shape
• Accurate dimensions
• Reduced defects

4. Reduced Labor Costs

Automation reduced workforce requirements by approximately 40%.

5. Faster Turnaround Times

• Improved customer satisfaction

Production Workflow

The factory operates a streamlined, continuous production process:

Step 1: Coil Loading

Steel coils are loaded onto a hydraulic decoiler with controlled tension.

Step 2: Feeding and Alignment

Material is guided into the roll forming machine using entry guides.

Step 3: Roll Forming

The steel passes through 24 roller stations, gradually forming the PBR profile.

Step 4: Cutting

A hydraulic shear cuts panels to precise lengths based on PLC settings.

Step 5: Stacking

Finished panels are automatically stacked for packaging and shipping.

Common Production Issues & Solutions

Oil Canning (Panel Waviness)

Cause: Incorrect roll pressure or poor material quality
Solution: Adjust roll gaps and use higher quality coils

Cut Length Errors

Cause: Encoder misalignment
Solution: Recalibrate encoder and verify PLC settings

Rib Deformation

Cause: Tooling misalignment
Solution: Realign roller stations and inspect tooling

Surface Scratches

Cause: Worn rollers or contaminated guides
Solution: Replace components and clean system regularly

Maintenance Strategy

Daily:

• Visual inspection
• Clean rollers and guides

Weekly:
