Corrugated sheets: ~6,000–10,000 meters/day

Key Insight:

Separating production by product type allowed:

Higher efficiency
Faster turnaround
Reduced operator errors

Key Challenges Faced

1. Oil Canning on Roofing Panels

Issue:

Visible waviness on flat sections of panels

Cause:

Improper roller pressure
Heat expansion during summer

Solution:

Adjusted forming pressure
Reduced machine speed in high heat
Improved setup consistency

2. Long Panel Handling

Issue:

Panels bending or getting damaged during handling

Cause:

Insufficient support
Manual handling errors

Solution:

Installed runout tables and supports
Improved stacking systems

3. Seasonal Demand Fluctuations

Issue:

High demand during planting and harvest seasons

Solution:

Increased production before peak seasons
Maintained buffer stock

4. Material Variability

Issue:

Different coil batches caused inconsistencies

Solution:

Standardized suppliers
Checked coil specifications before production

5. Dust and Environmental Conditions

Issue:

Dust affecting surface finish and machine performance

Solution:

Regular cleaning
Covered storage areas

Production Performance

Quality Results:
