Door & Window Profile Continuous Coating
Project Background
The client is a leading door & window profile manufacturer in Australia, supplying multiple high-end residential developments. Their line capacity bottleneck caused long order lead times — capacity expansion was urgent.
The Challenge
Door & window profile coating demands extreme color stability and gloss consistency (zero color variation across an order). With 8-12 mainstream colors common, fast color change is essential.
MUSI's Solution
MUSI designed a vertical powder coating line + 8 independent powder hoppers — color change in just 12 minutes. Inline color difference meter samples every 30 m, ensuring color consistency.
Equipment Configuration
| Line type | Vertical powder coating continuous line |
|---|---|
| Profile length | 1.5-6.5 m |
| Hoppers | 8 independent + main hopper |
| Color change time | 12 minutes |
| Conveyor speed | 1.5-3 m/min |
| Annual capacity | 1,000,000 m profile |
| Color difference detection | X-Rite color meter, inline |
| Film thickness | 60-100 μm |
Implementation
90-day delivery. The client's existing line was connected to the new line within 12 hours of stoppage — no impact on continuous production.
Results
New line capacity 80% higher than old. Color consistency pass rate 99.8%. The client won strategic supplier status with multiple top-tier developers.
