PAINT & COATING LINE
PXID’s coating line includes pre-treatment, powder coating, curing ovens, and water-transfer labeling.
Automated control systems and cleanroom-grade spray environments ensure uniform coating thickness, high adhesion, and consistent durability. Both aluminum and steel frames achieve stable, high-quality finishes with long-term corrosion resistance and excellent surface appearance.
Pre-Treatment Process
Before coating, frames undergo meticulous surface preparation. Polishing removes surface imperfections, followed by degreasing, alkaline etching, and chromating to create a dense protective layer. This significantly enhances powder-coat adhesion and corrosion resistance, forming a reliable foundation for premium finishing quality.
Film & Primer Curing Ovens
After pre-treatment, frames enter film-curing and primer-curing ovens. Precise temperature control ensures full curing of the protective layer and primer, preventing issues such as color inconsistency, peeling, or dullness. This stage builds the essential corrosion-resistant base for the final coating.
Topcoat Spraying & High-Temperature Curing
The topcoat provides the frame’s final visual finish. After spraying, frames enter a high-temperature curing oven for complete cross-linking and adhesion. The cured surface offers high gloss, color stability, and strong impact resistance, remaining vibrant even under long-term outdoor exposure.
Cleanroom-Grade Powder Coating Line
The powder-coating line operates with cleanroom-level air filtration to eliminate dust contamination. High-quality powder materials ensure strong adhesion, uniform thickness, and excellent wear resistance. The resulting coating withstands scratches, moisture, and chemical exposure, maintaining long-term appearance stability in all climates.
Water-Transfer Decals & Protective Coating
The water-transfer process enables precise placement of logos and graphics. After positioning and shaping, a protective clear coat is applied to enhance scratch resistance, waterproofing, and long-term adhesion. This ensures lasting brand visibility and a premium appearance.
Automated Conveyor Coating Line
The automated conveyor system moves frames through each stage smoothly, minimizing handling damage and contamination. Automatic adjustments optimize height and speed for different frame types, improving coating consistency and overall efficiency.
Cleanroom-Grade Air Filtration System
Multi-stage filtration maintains stable humidity and ultra-low particle levels. This prevents defects such as dust spots, streaks, and bubbles, ensuring a flawless surface texture and premium finish quality.
High-Quality Coating System
A high-end coating system not only elevates product aesthetics but also provides long-term protection—making it a critical part of ODM product reliability.
