At Sonnarkraft, powder coating is not just a surface treatment — it’s a production-critical process that impacts product performance, brand image, and compliance. We specialize in automated, high-throughput powder coating solutions tailored for global OEM and Tier 1/2 clients.
What Sets Us Apart：
1. Fully Automated Electrostatic Coating Lines
Equipped with WAGNER (Germany) and GEMA (Switzerland) systems, our lines support steel, aluminum, large-size components, and complex geometries.
2. No Sandblasting Required
We use an Atotech spray-based pretreatment system, offering strong oil-free surface cleaning without abrasive blasting. This ensures high coating adhesion while preserving substrate integrity.
3. Consistent Coating Quality
Digitally controlled powder output and voltage regulation ensure stable film thickness, even color, and superior transfer efficiency across every batch.
4. Supported Part Dimensions
Maximum Part Size: 190 cm (L) × 60 cm (W) × 15 kg
