Electrostatic Powder & Small-Part Coating
Electrostatic powder coating on our horizontal line for profiles up to 7,000 mm as well as finished, cut-to-size machined components (Small-Part Coating).
Multi-Stage Chemical Pre-Treatment and 7,000 mm Horizontal Line
Long-term adhesion and corrosion resistance in architectural powder coating depend on chemical pre-treatment. Before entering the spray booth, profiles undergo degreasing, etching and conversion coating.
Our horizontal line coats profiles up to 7,000 mm across the full RAL palette in matt, gloss, fine-texture (sablé) and metallic effects at 60–80 µm film thickness, cured at approximately 200 °C.
Engineering Comparison: Powder Coating vs. Anodizing
Selecting the right surface finish depends on color requirements, wear environment and section geometry. The table below compares both in-house technologies.
| Engineering Criterion | Electrostatic Powder Coating (RAL) | Anodizing (DIN 17611) |
|---|---|---|
| Coating Mechanism | Thermoset polyester organic polymer film | Integral electrochemical Al₂O₃ oxide conversion |
| Standard Film Thickness | 60 – 80 µm | 10 – 12 µm (15–25 µm for heavy architectural use) |
| Maximum Profile Length | 7,000 mm (horizontal line) | 7,000 mm (8,000 × 2,500 mm bath) |
| Color & Texture Range | Full RAL palette, matt, gloss, fine texture, metallic | Silver, gold, champagne, bronze, brown, black (E0–E6) |
| Die-Line Masking Ability | High (60–80 µm film masks minor extrusion lines) | Transparent (preserves metallic grain; uses E1–E6 prep) |
| Local Touch-Up Capability | Can be locally touched up on site if scratched | Cannot be spot-repaired; requires stripping & re-anodizing |
FAQ
What is the maximum profile length on your powder coating line?
Our horizontal electrostatic powder coating line processes aluminium profiles up to 7,000 mm (7 meters) in length.
Can you apply protective foil after powder coating?
Yes. Upon cooling, exposed decorative surfaces are laminated with UV-stable protective PE tape prior to bundling and crating.
What is your standard powder coating film thickness?
Our standard cured film thickness is 60–80 µm, verified per production lot with digital coating thickness gauges.
