Frequently Asked Questions

Q: What are the common surface treatment processes for metal enclosures？

Common processes include: painting (suitable for outdoor equipment enclosures), galvanizing (suitable for industrial enclosures with high rust resistance requirements), anodizing (suitable for aluminum enclosures), and brushing/polishing (suitable for scenarios with high appearance requirements).

Q: Can surface treatment solve the corrosion problem of metal enclosures？

We can customize surface treatment solutions according to the specific environmental needs of the product's use.

Q: Can the color after surface treatment match the sample？

Through standardized color number control (such as Pantone color cards, RAL color cards), the color difference for small batches is ΔE≤1.5;

for mass production, automated spraying lines are used, and the color difference is controlled within ΔE≤2.0.

Q: Will the coating after surface treatment peel off？

Strict surface pretreatment (degreasing, derusting, phosphating) will be carried out before treatment to ensure coating adhesion.

Q: Will the thickness of surface treatment affect the assembly accuracy of metal enclosures?

The coating thickness can be adjusted between 5μm and 100μm according to the process. In addition, coating thickness tolerance will be reserved for assembly parts; for example, the gap between the door panel and the frame of the control cabinet enclosure can be maintained at 0.2mm±0.03mm.
