Frequently Asked Questions
What are the main advantages over spray coating?
Superior finish quality, higher material efficiency, and no overspray contamination. It is the best choice for high-gloss, flat surfaces.
Can it coat 3D shaped products?
It is best suited for flat or mildly curved products. The vacuum conveyor bed can be customized to hold specific 3D shapes, but steep angles may cause curtain disruption.
