Aluminum panel roll coating process

Aluminum panel roll coating process

After degreasing and chemical treatment, the aluminum panel is roll‑coated with a high‑quality finish coat and then dried and cured. The surface film of roll‑coated panels exhibits superior smoothness compared to spray‑coated panels. Finishes are available in pearlescent and matte; pearlescent is the more common option on the market. Roll‑coating generally commands a higher price than spray coating. The standout feature of roll‑coated panels is their exceptionally realistic color reproduction, though the quality and grade of the roll‑coating process can vary significantly.

Methods for Using Aluminum Alloy Sheets

Grooving: When grooving with a grooving machine or router, use a semi‑round‑nose end mill with a cutting angle greater than 90°. The depth of cut should be neither too deep—risking damage to the aluminum panel—nor too shallow—making edge folding difficult. Leave a 0.2–0.3 mm thick plastic core layer, along with the aluminum panel, to bend the edge, thereby enhancing strength and toughness; otherwise, the aluminum panel may crack or the paint film may blister during bending.
