Embossed Coated Aluminium Sheet

Embossed coated aluminium sheet are mainly used in the decoration of household electrical appliances, such as refrigerator door side panels, water heater shells, TV back panels, washing machine panels, etc. A variety of stucco embossed patterns are used to increase the aesthetics of the appearance of home appliances.

At present, the embossed color coated aluminium sheet mainly uses the embossing roller to emboss the surface of the coated aluminium sheet substrate to obtain the required embossing effect, so as to avoid the embossing process from damaging the metal substrate and ensure the overall performance of the embossed color coated aluminum sheet.

During the embossing process of the embossed coated aluminium sheet, a paint layer is first placed on the surface of the coated aluminium sheet substrate, and the paint layer is cured and softened by baking, and then cooled to keep the paint layer in a semi-softened or fully softened state, and then an embossing roller is used on the paint layer. The embossing pattern required for surface embossing. During the embossing process, the paint layer is in a fully softened or semi-softened state, which reduces the pressure required for embossing. At the same time, the embossing roller only acts on the surface of the paint layer, avoiding the embossing process. The influence on the metal substrate ensures the overall performance of the embossed color coated aluminum sheet.

During the production of embossed coated aluminium sheet, the embossing roller is provided with the same pattern as the embossing pattern, and the pattern includes several sub-patterns, and the several sub-patterns are evenly arranged along the circumferential and axial directions of the embossing roller, so that the embossed pattern is uniform. , has good integrity, preferably, the pattern pattern is a continuous pattern formed by radial expansion of the embossing roll, and the number of sub-patterns in the transverse and longitudinal directions is an integer multiple of a single sub-pattern. Preferably, the depth of the embossed pattern is 0.1-0.3 mm, and after embossing, an embossing pattern with an upward protrusion of 0.005-0.045 mm will be formed on the surface of the coating layer.
