Precoated Aluminium Sheet

The production of precoated aluminium sheet is to uniformly coat a certain thickness of coating on the surface of the pre-treated aluminum by a precision roller coating machine, and then enter the baking oven with a scheduling device at a uniform speed for baking and curing. The process of obtaining a complete roller coating film with a certain thickness.

Roller coating uses the coating roller as the carrier of the coating. The coating forms a wet film of a certain thickness on the surface of the coating roller. The coating roller is used to contact the object to be coated during the rotation process, and the coating is applied to the surface of the aluminum sheet coil.

Characteristics of pre coated aluminum sheet:

Roller coating is suitable for the coating of flat metal plates, especially for high-speed coating of pre painted aluminum sheet. Roller coating requires that the coating has good leveling, wettability and adhesion, certain hardness, flexibility and wear resistance, good weather resistance and stain resistance, and the coating is baked and cured quickly to form a film.

Features of pre coated aluminum sheet:

1, High-speed automatic coating operation, fast coating speed, high production efficiency, the line speed is generally above 60m/min, and the highest line speed can reach 244m/min.

2, Except for some remaining paint on the paint tray, the paint utilization rate is close to 100%, and no paint mist is generated during the production process, which is relatively more environmentally friendly and safe.

3, The thickness of the coating film can be controlled by the fixed film roller to keep the thickness of the coating uniform.

4, It can be painted on both sides at the same time.
