ASAŞ producing aluminum strip in all shades and colors

At ASAŞ Alüminyum Sanayi ve Ticaret A.Ş. in Akyazi in the Turkish province of Sakarya, SMS group has established a color coating line for aluminum strip.  The line, including all mechanical, process-technological and thermal equipment as well as electrical and automation systems, has been completely supplied by SMS group.  

The line serves for providing the strip surfaces with a color coat consisting of several layers. Essential process components are cleaning section, tension leveler, vertical roll coater for passivation, two back-up roll coaters for color coating and finally two floatation ovens to dry the applied paints. The coating system comes with numerous options and fast changes in color. Furthermore, the line comprises equipment for hot and cold lamination and an embossing stand. The color coating section may be bypassed, if so required, and the line can be used either for tension leveling or for coating in the chem-coater. In addition to aluminum alloy strip, it is also possible to process steel strip with a small cross-section.

The materials made are largely applied in the construction industry, for example for façades, and to produce profiles or shutters. Further fields of application are the consumer electronics and household appliances industries.

Prior to the coating process, a tension leveler flattens the strip, and the surface is thoroughly cleaned. For this purpose, the line includes a pre-cleaning and a cleaning section, including alkaline and acidic spray cleaning zones each with subsequent cascade rinsing system.

Adhesion promoter and paint layer are both dried and hardened in a low-emission, contact-free floatation oven.

In the entry section, a stitcher mechanically joins the strips coming from two payoff reels in alternating order to an endless strip that is fed to the line.

For the color coating process, the line is equipped with several coaters. As a rule, the chem-coater initially applies a conversion layer, then the prime coater an adhesion promoter and finally one of the two finish coaters the paint layer.

In addition to a dividing shear and a tension reel, the exit section comprises a vertical inspection station, an embossing stand and a DUMA-BANDZINK oiling machine.

Solvent-containing exhaust gasses from the coating section are cleaned in an RTO (Regenerative Thermal Oxidizer), and the energy is returned to the system.

The line is also capable of applying special coatings such as woodgrain effects for the production of aluminum façades in wooden look.
