COIL ANODIZING
The Beauty Is In The Process.
CONTINUOUS COIL ANODIZING
Lorin Industries specializes in coil anodizing as the most useful method for its clients due to the utility, consistency, and affordability it brings. Coil Anodizing is an electrochemical process where we grow the anodic layer from the base aluminum, not an applied coating. Coiled raw aluminum is unwound and pulled through a series of tanks, each playing a vital role where we clean, anodize, color, seal, then rewind the coil all in one continuous process. The end result is a technical wonder that provides many benefits including: Cost and Production Efficiencies, Beauty and Versatility, and Sustainability and the Environment.

THE COIL ANODIZING PROCESS
ALUMINUM COIL ANODIZING LINE
EXPLORE EACH PHASE
From pre-treatment to anodizing to post-treatment, each phase of the Coil Anodizing Process strengthens aluminum into an amazingly durable, versatile and superior building material.
Discover the superior functional performance of each phase below.
PRE – TREATMENT
CLEANING – Cleaners are used on the raw aluminum to dissolve any contaminants.
BRIGHTENING & ETCHING – Chemical brightening smoothes surface roughness, and a chemical etching process removes any imperfections and controls the aluminum surface finish.
ANODIZING
After pre-treatment, an anodic film is built from the aluminum itself. An electrical current is passed through an electrolyte bath in which the aluminum has been immersed. The anodic thickness can be tightly controlled and is hard and porous for accepting coloring dyes.
POST – TREATMENT
COLORING – Methods such as Absorptive Dye Coloring and Electrolytic Two-Step Coloring provide endless possibilities.
SEALING – Pores in the anodic film are closed, locking in colors, and creating a surface resistant to staining, abrasion, and color degradation.
COIL ANODIZING vs.
BATCH ANODIZING
COIL ANODIZING – process is tightly controlled creating a uniform anodic layer resulting in a very consistent surface appearance and elegant colors.
COIL ANODIZING – coils are placed at the start of the process and remain unhandled until the end of the process, resulting in less scrap and lower costs.
BATCH ANODIZING – an electrical contact must be made on each part which causes a rack mark. Trimming rack marks will increase scrap and overall processing costs.
