Anodizing Practice

The operations required for the anodic oxidation of aluminum and its alloys with subsequent sealing or dyeing of the film are outlined below:

1. Anodizing with Subsequent Sealing of the Film

a. Degrease with organic solvents

b. Dry

c. Jig Parts

d. Clean unpolished parts chemically and polished parts cathodically

e. Wash in hot running water

f. Wash in cold running water

g. Remove smudge

h. Wash in cooled running water

i. Inspect

j. Dye

k. Wash in cold running water

l. Wash in hot running water

m. Remove from jigs

n. Dry

2. Anodizing with Subsequent Dyeing of the Film

a. Degrease with organic solvents

b. Dry

c. Jig Parts

d. Degrease unpolished parts chemically and polished parts cathodically

e. Wash in hot running water

f. Wash in cold running water

g. Remove smudge

h. Rinse

i. Anodize

j. Wash in cold running water

k. Inspect

l. Dye

m. Wash in cold running water

n. Wash in hot running water

o. Remove from jigs

p. Dry

In anodizing process part 1 usually use for aluminum parts that is used for other parts or for spare of other thing. In anodizing process part 2 is used for part that use for finished material like key handle, window frame etc. Each of those process will describe more detail in further.
