Other early methods to produce powder coatings were two-roll mills, and Sigma mixers for melt mixing. Product output was low for both types of equipment, and Sigma mixers needed extensive cleanup after each batch. Extrusion methods for producing thermosetting powder coatings were further developed by Shell from 1962 to 1964.

AAMA 611 is a new anodizing specification which has limits established for color variation. It is hoped that AAMA 611 will become an industry standard. The closest thing to a standard for painted and powder coatings is AAMA 605 which has a clause that recommends viewing finished products from a distance of ten feet.

Aluminum parts are brushed with, sprayed with, or dipped into the conversion coating solution to form a yellowish or golden brown film with a thickness of 0.00001–0.00004 inches. The conversion coating process is very quick taking only 1 to 5 minutes. The excess chromate solution is wiped off and parts rinsed.
