The process of manufacturing powder coatings is a relatively complex process that must be carefully controlled to ensure a high-quality final product. Powder coatings are manufactured in a multi-step process of pre-mixing, extrusion, and micronization. Basically, materials are blended, melted, cooled, and then pulverized. This blog will focus on micronizing, the last step in the process.
Micronizing Process: the powder chips are fed into a grinding machine, which breaks the chips down into a fine powder. The powder is then filtered to ensure that no large particles contaminate the powder.
