Although the utilization rate of PPGI coils is getting higher and higher, the quality requirements are also high, so how should we choose PPGI coils? PPGI coils manufacturers have sorted out the following related content:

       During the selection process of PPGI coils, the color steel gussets are first flicked with fingers. The metal sound of the color steel gussets with better materials is obvious and crisp, but the sound of the material is not obvious.

       During processing, an appropriate gap should be set according to factors such as mold shape, deformation characteristics, and process conditions, and the coating thickness should be considered. Most coatings can be used as solid lubricants to meet the lubrication requirements of most forming processes. Some coatings can be formulated to improve the lubricity of the coating. If the lubricity of the coating is insufficient, it can be improved by paint, wax and stripping the protective film.

       PPGI coils are not allowed to have obvious pores, air bubbles, accumulation and wrinkling, pitting, impurities, scratches, dirt, scratches, smudges and uneven coating. Severe paint leakage, coating peeling, color mixing and adhesion are not allowed. The coating is not allowed to become brittle, yellow and lose gloss due to over-baking, and it is not allowed to have obvious color difference or uneven gloss.

       The above is the correct way to choose PPGI coils. I hope you can refer to the above method in the future operation to avoid losses caused by blind operation.
