Rough/wrinkled casting surface: 5 major causes+precise solutionsIn precision casting production, the surface quality of castings directly determines the appearance accuracy, density, and service life of products, and surface roughness and wrinkling are one of the most frequent surface defects. These types of defects not only affect aesthetics, but also increase the difficulty of subsequent processing, reduce coating adhesion, and in severe cases weaken the strength and corrosion resistance of castings, resulting in···...
