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···...

In the process of jewelry casting, flash and burrs attached to parting surfaces or hole edges are like rough "excrescences" that compromise the dimensional accuracy and surface quality of castings. These excess thin metal residues on casting edges are invisible profit drains—they not only lead to high rework costs but also cause mass production issues or even batch scrapping, becoming a fatal blow to customer trust. As a craftsmanship-focused factory with over 20 years of experience in precision jewelry ···...
