The document summarizes the process of manufacturing porcelain tiles. It involves several steps: material selection and preparation, pressing, drying, printing, ball milling, baking, polishing, grading, waxing, packaging, and warehousing. The process is divided into two main parts - producing the tile bodies and further deep processing. Deep processing involves burnishing, grinding, polishing, pure bright treatment, and quality checking to produce high quality finished tiles. The fully automated production line and multiple quality checks help ensure consistent quality in the final products.
