The technology research and development center has complete inspection equipment and facilities, as well as a comprehensive inspection system and detailed rules. From raw materials to finished products, we start from the fineness of the powder, specific surface area, loose density, moisture content of the powder, density of zirconia beads after porcelain formation, roundness strength, internal structure of crystals, self abrasion of spheres, and other measures. We steadily develop and continuously research and develop new products to meet the needs of market development.

During the grinding process, the wear of zirconium beads varies depending on the material used. In response to this phenomenon and considering the actual situation of the customer, we have also launched a series of products to meet their needs. We hereby solemnly promise that if any zirconium beads are damaged, broken, or worn during normal operation of our company's products (excluding mechanical and human factors), the company will replace them free of charge. We provide free screening screens and after-sales personnel to provide screening technical guidance every six months.
