Yixing Jiahui Building Materials Co., Ltd., primarily operates under the brand Jiawei, specializing in tile boards, thermal insulation boards, and production base for Yixing purple sand ceramic tiles, flat tiles, Spanish tiles, bamboo tube tiles, double tube tiles, S tiles, corrugated tiles, and various glazed tile accessories. Western-style glazed tiles are fired in a single firing process. After firing, they can be further processed in a coal-burning pusher kiln, which requires less investment, or in a tunnel kiln with an oxidizing flame. The components such as the hook head, drip tiles, animals, nail caps, lattice windows, and the front and hanging tiles are hand-shaped or cast using slurry molding. Hand shaping involves pounding clay into a泥饼, then pressing it into a patterned mold made of gypsum, allowing it to dry slightly before removing.
