The column washbasin mold is made of high-strength FRP (fiberglass reinforced plastic), specifically designed for concrete and artificial stone casting. The high-gloss finish facilitates easy demolding. The FRP incorporates a substantial fiber-reinforced structure, providing excellent rigidity and resistance to warping, with a service life exceeding 700 uses. The mold consists of 3 or 4 interlocking pieces and features a pouring port at the top for simple operation.
