The reasons are as follows: First, in order to develop the market for artificial marble, especially the construction market, manufacturers actively develop their uses, develop a wide variety of products, and make products with high added value; From the point of view of technological development, the manufacturing technology of artificial marble has progressed from the traditional casting without reinforcement to the DMC molding with glass fiber reinforcement.
