[0003] In order to meet the aesthetic needs, the shape of glass handicrafts is unique. The traditional glass handicraft production process is to use sand molds for modeling. Although sand molds have the advantages of high refractoriness, low cost, and simple mold making, due to the high requirements of glass handicrafts, glass After the handicraft is formed, its surface needs to be very smooth, and for mass production, it is also necessary to make requirements for the reusability of the mold, but the sand mold cannot meet the needs well in this respect, and is only suitable for the production of small batches and relatively rough finished products. Glass handicrafts can no longer meet the needs of manufacturers and users
