Ceaseless challenge toward the top
Gypsum for making pottery
As premium gypsum for specialist which is necessary to the ceramic ware and hygienic pottery, it is a high performance product for making a variety of products from general purpose to case molds. As gypsum for high performance pottery which is developed for heightening efficiency of large scale production and precision from ware, quality of product and the degree of completion and precision, MUNGYo insists on the highest quality raw materials and has extremely high standards to create quality HICAST products.
Hi CAST is a worldwide product beloved by many people for its excellent workability that enables precise work and reduction or production cost.
This high quality ceramic is perfect for precision work because it contains exceptional fluidity and superb flexibility and is extremely hard and has low expansion. This type of ceramic is excellent for mass production of CASE MOLD.

There are two kinds: one in which one manual pours the plaster and the second which is using the pressure of a machine to pour the plaster. Both of them are used frequently to quickly mass produce complex types of ceramics, such as sanitary ware, teacups and bottles. The plaster sets uniformly allowing high flexibility and a low change of bubbles forming.
