Mold Plasters for Ceramic Industry
Though engineers have been working on complicated and expensive production techniques of ceramics, plaster still has a very important place in the majority of manufacturing techniques for ceramic products.
Ranging from the production of sanitaryware to tableware products, we manufacture a complete line of plasters for the ceramic and porcelain industry that are used to shape products via molds with every kind of technique.
The plaster's initial set, vicat ring spread diameter, capillary volume, expansion and strength can depend on the shape of the case you mix the plaster and water in, the temperature of the water and the pace you mix it. It can also depend on the environment's temperature, the total mixing time and the technique in which it is mixed.
