Plaster for porcelain
>Wet press/special casting

??

Clogging and subsequent reduction in water absorption are prevented by introducing air to wash away particles that have entered the plaster mold during casting.
To dry a plaster mold, air is introduced into the mold to discharge the water inside. This allows the water content to be adjusted to a quantity suitable for casting (10 - 15%) in a short time. This eliminates the necessity for using a heat source to dry a mold.


>HI-SUCT Series

??

“HI-SUCT” shows a high water absorption characteristic even with a low amount of mixing water. This results in good releasing from the green body, improving the efficiency of the molding. In addition, rapid diffusion of water in the mold shortens the drying time. In this way, this product has many advantages. Five types are available to cover various applications.

>High Expansion Type

This product is a special type of plaster exhibiting an ultimate expansion coefficient of about 7%. The main application of this product is the compensation for a 13%-or-so shrinkage allowance of a porcelain green bodies, for which this product has been developed. It allows the shrinkage allowance to be compensated for by carrying out inversion twice from the mother die.




For models of dies and molds
>PEARL STONE B-10,B-11

??

This product is made by mixing water-soluble resin powder into high-strength · -hemihydrate gypsum, offering the advantage of being superior especially in strength and hardness to other types of model-use plaster. Making the most of the features of this product to suit your specific purpose and application enables high-precision, solid, and ultra-hard models to be fabricated fast and economically.


>Low expansion plaster for models B-13 Series

??

The B-13 plaster is a typical kind of plaster used most extensively among low expansion types of plaster, having great hardness and strength accompanied by a low expansion coefficient. Several kinds of B-13 Series plaster are available to suit different applications. Selecting one that suits a specific working method enables a high precision model to be created economically.


>High expansion plaster B-14L

??

The B-14L Series plaster exhibits large setting expansion (about 0.5% to 2.0%) unseen in conventional casting plaster, which is obtained by treating high-strength casting plaster with a special method. It is used to make expansion models and expansion molds requiring a compensation for setting shrinkage of metal or synthetic resin.
