For General-use: HS-600

The HS series features high water absorbency despite its low water-mixing amount and offers superior removal from new molds and improved forming efficiency. This plaster offers many advantages, such as shorter drying times due to quick diffusion of moisture within the mold.

Areas of use
General lathes and more

Packaging
25kg

For General-use: HS-650 (High grade equivalent)

The HS series features high water absorbency despite its low water-mixing amount and offers superior removal from new molds and improved forming efficiency. This plaster offers many advantages, such as shorter drying times due to quick diffusion of moisture within the mold.

Areas of use
General lathes, pressure casting, and more

Packaging
1kg, 20kg, 25kg

For General-use: HS-700

The HS series features high water absorbency despite its low water-mixing amount and offers superior removal from new molds and improved forming efficiency. This plaster offers many advantages, such as shorter drying times due to quick diffusion of moisture within the mold.

Areas of use
Pressure casting and more

Packaging

For Sand Match Prototype Molds: HS-700 Low-Expansion

The HS series features high water absorbency despite its low water-mixing amount and offers superior removal from new molds and improved forming efficiency. This plaster offers many advantages, such as shorter drying times due to quick diffusion of moisture within the mold.

Areas of use
Sample molds and more

Packaging

For Cases: HI-Case

HI-Case is the number-one, most widely used plaster for cases. High-accuracy case molds enable economical manufacturing.

Areas of use
Case molds and more (mainly lathe molds)

Packaging
25kg

For Cases: H23B

With its long working time and excellent cutting workability, this plaster is ideal for making cases for large-scale casting.

Areas of use
Case molds and more

Packaging
25kg

For Cases: ST-Case

With its minimal expansion and excellent dimensional precision, this plaster is ideal for large-scale case mold manufacturing.

Areas of use
Case molds and more

Packaging
20kg

For Wet Presses and Special Casting: C-100P

This plaster is ideal for pressure-forming using tile and special ceramic presses.

Areas of use
Simple presses, wet presses, high-pressure casting, and more

Packaging
25kg

For Special Casting: C-100

>Clogging and moisture precipitation of fine particulates in plaster molds during casting can be prevented through air injection and washing. While the plaster mold is drying, air is injected and water is poured inside it, enabling the regulation of moisture levels (10–15%) ideal for quick casting. Because of this, cast drying using a heat source is unnecessary.
