Other Industrial Plaster(Metal Casting Plaster)
● Characterize
- This product is made of light steel gypsum for a high precision level based on pressurization and de-pressurization. It has the following characterize.
It can reproduce detailed shapes.
1. The casting (Metal Casting Plaster) results in highly smooth surfaces.
2. It result in highly accurate models.
3. It can cast very thin casting products.
● Uses
- Various types of plastic steel castings (aluminum or zinc alloy, etc.)
- Various types of steel press castings (zinc alloy)
- Other highly – accurate non-steel castings.
● Kind of Products
Type | Water consistency | Mixing time (min.) | Mixing time (min.) | Expansion rate | Dry compressive | Dry shrink ratio |
|---|---|---|---|---|---|---|
C-1000 | 40 | 5~7 | 50 | 0.2 | 45 | 0.2 |
● Choosing a Casting Method
- White casting with gypsum models produces good surface quality and precision, air ventilation is poor, thus requiring a pressurized or de-pressurized casting facility.
1. Pressurization Method
Please apply pressure of about 0.3~0.7kg/cm² to a cast to get a high-quality surface.
2.Depressurization Method
The depressurization level should be between 20 and 30cmHg, usually for about two to three minutes.
