UK imported high quantity casting investment powder with strict quality standards control, factory passed S09001 equipped with advanced R&D testing facilities and professional engineers. All helps us to figure out the best solution during the process of new products design and audit. Different series are available for various requirement to make a smooth, perfect surface casting items, We have 50 pounds and 100 pounds package. As the increased requirement or palladium and platinum casting, we imported Japan A-l(min)casting investment powder. What’s more, considering the cost factor we developed Yihui Brand casting investment powder for palladium and platinum casting, which is more welcomed in domestic market.

Mixing rate:

1.Casting investment powder 1000g.  

2. Water 380-400ml (Water temp about 22℃).  

3. Pour water into mixing chamber, then add casting investment powder.  

4. Start mixing for 3.5~4mins.  

5. Inject mixed investment powder into flasks, then start vacuum 1.5~2mins.  

6. Take the flasks out, and wait 60~120mins before burning it .

Burn process:  

1. Put the flasks fulled with investment powder into oven, turn up the temp to 270℃ within 60mins, and keep at 270℃ with 180 mins.  

2. Rise temp evenly from 270℃ to 730℃ in 150 mins.  

3. Keep at 730℃ with 180mins.  

4. Start casting when the temp sum down to around 630℃.

Casting gypsum powder not only greatly expands the freedom of component design, improves the mechanical properties and air-tightness of the product, reduces the volume, but also greatly simplifies the processing procedures, saves a lot of equipment, and shortens the processing cycle. The cost is greatly reduced. Compared with the price of gypsum powder, the casting process is relatively simple, the production cycle is short, the equipment used is less and the price is not high, the technical level of the operator is not high, the labor intensity is low, the residual strength is low, and there is basically no pollution.
