- Green color
BPA Free
C6H6 Free
Casting efficiently，95%success rate
We have tested it in different factories and the success rate can reach 95%.
it has been approved by the foundry craftsmen.
Working well with thin-walled parts
311C is more suitable for the thin-walled models. It can bring clear details and good casting results.
Easy to mold，Easy to print
lt can print various complex jewelry models.
The smallest jewelry model has a diameter of 0.15 mm, with little support and easy to detach.
Smoothing surface,
Casting ash residue <0.1%
The casting surface is smooth and does not show defects like sand pits. So the post-processing process will be much easier.
Low viscosity, Good fluidity
lt is easy to clean and provides high yiled after cleaning.

Casting gypsum powder
we had better choose the special embedding powder for casting resin.
Resin will expandand decompose at high temperature,while thespecial gypsum powder can work in a short time to ensure the strength of gypsum.
Casting resin burnout cyle
1. It takes 2 h for greenhouse to 200℃; 2 h from200℃ to 400℃.
2. Average heating from 400℃ to 750℃ takes 2 h.
3. Keep at 750℃ for 5 h.
4. Then drop back to about 630℃ and start castingProject Content Data value Testing method Physical and chemical properties
