Features of Jewelry Casting Resin(311C)
It is an excellent resin material for 3D printing jewelry casting models.
Easy to Cast
After many tests by IFUN R&D department, a balance has been found between good casting results and 3D printing, which makes it easier for customers to cast directly.
Casting Efficiently
We have tested it with different factories and the casting success rate can reach 95%. 311C resin has been approved by the foundry craftsmen.
Precision & Smooth Surface
The success rate of 3D printing is up to 98%, and the surface is smooth and delicate with a small amount of grinding.

Rotary roaster oven are recommended. Ordinary roaster oven may underburn due to insufficient contact with oxygen. The rotary roasting machine can make the gypsum mold and oxygen fully contact, greatly improving the success rate of casting.
1.Greenhouse to 200 ℃ must be 2 hours
2.2 hours from 200°C to 400°C
3.Average temperature 400℃ to 750℃ for 2 hours
4.750 ℃ for 3-5 hours (time depends on the specific version of the model)
5.The temperature drops back to about 630℃ and starts to cast
