Resin arts mold making silicone rubber
Introduction of resin arts mold making silicone rubber:
Resin arts mold making silicone rubber is a kind of liquid fluid, features good fluidity and good operation., large duplication times
Features of resin arts mold making silicone rubber:
1. Good characteristics of easy-operation
2. Ligh viscosity and good flowability
3. Low shrinkage
4. Favorable tension
5. No deformation
6. High temperature resistance, acid and alkali-resistance and ageing resistance
Operations of resin arts mold making silicone rubber:
Step One: Take 100g of part A and add 2g of part B and mix the silicone rubber and curing agent evenly.
Step Two: Vacuum pumping
Without exception, this step takes less than 10 minutes. Otherwise, it will cause, and no more further steps will be available
Step Three: Perfusion Molding of gifts mold making of silicone rubber
The perfusion molding is an easy way to make molds, it's Slowly and evenly perfuse the mixed silicon rubber into the square frame. After the cross linking reaction.
Why is the appearance of the finished mold striate and unsmooth?
It is because the appearance of the product or the model itself is not perfect, and it has not been polished before the further operation. So when you make silicon molds, firstly you should Polish the product, spray the mold spray evenly on the product. In this case, the problem can be avoided.
