Introduction to silicon raw material :
Silicon raw material is a kind of liquid fluid, features good fluidity and good operation., large duplication times
Features of silicon raw material:
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 silicon raw material:
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
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 should the silicon raw material mold be reused only for a few times?
It can be due to the following reasons:
a. Adding too much silicone oil in to silicon rubber. Silicon oil is an additive which destroies the molecular weight of silicone rubber and reduce the tension and tear strength.
b. Using the silicon rubber with a high hardness to make molds for small sized products with delicate and intricate designs and the silicon rubber with a low hardness to makes molds for large sized products with simple designs.
(Notes: we should choose the silicon rubber specifically according to the requirements of our products to avoid this problem.)
