Applications of silicon rubber for molds:
Silicone rubber is mainly applicable to manual mold design, PVC plastic molds, cement product molds, melting point alloy molds, alloy toy craftworks, plastic toy craftworks, gifts and stationery, large statues, duplication of cultural relics, shoe sole mold fabrication, pad printing positioning, shock resistance for electronic equipments, etc

Features of silicone rubber for molds:
1. Good characteristics of easy-operation
2. Ligh viscosity and good flowability
3. Low shrinkage
4. Favorable tension
5. No deformation
6. Favorable hardness
7. High temperature resistance, acid and alkali-resistance and ageing resistance

Operations of silicone rubber for molds:
Step One: Take 100g of part A and add 2g of part B and mix the silicone rubber and curing agent evenly.
Notes: Moulding silicon rubber is a kind of flowing liquid and it contains two parts. Part A is a kind of white flowing liquid and part B is the curing agent. Remember to mix part A and part B evenly, otherwise the silicon rubber will be partly solidified and this will give birth to difficulties in your final operation. What’ s more, the finished moulds will meet a short life. All of these will cause a waste of silicon rubber.
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 Two: vacuum pumping

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 isn’ t the silicon mold acid & alkali and aging resistant?
It is due to the addition of the silicon oil. Normally we do not advise our customers to add any silicon oil into the silicon rubber. If it is necessary, the ratio must be 5% -10% .
