Operation Instructions
 

Step 1: Prepare the original moldsPrepare a perfect original mold and clean it well before your operation.

* Make sure your original molds and operation tool cleaned up totally to avoid uncured problem.

 

Step 2: Scale 100g of Part A and 100 g of Part B and mix them evenly.

Platinum cure mold making silicon rubber is Two-Parts flowing fluid, please follow the step below strictly:

 

1.  Weigh the two parts exactly by electronic weight. 

(If any part not in exactly weight, it may cause changing of hardness, or even cause uncure problem).
 

2.  Mix part A and part B evenly.
(Otherwise the silicon rubber will be partly solidified and this will cause difficulties in your final operation.What's more,the finished molds will meet a short life. All of these will cause a waste of silicon rubber).

 

Step 3: Vacuum pumping.

Without exception, this step takes less than 5 minutes. Otherwise, it will cause cross linking reaction, and no more further steps will be available.

 

 

Step 4: Pouring casting.

1.  For simple pattern products we suggest to use pouring operation way, which will be very easy to do and demould. Pourable silicone require light viscosity which will be easy to flow smoothly and easy to de-air.

 

2.  We suggest to set the silicone mold for another 12 hours after demould before duplicating .

 

 

 

Warm tips:

As platinum cure silicone is a kind of platinum cure system ,which will be easy to cause uncure problem .

 

Hence kindly follow the tips below :

Do not mix with liquid tin/condensation silicone rubber or even the tools which are already used for tin/condensation silicone.

Do not mix with organic matter which contains N, S, P organics and ionic compound like Sn, As,Hg, Ph.

Do not add any pigment or powder into the platinum/addition cure silicone rubber without any testing to prevent uncure problem.
