Operation Instructions
Step 1: prepare the original molds
Prepare an perfect original mold and clean it totally before operation.
Notes: Make sure your original molds and operation tool were cleaned up totally to avoid uncured problem .
Step 2: Take 100 G part A and 100 G part B and mix them evenly.
Notes: Addition cure mold making silicon rubber is two parts flowing liquid, Pls follow the step strictly:
1.Weigh the two part exactly by electronic weight. If any part not in exactly weight, it may cause changing of hardness, or even cause uncured problem.
2.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 molds will meet a short life. All of these will cause a waste of silicon e r ubber.
Step 3: Pouring casting operation
Notes:1. we suggest use pouring operation way, which will be very easy to operate and demould. Pourable silicone require low 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 you put it into a large production .
