Using instructions
Step 1: prepare the original molds
You must make sure your original molds perfect. fix it on a board. And fix the original mold on a board , then used four piece of board to enclose the original molds .
Step 2: Take 100 parts A and add 3 parts B and mix the silicone rubber and curing agent evenly.
*Notes: Molding silicon rubber is a kind of flowing liquid and it contains two parts. Part A is a kind of 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 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 10 minutes. Otherwise, it will cause , and no more further steps will be available.
Step 4: Pouring cast or brushing cast
*Notes: We usaully use soft silicone rubber to make molds by pouring molding, which is easy for demoulding and will not damage the product in the silicone molds.)
