Operations of making molds by liquid silicone rubber
Step One: Take 100g of part A and add 2g of part 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 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 cross linking reaction, and no more further steps will be available.
Step Three: Brushing cast & Perfusion Molding operation
a. Evenly brush the mixed silicon rubber on the product which is covered with mold spray with a brush or a brush pen.
b. After the cross linking reaction (about 30 minutes), brush a second coat which can increase the tension and tear
strength of the mold.
c. Cover a glass cloth on it after another 30 minutes of a second cross linking reaction, and use a brush pen or a brush to avoid any interstices.
d. Cover a third coat.
(Note: if you have high requirements for the tension and the tear strength for the mold, please repeat step c and step d. Hence, the finished silicone molds will have a good quality and a longer life, which can help you save cost and increase production efficiency.)
It is suitable for simple products with the smooth surface.Without any mold lines,which helps you save time and is easy for operation.Evenly and slowly perfuse the mixed silicone rubber into the square from.After the cross linking reaction and the silicone rubber turns dry,you can take the products out.Thus,the mold has been done.
(Note:we usaully use soft silicone rubber to make molds by perfesion,which is easy for demolding and will not damage the product in the silicone molds.)
