Pouring Mold Making Silicone Rubber Features:
620# pouring mold silicone rubber, with hardness of 18-22 shore A, is particulary suitable for mold making for small-sized crafts with complicated designs;
640# pouring mold silicone rubber, with hardness of 38-42 shore A,is applicable to making molds for large crafts with simple designs, especially the products larger than 100cm.
Pouring Mold Making Silicone Rubber Advantages:
Light viscosity;
Pourable effort;
Good fluidity;
Easy-operation;
Good tensile and high tear strength;
High reproduction times;
Resistance of high temperature.
How to Make Silicone Molds in Pouring Way?
RTV-2 molding silicone rubber contains two parts: part A is liquid silicone rubber, part B is curing agent.
1. Prepare the original molds: You must make sure the original molds is perfect and fix it on a board, stick the board with mold to another board, and make a frame with four pieces to enclose the molds;
2. Clean the original mold with soap water, and dry it, then evenly brush a lay of mold release agent;
3. Mix both A and B parts totally by weight at the ratio of 100:2-5 (A to B)in a clean container(weight of part B is always depending on your local temperature. Basically, we advise you add 5%part B at the room temperature 25C; if the temperature is more than 30C, we advise you add less part B; if temperature lower than 15C, we advise you add more part B). Making sure that A and B mixed evenly, otherwise the compound will be partly solidified and this will give birth to difficulties in the following operations, leading to the short life of your final molds.
4. Degas the compound by a vacuum pump about 3-5 minutes(usually no more than 10 minutes), otherwise, it will cause cross linking reaction, and no more further operations will be available.
5. Pour the mixed and degased silicone rubber into the frame slowly and evenly. 30-45 minutes later, you can demould the mold and use a knife to remove the surplus silicone in the edges.
6. Take it into mass production after 24 hours.
