, high-temperature, acid and alkali and expansion, comfortable duplication times and free sample avalibale. Molding silicone rubber operations: mould silicone rubber is a kind of flowing liquid, and it consists of two component, part A is aflowable liquid silicone rubber, part B is the curing agent. Firstly, after your previous work of dealing with the origianal moldel, take some liquid silicone rubber, add 2%~3% cuing agent of the amount of silicon and mix them evenly. Then after vacuum-pumping the mixture, you cn pour it into the mold frame. The sillicone mold will cured in 2~3 hours. Note: the time for vacuum-pumping should be less than 3-5mins, othewise, once the silicone rubber has cross-link reaction during vacuumizing. it will not be operated.
