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. FOQ of rtv silicone rubber for mold making: 1. Why does the silicone rubber mold have few molding times? 2.why is the tear strength of the silicone mold weak? 3.why is the silicon mold oily? 4.why isn't the silicon should acid& alkali and aging resistant? 5.why is the apprearance of the finished mold striate an unsmooth?
