Operations of RTV silicone rubber for mold making
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.
Notice of RTV silicone rubber for mold making
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?
The silicone rubber mold has few molding times is due to follwoing reasons: Adding too much silicone oil which will destroy the molecular of silicone rubber; Making the mold for small and fine detailed products with higher hardness silicone rubber which is easy to break; Making the mold for large products with soft silicone rubber which will reduce the tensile and tear strength of the mold, and the mold will have deformation. Thus, we should take the proper silicone rubber to make the mold for suitable products.
