What’s the operation procedures for making Pouring or perfusion mold?

pouring or perfusion mold is always used for simple or smooth products, but it will cost more time and labour than mold line. Enclose the products with plastic plate or glass plate, pour the vacuumized silicone onto the products, after the silicone cured, you can take out your products, then a mold is formed.(note: Generally, in this pouring way, you should use low-hardness silicone rubber to make molds, so it will be easier to demould and will not destroy the products.)
