The production method of hot stamping silicone plate

1. Open an aluminum mold, iron mold or copper mold, the kind that can be closed up and down, like a box, clean the mold first.

2. Apply a layer of mold release agent inside the entire mold (the mold release agent can be Vaseline or detergent) and wait for it to dry before proceeding with the following operations.

3. Fill the bottom of the mold with an aluminum plate (the top aluminum plate should preferably be punched with small holes to enhance the adhesion between the silica gel and the aluminum plate), put the aluminum plate in place, and clean the aluminum plate and apply adhesive to the aluminum plate. There can be multiple sheets of aluminum to fill, and the one on top is what really works. (The purpose of filling multiple aluminum plates is to adjust a thickness of the pressed silicone plate and put the bronzing silicone and the aluminum plate together)

4. Cut the silicone, the silicone plate is preferably 1 cm smaller than the aluminum plate, because during the pressing process, the silicone will extend around. Then slowly spread the silicone plate from one end to the aluminum plate, and then use a wooden stick to roll it from one end to the other on the silicone plate. The purpose of this is to catch the air. In this way, there will be no air and no air bubbles between the pressed silicone and the aluminum plate, and the bonding effect will be better.

5. Take the aluminum box to the pressing machine and press it.

6. Under the pressure of 10 tons and the temperature of 150-250, after 1 hour, pull out the mold, and after cooling, take out the hot stamping silicone plate.
