640# Pouring Molding Silicone Rubber operation:
It is suitable for simple products with smooth surface and no any mold lines, which helps you save time and is easy for operation. Paint a layer of release agent on the product first, then make a square frame by 4 pieces of plastic or glass board to surround the product, the next step is to perfuse the mixed silicone rubber evenly and slowly into the square frame, after the cross linking reaction and the silicone rubber turns dry, you can take the products out, thus the mold has been done.
(Note: we usually use soft silicone rubber to make molds by perfusing, which is easy for demoulding and will not damage the product in the silicone molds.)
640# Pouring Molding Silicone Rubber FAQ:
Why is the silicone rubber mold oily?
Basically, molding silicone rubber doesn't contain any oil, so it won't be oily. The reasons for the oily molds can be deducted from the below 3 factors:
1. Added white oil, which is the compound of silicone oil and white oil. The white oil is not silicone oil but a kink of petrochemicals;
2. Added too much silicone oil. Normally, we donot advise our customers to add any silicone oil into silicone rubber. If necessary, the ratio must be 5%-10%;
3. Added too much curing agent, this is another reason for oily mold.
