4.Why the silicone mould turns to be sticky
The main reason for this problem is that we do not handle the products or original molds well.
We whould deal with the mother mould carefully before molding. Such as for the products with a complicated patterns or unsmoothed surface, we whould polish and clearn the products, then spray the release agent. Normally, the release agnet can be Vaseline, detergent, liquid wax etc. In practial process, you can brush different release agent according to different material.
The second reason is that the operator pour the silicone into the mold when the mixture is not mixed evernly, so the finished silicone mold will not cured and dried entirely.
