How can rubber and mould not be bonded when producing rubber products?
Rubber is soft nature of the product, the draft (draft angle) is not to die. In other words, theoretical deduction is possible. However, the complex structure, a little larger, and often die adhesion is difficult to remove, and part of the solution can be solved with release agent.
When rubber products are made, rubber and mould can not be bonded:1, abrasives to be polished, coating treatment, to achieve the most smooth surface and high temperature corrosion resistance requirements!2, formula design, less use of sticky, easy to corrosive materials;3, curing process should meet the requirements of formula design!
Mold release can not be solved, we can only start with the mold structure. Because the main reason for adhesion is the complex structure of the product, resulting in strong vacuum adsorption between the mold and the mold. In view of this, we can do a few more exhaust at the appropriate location of the mold. If allowed, you can also modify the product structure, of course, this is unlikely. But really can not do it, this is the best solution.
