Silica gel is bad cause demoulding. What should I do?
Silica gel products factory talk about with you
For some silicone manufacturers in the production of silicone products, silicone products molding mold release, more or less will encounter molding difficult demoulding problem, this will directly influence the silicone products of the production efficiency, so face the problem of difficult demoulding, how should solve?
By silica gel products factory to following several small confession to you reference.
A: mold surface treatment of silica gel products molding tooling in the hydraulic molding machine in front of processing, especially had just put the electricity new sandblasting processing mould must first;
Cavities for choose different mould sand washing.
Just finish spray sand mould must be heated to a temperature enough discharge again after forming, and must be good spraying mold release before molding.
It is worth noting that the electroplating mold must not sandblasting, including spray resin sand.
2: injection mold release agent processing molding silicone products, silicone products don't adhere to any side mould surface spray mold release agents, but sometimes is not easy to stick.
Solution: use a spray bottle or other with clean water, hope the product spray adhesive which is where, after the injection and molding, products will obediently stuck to want to put them.
3: the adjustment of the die temperature products like to half of the mould temperature low viscosity, when the upper die temperature 175 ℃, the mould temperature 165 ℃, the product when lift mode is often stuck in mold.
You can adjust according to the appropriate here.
After solved the problem of the molding difficult demoulding, for the silicone products of the production efficiency will be greatly improved.
