Silicone products have a very wide range of applications and powerful functions, and are very good products. In the production process of silicone products, a very important part is demoulding.silicone compression molding What if the silicone products are not easy to demould?
1. Surface treatment of the mold 1) The molding mold of silicone products should be cleaned before the hydraulic molding machine, especially the new mold that has just been removed must be sandblasted first. 2) Use different detergents for mold. 3) The sandblasted mold must be heated to a sufficient temperature before mold release, and the release agent must be sprayed well before molding.
2. Adjustment of mold temperature Silicone products like to stick to the lower half of the mold temperature. When the upper mold temperature is 175°C and the lower mold temperature is 165°C, the product usually sticks to the lower mold when the mold is lifted.
If the above method is not very effective, you can consider adding an appropriate amount of internal mold release agent when formulating the material, but it will increase the extra cost of the product.
