First of all, we want to understand the main performance of silicone difficult demoulding?
The performance is: in the production of products, the finished product and the mold are tightly adsorbed and difficult to be separated, resulting in low efficiency or poor product rupture
The main reasons for this problem are as follows:
1. The structure of the product is complex and there are many holes;
2. The inlaid product and the use of vapor phase adhesive are easy to produce adsorption;
3. The thick material is too sticky and the plasticity is low
The solutions are as follows: 1. Spray mold release agent before use, and keep the mold under high temperature for 20-30 minutes
2. The surface of mould is plated with Teflon
3. The mold surface is sprayed with external release agent at regular intervals
4. Adjust the formula of raw materials to make it dry
5. Regularly clean the mold and sandblast
