What is the reason for the uneven surface of silicone products?

Latest company news about What is the reason for the uneven surface of silicone products?

More and more silicone products are becoming popular in the market, inevitably with advantages and disadvantages. After using some silicone products for a period of time, the surface may not be smooth enough and there may be a sticky feeling, especially in kitchen utensils or silicone phone cases. What is the reason for the uneven surface of silicone products?
1. Caused by raw material issues or improper maintenance.
2. It is unreasonable to control and use curing agents during the mixing process of raw materials. The amount of curing agent added is not fully cured, resulting in a sticky surface of the product.
3. During the kneading process, the curing agent and silicone gel are unevenly stirred, and the mold solidifies while curing, causing deformation of the product due to differences in hardness and hardness after vulcanization.
4. When cleaning the machine, if the mold is not cleaned, it will not be smooth enough. The residue in the mold can cause unevenness in the product, resulting in an uneven surface and insufficient treatment, such as the absence of secondary vulcanization and spray paint.
In short, the production of silicone products should pay attention to every detail to avoid unnecessary cost waste.
