The reasons and solutions for the pits/concave-convex shapes on the surface of silicone products are as follows (for reference only):

　　1. First check whether the mold is abnormal: whether the mold is flat and clean. If the mold is not clean or the mold is not flat when the mold is opened, it will cause the product to appear in this state during production.

　　2. Check whether the vulcanizing agent is excessive and whether the storage time is too long after the raw materials are mixed.

　　3. Lack of material and less material, you can add rubber material appropriately.

　　4. Check whether the mold temperature is too high: if the temperature is too high, lower the appropriate temperature.

　　5. Check whether there are too many exhaust times and whether the exhaust stroke is too large;

　　6. The discharging speed of the operator is too slow, the thickness of the raw material is too thin, and the pressurizing speed of the machine is too slow.
