First, the quality of silicone raw materials is not good, performance is poor, toughness is not good, then it will easily lead to the situation of rupture,
Therefore, the raw material of silicone must be good;
Second, silicone products in the vulcanization process is not complete, when the mold temperature is too low or curing time is too short, it will cause
The product is tightly attached to the mold and is not easily demoulded. It is also prone to cracking and may also appear.
In other conditions, it is necessary to increase the molding temperature or increase the curing time in the curing process.
Third, the temperature of the silicone product molding is too high, the temperature is too high will make the silicone products become brittle during molding, easy to take off
When the mold breaks, it is prone to cracking, so reduce the molding temperature appropriately;
Fourth, the surface of silicone mold molding mold is too rough or accumulation of dirt, it is not conducive to demoulding, it will also cause the rupture, only need to clear the mold or plating!
Fifth, the operator's operation method for demoulding is not regular, it will be more prone to many problems, broken silicone products
The situation of cracking is inevitable.
However, we can reduce the proportion of defective products caused by cracking because of our good specifications. Generally, silicone rubber products in broken silicone products account for the majority, so we must pay attention to these aspects in the production process.
We are a factory with 18 years of experience. Our technology is mature. We have a professional after-sales team.
