These years silicone rubber products are gradually accepted by consumers, which for silicone rubber manufacturers, the production process has become an important factor for customers to choose silicone friends, if silicone products are not confirmed in the early stage of development, how to let customers accept it? Therefore, for the silicone rubber production process, the bad problems that will occur before the manufacture of silicone products, what do you need to know to take preventive measures?

First, the reason for the fog surface of silicone rubber products:

1. Molding vulcanization time is too short leading to immature fog surface;

2. The mixing temperature of the mixer is too high, the air is humid and the humidity is too large;

3. The mixing compound is not uniform for a long time, resulting in the vulcanization agent being completely dispersed;

4. The speed at which molding workers place raw materials can't keep up with the temperature of the machine, resulting in foggy surface of the product;

Second, the product defects caused by the forming machine:

1. Different thickness of raw materials leads to immature products, adjust mold pressure and increase temperature;

2. When silica gel products are manufactured, there is internal wind, maintain a certain time, maintain a uniform number of vulcanization, maintain a certain temperature of the mold, and you can use an air gun to blow the mold to dissipate heat;

3. The product appears outsourcing wind, the vulcanization time is extended, the temperature is raised, and the die pad is replaced;

4, frequently appear all kinds of bad, you can remove the mold, the mold pad on the machine template cardboard and silicone mold pad;

Third, mold caused by poor products:

1, mold sticky impurities caused by adverse phenomena, you can use kerosene to wipe the mold with cloth;

2, the mold is bruised, with different degrees of sandblasting machine to choose different sand for spraying;

3, silica gel mold sticking phenomenon, spray stripping water to keep the product normal stripping, long-term spraying will lead to mold fog surface, so normal spraying can be;

Four, the machine trapped gas problem:

Room temperature vulcanized silica gel trapped gas will cause a lot of confusion in production, mainly related to the mold, so the mold design should consider the problem of exhaust:

1. Exhaust frequency is not enough;

2. Room temperature vulcanized silica gel mold is unreasonable, and exhaust tank is added;

3. Secondary exhaust for appropriate products;

4. Spray a small amount of release agent.
