Precautions for quality requirements during the production process of silicone buttons

- Feb 15, 2019-

The biggest quality requirement of the silicone button is not broken. There will be a certain probability of rupture in the daily application. There are many reasons for this. Generally, the silicone button manufacturers are mostly in the miscellaneous pieces of silicone rubber. Of course, the silicone button There may also be poor rupture during production. In addition, the silicone button is also called: silicone button, silicone button, silicone button, silicone rubber button, silicone button. There are six main reasons for rupture:

First, the temperature is too high during molding

When the temperature of the silicone button is too high, it will become brittle. After the molding, the mold is released, and it is easy to be broken. It is only necessary to appropriately lower the molding temperature.

Second, the silicone button vulcanization is not complete

When the temperature of the silicone button molding mold is too low or the curing time is too short, the product will not be easily released from the mold, so it is easy to cause cracking, and the mold temperature can be appropriately increased or the curing time can be extended.

Third, the surface of the silicone button molding mold is too rough or accumulates dirt

A cavity having a rough surface or accumulating dirt is unfavorable for demolding, and a mold that is not easily demolded is easily broken, and the mold needs to be cleaned or plated;

Fourth, the operation method when demoulding is wrong

Many mold masters have not undergone professional training or work at the time of demoulding. If they are not demoulded according to the strict work instructions, the silicone buttons will be broken. This requires professional operation skills training or strict operation for the operators. system.

Five, the silicone button release is not good when the model is used

Lead to the rupture of the product during the demoulding process. At this time, it is necessary to spray an appropriate amount of release agent on the surface of the mold to continue production;

Sixth, the button silicone used is too bad

Some factories blindly reduce the cost of using inferior button silica gel raw materials, resulting in poor quality of the silicone button produced, the rubber is too poor, the toughness is not good, the memory is broken, very normal. To solve this problem, you need to replace the better button silicone.
