Precautions for making liquid silicone compound mold

Liquid silicone molds are the materials of choice for many manufacturers, but some problems are easily overlooked during the mold making process.
The first is to deal with the problems. Many customers are always worried that the surface of the mold is not smooth and does not look good. In fact, this problem has a lot to do with the smoothness of the surface of the mold. The mold should be smooth, or the mold can be cleaned before pouring. The mold can be smooth and clean. .

Second, the proportion of curing agent added. Most factories who use silica gel rely on experience to add curing agents, rather than weighing by electronic scales, because the proportion of curing agent directly affects the customer's operating process and mold performance. Therefore, the added amount of curing agent must be weighed by an electronic scale to obtain detailed data.

Third, the problem of silica bubbles. After the silica gel and the curing agent are mixed and stirred evenly, a large amount of bubbles will be generated in the silica gel. The customer always wants to think that the silica gel is free of bubbles, but when it is actually used, it will definitely produce bubbles. To completely eliminate air bubbles, it can only be achieved by defoaming by external force of a vacuum machine. It is also possible to achieve the elimination of a small part of the air bubbles by reducing the proportion of the curing agent added.
Fourth, the time to disassemble the silicone mold and the time to use the silicone mold. When the silicone mold is cured, the mold can be dismantled, and the silicone mold is actually used for production. It is recommended to wait for 24 hours after the mold is cured for release production.
