Silicone mold is made of silicone as raw material. No matter what kind of silicone mold, there will be a little shrinkage, and the degree of index shrinkage is different. The shrinkage has little effect on which products are not very precise. After all, the degree of shrinkage is very small. .

Silicone molds include molds made of industrial-grade silicone and molds made of food-grade silicone. The degree of shrinkage varies according to their types. Industrial grade silica gel is a condensed silica gel with a shrinkage rate of less than 0.2%. The properties of condensed silica gel depend on the degree of vulcanization and the additives used. Food-grade silica gel is an addition type silica gel with a shrinkage rate of less than 0.1%. Food-grade silica gel is a safe and healthy silica gel, mainly used in tableware applications. Its structure is stable and is an inorganic polycondensation of silicic acid Polymer Materials. Generally speaking, the effect of shrinkage of silicone molds is very small, unless some large molds will have some impact, but if normal maintenance is good, shrinkage can be avoided.

Precautions:
1. The silica gel mold should be stored in a dry environment, because silica gel is a highly absorbent material.
2. When demoulding, the mold should be completely cured before going out, otherwise it will cause deformation and shrinkage of the silicone mold.
3. When using, you should read the instructions and make the mold according to the manufacturer's specifications. The silicone mold is formulated according to the manufacturer.
4. The bigger the silicone mold, the easier it is to shrink, so you should be careful when using it.
5. You can use gauze to prevent the mold from deforming and shrinking.
6. After using the silicone mold, it needs to be cleaned in time.

Some silicone molds are used in a special environment. It is normal for molds to shrink after long-term use. With the advancement of technology, many silicone molds now have very good anti-shrinkage characteristics. It is recommended that you choose manufacturer customization when purchasing silicone molds The purchase can ensure the quality assurance of the bulk purchase of silicone molds.
