Silicone mold production durable method to share

When we use silica gel mold, in order to save costs and improve work efficiency, of course, we hope that the silica gel mold can be turned over more times and have a long service life. So how can we make the service life of silicone mold production increase, ensure that the use of silicone mold is more durable! The following Kemet silica gel to share with you a few: one. According to the size of the model product to choose the mold or brush mold.
If the size of the product is very large, it is necessary to use the brush mold, although the irrigation mold saves labor, time and effort, but it is very expensive.
Because so big product USES the irrigation mode, waste silica gel increased costs, and the heavy products will be easy to crush the silicone mold lead to deformation or fracture, but you can choose to brush mould inside add several layers of gauze can improve mould toughness and strength, coupled with the external formwork support natural does not easily crushed or pressure.
two According to the size of the product to choose the appropriate hardness of silica gel.
1. Small products, generally soft silica gel is more suitable. Because the mold will be very brittle when the silica gel is too hard, it is easy to break off the small parts of the product, which will also cause the mold is not durable.
2. Large products, such as stone cement products themselves are so hard and heavy. If soft mold silica gel materials are selected, isn't the mold more likely to be crushed? Because silica gel is too soft, its tension and tearing strength will be reduced, the mold will be deformed, and the service life will be reduced naturally.
3. Silica gel and curing agent to stir evenly.
Otherwise, there will be dry or uneven curing, which will cause the scrap of the mold, and we should try our best to avoid it.
