Silicone Knowledge:
Silicone rubber products need to be trimmed with burrs after molding. In general, they are tearing burrs and trimming edges. Sometimes, due to some factors of raw materials and molding, it is not easy to remove the edges of the goods after molding, and if you are not careful, they will crack or leave burrs. So, what are the factors that make it difficult to remove the edges of silicone rubber products after molding? As a professional silicone products factory in Shenzhen, Yingtai will give you a brief introduction.
First, the quality of silica gel raw materials.
Sometimes, in order to reduce the manufacturing cost, the silicone products factory will choose some relatively cheap glue for production, and one of the most common problems of cheap glue is insufficient tear strength and poor toughness. These silicone raw materials do not have much effect on edge removal in silicone buttons, which are generally less demanding. If it is used for some silicone products with complex structure, it will not only affect the molding performance of molding, but also the burr is easy to break during the edge disassembly, and the edge removal efficiency will be greatly reduced. If you are not careful during the edge removal process, it can easily lead to cracking.
2. The vulcanization temperature of silica gel is too high or the vulcanization time is too long.
Once the temperature of the silicone product is too high when it is formed, it will cause the product to become numb or brittle after molding. Whether it is numb or brittle, it will have a great impact on the subsequent edge removal. Excessive vulcanization time is one of the main reasons for brittleness of products.
3. The vulcanization temperature of silica gel is too low or the vulcanization time is too short.
A vulcanization temperature that is too low or a vulcanization time that is too short can also have an impact on the disassembly of the edges. Silicone rubber products are highly flexible when not fully vulcanized, so it is not easy to separate burrs from the product when removing the edges.
The molding thickness is too thick.
This is the simplest and easiest point to understand, don't explain too much, just try to make it as thin as possible when molding to ensure that the size is qualified.
What is the cause of silicone molds?
The self-disassembly design of the mold is unreasonable or the production quality is unqualified or the mold is damaged due to too long use, resulting in the edge being difficult to disassemble. When designing the mold, the mold designer is unreasonable, and when making the mold, if the self-dismantling is not sharp, it is difficult to remove the edge of the product after molding.
6. Other factors.
Excessive wear and tear of the mold or excessive sandblasting during the production process will also lead to rough self-dismantling openings, which will also affect the self-dismantling performance of silicone rubber products after molding.
