Why do silicone products have dimensional deviation?

No matter what product, only accurate dimensions can be used, so the production process of all walks of life requires that the product dimensions are within the tolerance range. The forming of silicone parts also has dimensional requirements and tolerance range. In silicone rubber products, there are many silicone rubber parts with dimensional deviation. How can we control the dimensional deviation of silicone rubber parts in the daily production process? Let's take a look with Xiaobian.

1. When the silicone rubber product is formed: apply a force to the raw material. With a moderate force, we can compress the raw material to a fixed size. Because if the pressure is too large, the thickness becomes thinner and the size becomes larger. Therefore, in terms of forming pressure, we should reasonably grasp a certain degree.

2. Design of the mold itself: if the designed product is not strict and qualified, some errors will be found in any adjustment of the size in production. Therefore, we must pay attention to the precision of the mold when opening the mold, and the size of the product should not have errors. Generally speaking, there are some problems in the mold of silicon products production industry, but we can't rule out this reason.

3. Silicone rubber raw material: sometimes we may put too much silicone rubber raw material. If the volume or weight of silicone rubber raw materials exceeds the volume or weight required for the production of our products, it is easy to make mistakes after the silicone rubber products are formed.
