The hardness and softness of silicone products will seriously affect the normal use, so the manufacturer should try to make the product hard and soft to achieve the best hand feeling and moderate hardness during production. This has a lot to do with the phenomenon that the hardness of silicone products does not meet the requirements and the phenomenon of local hardness differences occurs during production. The main reason is caused by some problems in the molding and vulcanization process. It can be related from the machine equipment and personnel control. Today I will talk about why the hardness does not meet the standard and how to deal with it.
Reasons for the hardness of silicone products not up to standard:
1. For this situation, it is caused by the production reason of the silicone product manufacturer itself. When the guaranteed raw materials and machine equipment are all normal, it is caused by the production of personnel and the problems of the times.
2. Generally, manufacturers of silicone products will confirm the hardness requirements of the samples required by customers, and how many degrees of raw materials are mixed to ensure that the hardness requirements required by customers can meet the standards before mixing. After mixing, the temperature on the machine equipment After the adjustment is completed, both the pressure and the hole discharge are completed, and the optimal effect can be achieved after determining the vulcanization time, so after the full inspection is completed, the reason can be found from the operation method.
The hardness of silicone products does not meet the standard solution:
1. In terms of the hardness of the product, it does not need to be too hard or too soft. Generally, silicone rubber products are adjusted in terms of time to make enough and large products to adjust the time appropriately.
2. Check whether the product can reach the hardness according to the products of the previous molds. If it is not enough, increase the mold temperature by two or three degrees, and increase the time. If the hand feels too hard and too brittle, it will lead to future practical use. easy to break,
3. The time can be appropriately reduced to increase the output. If the time is reduced or it is too brittle, then only lower the temperature until there is no bad phenomenon of air bubbles.
