The problems and solutions of hardness during the production of silicone products

The hardness and softness of silicone products can seriously affect normal use, so manufacturers should strive to achieve the best hand feel and moderate hardness during production. This is closely related to the fact that the hardness of silica gel products does not meet the requirements during the production of the manufacturer and there are local hardness differences. The main reason is that some problems occur during the molding and vulcanization process, but it can basically be related to the machine, equipment and personnel operation under the condition of ensuring the hardness of the raw materials of the products.

Reasons for substandard hardness of silicone products:

1. For this situation, it is caused by the production reasons of the silicone product manufacturer themselves, while ensuring that the raw materials and machine equipment are under normal conditions, it is caused by personnel production and era issues.

2. Generally, silicone product manufacturers will confirm the hardness requirements of the samples required by customers by mixing the raw materials to ensure that the hardness requirements required by customers can meet the standards before mixing. After mixing, the temperature adjustment on the machine equipment is completed from the pressure and hole discharge, and the vulcanization time is determined to achieve the optimal effect. Therefore, after the full inspection is completed, the reason can be found from the operating method.

Solution for hardness non-compliance of silicone products:

For the hardness of the product, it does not need to be too hard or too soft. Generally, silicone rubber products need to be adjusted according to the size of the product to adjust the time appropriately. 2. Based on the previous models of the product, confirm whether the product can reach the hardness. If it is not enough, add two or three degrees of mold temperature, and increase the time. If the feel feels too hard or too brittle, it will lead to cracking in the future practical process, 3. If the time can be appropriately reduced to increase production or if it is too brittle, then the only way is to lower the temperature until there is no air bubble phenomenon。
