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 phenomenon of local hardness differences in silicone products produced by manufacturers that do not meet the required hardness requirements. The main reason is due to some problems that occur during the molding and vulcanization process. While ensuring the hardness of the raw materials of the product, it can be related to machine equipment and personnel control.

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:

1. In terms of product hardness, 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 product confirmation of the previous models, check if the product can achieve hardness. If it is not enough, increase the mold temperature by two or three degrees, and prolong the time. If the hand feels too hard and too brittle, it may 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.
