Is there anything we need to mention when making silicone o-ring?

The demand for various products in the silicone industry is very common in major industries, and the solid-state hydraulic process occupies more than 50% of the silicone industry. The most demanded one can be said to be the solid-state molding process, which can achieve high and low levels. Different hardness materials, and the hardness of the hardness also affects the normal use of the product. Some silica gels often require high hardness materials in daily life, and silica gel like rubber rings will cause some problems when the product is high in hardness. 

High hardness does have certain technical requirements in the industry of silicone products manufacturers. Firstly, see whether the development structure of the mold has a certain impact on the vulcanization of the product, and secondly, is the exhaust groove of the mold really pulled? And the most important thing is whether high hardness products can meet your needs?

Some customers often want about 60 degrees, but they can’t distinguish the hardness of the hardness and can only guess, so the use of 70.80 hardness affects the normal use of the function, while some friends want 90 degrees of material, but verbal The above instructions only need 70 degrees, 80 degrees is enough. As a result, after the mold is opened, the silicone hardness of the product made does not meet the requirements, so it is more important to understand the softness and hardness of the product. There is a reason why it is divided into ±5 degrees instead of ±1 degrees.
For high-hardness silicone seals in the production process, you need to shorten the time and reduce the temperature. Try to reduce the processing hardness and retain the essential hardness. If the curing time is too long, your seal must be very brittle and easy to tear , You must pay more attention when using it. If your temperature is too high, the probability of edge tearing of the product will increase, and the aging rate will gradually increase.

Therefore, high-hardness products still need certain processing skills in the processing process. The main difficulty is actually the self-removing edge of the mold and the exhaust groove. As long as the product scheduling effect can be achieved, there is basically no problem after adjustment on the machine.
