What are the difficulties in making silicone waterproof ring?



The demand for silicone waterproof ring is very common in all major industries, so do you know the difficulty of making silicone waterproof ring? Let the staff of the silicone waterproof ring manufacturer introduce to you.



Silicone waterproof ring does have certain technical requirements in the industry. First, see whether the development structure of the mold has a certain impact on the product vulcanization, and secondly, is the exhaust groove of the mold really stretched? And the most important Is the high hardness product able to meet your needs?










Some customers often want to be around 60 degrees, but they can’t distinguish the hardness of the silicone waterproof ring. The hardness of the silicone waterproof ring can only be guessed. Therefore, the hardness of 70 and 80 affects the normal use function, and some friends I want a 90-degree material, but verbally stated that only 70 degrees is needed. 80 degrees is enough. As a result, the hardness of the silicone cannot meet the requirements after the mold is opened. Therefore, it is more important to understand the hardness and softness of the product. There is also a reason why the degree of hardness is divided into ±5 degrees instead of ±1.



For high hardness silicone waterproof ring in the production process, you need to shorten the time and lower the temperature, try to reduce its processing hardness, and retain the essential hardness. If the vulcanization time is too long, your silicone waterproof ring must be very brittle , It is easy to tear, so pay more attention when using it. If your temperature is too high, the probability of corner tearing of the product will increase, and the aging rate will gradually increase!



Therefore, the high hardness silicone waterproof ring still needs certain processing skills in the processing process. There are difficulties. In fact, the most important thing is the self-disassembly of the mold and the exhaust groove. As long as the exhaust effect of the product can be obtained, there is basically no problem after adjustment on the machine.



The above is the difficulty of making silicone waterproof ring. I hope it can be helpful to you. If there is anything you don’t know, you can directly communicate with our customer service. We will serve you wholeheartedly and thank you for watching.
