You want to ask knowledgeable friends. I want to do at home produced small seal factory. The former is to buy it do seal butterfly valve. Now they want to engage in their own ring. Do not know what equipment and capital equipment. Then buy new and used funds is how much. Is the production of multi-level sealing ring and PTFE. What materials should I indebted forever
These two are completely different materials, the rubber ring is generally rubber, PTFE is plastic, the production process is not the same. Not familiar with, or first learn more professional knowledge!
It's easy to see things done by others, but when you really get into it, it's not the case. You don't know about the multi-level sealing ring is what is known as the king of PTFE tetrafluoroethylene, plastic. Are you going to make a vinyl sealing ring?
Rubber and PTFE are two different production processes. The main equipment for rubber seals is vulcanizing machine, mixer, cutting machine, testing equipment and so on, and the investment is still very high.
