In the sealing process, we often use special parts for sealing, because of its shape and was named O ring, O ring because of its shape for the ring, and the section is round and named, this shape is conducive to compression, easy assembly, but its production process to follow certain principles, is the mainstream product of sealing boundary.
At the time of making the seals, usually considering the compression ratio of this parameter, this parameter determines the relative reserved seal industry qualitative placed a size, also is the placement of seal ring groove, if the master is not good, to seal cannot come true without leakage of the seal, may also be made to pack, pack is not ok to do, heating can be improved, not seal will have to redo.
Another factor to consider is to should as far as possible make the maximization of the sealing ring contact surface, the larger the area of the sealing performance, the better, but the area is large and installation problems, besides, still have to make the friction (dynamic sealing) are reducing as far as possible, do big friction can directly lead to seal produce permanent deformation, difficult to continue to use.

When making, adopt the way of high temperature injection or extrusion forming and plastic fabrication process of the difference is not too much, here no longer say more, but not the underlying batch of making necessary scientific, usually one or two or even a dozen, mold or want to do, but not high temperature extrusion and injection forming way, but under normal temperature with glue and mixed curing agent, into the mold, Close the mold again, wait about 24 hours, open the mold again, and you are basically done.
