Type O sealing ring sealing good, almost no leakage when fixed, as a sport, the high speed will only slightly leaking, has been successfully applied in the fields such as cars, but sometimes at the time of production after molding, there will be no continuous, affect the normal use, for that we need to find the reason, and find the corresponding methods.

Type O sealing ring is not shall:
1, the water tank gasket manufacturer to introduce mold temperature is too low. Mold temperature is too low will cause after molding, silicone type O sealing ring is not continuous problems, the solution is appropriate adjust the mold temperature vulcanizing machine.

2, pressure is too large. Stress also can appear after molding, silicone type O sealing ring is not continuous, so in the solution is in the process of operation, adding the right amount of rubber, followed by pressure drop point.

3, rubber. Too little rubber, generally increase the rubber can be solved, only will be charging will make product size larger sense of wrong. Actually, size reduction is not completely rely on reduction of material to solve, you can reduce stress and increase the mold temperature to reduce the size of the product.

4, mold since too sharp sharp. Can be mold to sandblasting, equivalent to mold the open mouth for a polished. But don't do this, because it is a silicone sealing ring of the mold, the mold since the demand is very high, silica gel forming die would have been in the process of constant use wear, if again to sandblasting polishing, it is hard to tear open after waiting for the edge.

Tank gasket manufacturer is introduced to examine the o-ring surface quality, can be made according to standard GB345212-87 rules, including dislocation, open mold shrinkage crack, trimming excess, flow mark, concave and convex defects, etc., usually by visual inspection, found that the problem can use tool microscope or projector, review the material of o-ring are usually identified by simple combustion method, if needs accurate identification, should be sent to the rubber factory do ingredients identification.
