Temperature Control Technology in Flexible Rubber Joint Manufacturing

 

Control the temperature of mold when putting in semi-finished rubber joint body to guarantee a smooth and good looking surface.

 

Temperature of every part of the mold are basically the same, with maximum tolerance 3 ℃. Thus air blow molds can only be used for small diameter flexible rubber joints below DN800. Large diameter flexible rubber joint will be made by split type molds in warming and vulcanization, to ensure the same temperature and rubber body quality.

 

Usually there is no surface blister or bulging in flexible rubber joint manufacturing. But if the internal air is not emptied in semi-finished flexible rubber joint body production, it will happen.
