Structure and manufacturing process

*  Porcelain Core: manufactured with high alumina porcelain 

    raw materials;

*  Silicone Rubber Sheds: HTV silicone rubber, with alternative        shed profile；

*  With the high pressure injection molding at high

    temperature, the silicone housing is fully bonded to the

    porcelain solid core which cemented fitting in advance.

   The silicone housing adheres directly to the fitting without  the

   need for artificial sealing;

Feature

* High mechanical strength with much lower of deflection

*  Excellent performance of anti-pollution;

*  Long lifetime is guaranteed;

     *  Maintenance expenditure is reduced to a minimum;
