RUBBER BONDED VALVES


Shanghai Tian Tian Rubber & Plastic Co., Ltd. has rich experience in bonding rubber on metal or plastic inserts. With strict supplier management and rigorous process control, we can assure the proper bonding between the two different materials from all aspects, like the metal inserts of right properties, proper bonding agent and professional rubber compound.


The rubber part is critical in such valves. Besides reliable seal-off in the specific environment, its mechanical properties, temperature behavior, chemical resistance, etc. all plays important role.



METAL INSERT DESIGN


The properties of the metal inserts are extremely important. Tian Tian follows strict supplier management system and well-designed testing standards with professional facilities to assure its dimensions, roughness, edges and cleanliness be the same at all times. The metal materials in use are usually aluminum, brass, steel, thermoplastic, and thermoset materials.



BONDING AGENT


The bonding agent used is tailor made for the application by our material engineers. The bonding agent plays important role in assuring the proper bonding of the rubber on the insert.



RUBBER COMPOUND


Like the bonding agent, the rubber compound used is also developed by our material engineers. The compound needs to be designed as such that after pressing not only the correct sealing properties are accomplished but also the rubber is bonded firmly to the metal. Tian Tian offers co-development in design of the complete valve.



PROCESS


The chemical bonding requires the metal surface to be cleaned ultrasonic, blasted and applied with a bonding agent only at those places where rubber should be added. Hereafter the rubber is molded onto the product. At the moment, the replacement of metal by plastic is also in place. In our sample show, you will see those rubbers bonded with either metals or plastics.
