| Abstract: |
| The rubber/metal composite structure of high-precision valve core and its adhesion property
were introduced，the relationship between the forming process and sealing performance of high-precision
valve core was analyzed，the sealing solution of the valve core produced by each forming process was
presented，and reasonable suggestions were recommended for the molds and tooling involved in the forming
process. The forming process technology could be used as a reference for the development and production of
various valve cores and rubber/metal composite structure parts |
