3-Dimensional Curved Surface Type Piezoelectric Transformer and Manufacturing Method Thereof

摘要

The present invention provide a piezoelectric transformer which is characterized in the surface of the three-dimensional curved surface shape, is the forming body and the body electrode in addition to the respective upper and lower first and second curved surface composition of a piezoelectric material, the normal strain and shear strain occurs at the same time do. A piezoelectric transformer in this case is a mixture with the manufacturing process (first process) of mixing the binder and the ratio produced by a constant injection moldable pellets; Injection molding process for producing a molded article by injection molding into a mold of a desired shape (the second step), and; Produced by the powder injection molding method comprising the sintering the binder removal step (third step) and deionized delay for producing a de-lag by removing the binder from the injection molded high temperature in the sintering process (fourth process) for producing the final product and the features. ; Injection molding, PIM, the piezoelectric transformer, a three-dimensional shape, the vibration mode
