15 Things You Should Know Before Embarking On Piezoelectric Ceramics

                    15 Things You Should Know Before Embarking On Piezoelectric Ceramics

For the common problems of ultrasonic welding production process , we can get through the following points to be improved. Improving the PZT material flexible piezoelectric of ultrasonic welding fixture is mainly from the role of position and bearing. For aircraft piezoelectric disc transducer of products with complex three-dimensional surface shape and high machining accuracy requirements, the accuracy of ultrasonic clamps on piezo elements sounder sensor  has higher requirements.Piezo elements transducer used for ultrasonic welding and the piezo disc crystal PZT 5 of product is not welded when the angle or curvature is not easy to cause deformation of the product after welding. General fixture material of piezo disc transducer PZT is aluminum alloy, fixture according to product to be welded after profiling, you also need to fine-tune to change the natural frequency of fixture which makes its frequency and ultrasonic welding machine with the best welding effect.Such fixtures generally require professional ultrasonic welding machine manufacturers or institute of acoustics processing. Easy to shock, broken products, welding fixture should be used to soft resin or covered cork and other buffer design. Not easily broken products, through the ultrasonic welding fixture surface treatment (hardening or chrome plating) can improve the welding quality. Conditions are adjusted to be ultrasonic welding,which are the machine output power, dynamic pressure and static pressure, welding time, hardening time, delay time and other elements of the setting. By optimizing the conditions of ultrasonic work can often get the ideal welding effect.
