Product implementation of ultrasonic operations can not be achieved water, airtight, in addition to ultrasonic fusion line, fixture positioning, product positioning and other factors, ultrasonic setting conditions is also a major cause. We are here to explore more in-depth lead to ringing water and airtight another reason (fusion conditions), in our implementation of ultrasonic fusion operations, seeking efficiency and speed is the most basic goal, but often also ignored the essentials of its efficiency, there are two normal phenomena: 

First, the speed of decline, buffer too fast: the formation of this speed, so that the dynamic pressure coupled with the acceleration of gravity will be the ultrasonic fusion wire flattened, so that the fusion wire can not play the role of fusion, the formation of false phase fusion.

Second, the fusion time is too long: plastic products due to receive too long a period of time of heat, not only make the plastic material melting, and then cause the plastic organization of the phenomenon of scorching, resulting in sand holes, water or gas that is permeated by the sand holes out. This is the general production technology is the most difficult to find.
