Servo Step 14 - Post Weld Settings
Continuing with the Process Settings tab. . .
The post weld phase of the process is often overlooked,
however it is important in achieving desired weld results.
The iQ Servo Welder has several exclusive post weld
control parameters that can improve weld bond strength
and process repeatability.
Hold
There are two types of hold - Dynamic Hold and Static
Hold. These types can be used together or separately.
Dynamic Hold Method
During Dynamic Hold, with Collapse Distance enabled,
the actuator will continue to travel the programmed col-
lapse Distance at the programmed speed with the ultra-
sound signal turned off.
This occurs immediately after the weld phase. This unique
feature provides the ability to collapse the molten plastic
after the ultrasonic signal is turned off, before material
solidification. This feature can be beneficial in producing
superior weld strength and appearance.
