Graphical Analysis Helps Find and Fix Ultrasonic Welding Problems

摘要

Ultrasonic plastic welding uses acoustics(mechanical sound waves)to create frictional heat,producing a molecular bond between plastic materials.The essence of process control for ultrasonic welding is to introduce mechanical vibrations into the plastic parts utilizing a specific amplitude,force,and duration.Research has proven that the consistency of the melting rate has a direct influence on bond strength.The more linear the joining velocity profile,the steadier the melting rate,the more homogeneous the molecular structure of the melt,and the stronger the weld.
