  For a given set of weld parameters, variations in force control that result in applying too little force reduce compression of the mating surfaces, reduce the heat generation needed for plastic melt, and result in cold or weaker welds. Similarly, force variations that result in applying too much force can cause part joints or energy directors to deform, deflect or break and may not provide ...

  Development trend of ultrasonic welding technology   1. Improving welding productivity is an important driving force for the development of welding technology. There are two ways to improve productivity: firstly improve the welding deposition rate, such as three-wire submerged arc welding, the process parameters are 220A/33V and 1400A40V1100A45V respectively. The groove section is smal...

  The fixture material choice will also affect how the plastic material flows at the joint interface. A soft resilient type of material will create a different flow rate than a rigid metal nest. Different fixture materials will create various frictional reactions at the weld joint. An experienced ultrasonic tool maker can assist with choosing the appropriate fixture material. Most of the time...

  The use of CAD/CAM technology has greatly improved the manufacturing of contoured fixtures to support the part during ultrasonic assembly. Exact mirror replicas of the part can be created to provide excellent support to the part. Due to complex contours seen on many parts, it is recommended that the horn and fixture be purchased as a set, so proper alignment is achieved between the two. The...
