Assembly Demands Grow for Medical Plastics

A study done at Value Plastics, a molder of precision molded couplers for medical applications, shows that a servo welder produces hermetic welds with a standard deviation of 0.4% compared to 2.9% when using a pneumatic welder. Those results were reported last month at ANTEC in Cincinnati, OH by three officials at Dukane Corp., which… Continue Reading Assembly Demands Grow for Medical Plastics

Reduce Residual Stress with iQ Servo Ultrasonic Welder

Even on parts with good weld strength, failure can occur in the field due to residual stresses [A].  With ultrasonic welding, residual stresses are typically in the range of 35 MPa due to the rapid cooling of the small amount of melt [A, B].  Recent experimentation at Turku University of Applied Sciences in Finland have… Continue Reading Reduce Residual Stress with iQ Servo Ultrasonic Welder
