Servo Ultrasonic Welding assembles Diagnostic Test Strips

A leading medical device manufacturer uses Dukane’s iQ Series Servo Ultrasonic Welding System to produce high-quality results in assembling small, delicate Test Strips.  These Test Strips are used to measure a person’s Total Cholesterol, HDL, Glucose and Triglycerides.  Assembling small medical devices, like these Test Strips, requires precise, repeatable and consistent process control.  The Test… Continue Reading Servo Ultrasonic Welding assembles Diagnostic Test Strips

ISTeP a Standard Test Part for Plastic Joining

The Plastic Welding industry is well aware of the benefits gained from a better weld strength of any plastic material. Whether we are making and delivering medical equipment or packaging for consumer goods, weld strength is the key to achieve customer satisfaction. Dukane’s Industrial Standard Test Part (ISTeP), initially created to test the capabilities of… Continue Reading ISTeP a Standard Test Part for Plastic Joining

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

Velocity Control with Servo Ultrasonic Welder

Even before the introduction of Dukane’s servo-driven welder, the need for velocity control was recognized.  As Mikell Knights wrote in 2005, “Research has proven that consistency of melting rate has a direct influence on bond strength,”  A linear velocity means a steady melt rate which, in turn, creates a homogenous molecular structure and a stronger… Continue Reading Velocity Control with Servo Ultrasonic Welder

Advantages of Servo Driven Ultrasonic Welder

Ultrasonic welding is one of the most widely used processes for bonding polymers, valued for its speed, flexibility, and low cost. Recently, there has been a call for more controlled and consistent ultrasonic welding processes, as part designs become more complex and requirements more stringent.  There is also a need for strong, dimensionally consistent parts… Continue Reading Advantages of Servo Driven Ultrasonic Welder
