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

Dukane’s Technical Seminars

Have you heard the story of the man who is working feverishly to cut down a tree? He had been working hard for hours when a passerby suggested that his work might go faster if he would take a short break to sharpen the saw. “I don’t have time to sharpen the saw,” the man… Continue Reading Dukane’s Technical Seminars

Plastic Welding Technical Tip – Weld them while they are hot

Molded parts welded hot off the press will weld differently than if they are allowed to cool. Since these parts are not fully cured, their size and shape can change significantly in the first few minutes out of the molding machine. Freshly molded parts may also retain quite a bit of heat, which can be… Continue Reading Plastic Welding Technical Tip – Weld them while they are hot

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

Using a Buffer Sheet in the Ultrasonic Welding Process

Appearances matter, and your reputation may depend on that. These days every edge in making consistently appealing and attractive parts is important. So, here’s where the idea of using a buffer sheet in the ultrasonic welding process comes in. What is a buffer sheet anyway? Basically it is a thin film – think sandwich bag… Continue Reading Using a Buffer Sheet in the Ultrasonic Welding Process

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

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

Dukane Announces ISTeP – An Advanced Test Part

Dukane Corporation has taken a significant step to improve the ultrasonic industry’s standard test part. They’re calling it the ISTeP, a two-piece cylindrical part used to test a variety of welded parts’ characteristics. With ISTeP, ultrasonic weld quality and reliability can be determined with enhanced confidence. Outside the I-beam – By rethinking the design of… Continue Reading Dukane Announces ISTeP – An Advanced Test Part
