Using a Buffer Sheet in the Ultrasonic Welding Process

July 24, 2014

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…

Aesthetic Assembly - The Art to Attractive Bonding

July 16, 2013

After carefully molding a beautiful product, nothing is worse than seeing it destroyed during assembly. Every joining process is capable of causing marking, flash, particulate, damage to appendages, or other aesthetic defects. However, with proper part design and processing, a finished weld can be imperceptible or even a cosmetic asset. The art to attractive bonding…

Assembly Demands Grow for Medical Plastics

June 5, 2013

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…

Experiments in Reducing Residual Stress with Dukane’s Servo-Driven Ultrasonic Welder

April 30, 2013

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…

Experiments in Velocity Control with Dukane’s Servo-Driven Ultrasonic Welder

April 11, 2013

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…

Advantages of Servo Ultrasonic Welder

February 22, 2013

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…
