Dukane Test Part in Eastman Tritan™ Medical Toolkit

Dukane ISTeP (Industrial Standard Test Part), a two-piece cylindrical part designed to test various characteristics of different resins and plastic welding processes, is the new addition to the Eastman Tritan™ Medical Toolkit. Each application in the Medical Toolkit demonstrates key attributes Tritan™ offers in the medical device and packaging markets. Complex medical devices often require… Continue Reading Dukane Test Part in Eastman Tritan™ Medical Toolkit

Monitor Vibration Welding System with patented ‘Q’ Factor

Dukane’s patented ‘Q’ factor technology for Linear Vibration Welders is an algorithm  to help users monitor and maintain the quality of a welding system over its lifetime. ‘Q’ factor is calculated using the resonant frequency of the welding head  of the vibration welder and the time between which its amplitude reaches its peak and declines to… Continue Reading Monitor Vibration Welding System with patented ‘Q’ Factor

A Success Story about Team Work and Tenacity

Dukane feels honored and proud to be part of the award winning team for Tonneau cover assembly on the 2016 Toyota Tacoma pickup. This winning team in eleven months designed and created a Tonneau cover that is not only flexible and light weight but also provides the required strength and security to the end user.… Continue Reading A Success Story about Team Work and Tenacity

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

Aesthetic Assembly – The Art to Attractive Bonding

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… Continue Reading Aesthetic Assembly – The Art to Attractive Bonding

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

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
