Ultrasonic horn stretches and shrinks in length during the welding process like a spring. For example, a 20 kHz horn is typically a one-half wavelength long resonant bar, whose molecules are constantly expanding and contracting 20,000 times per second. Consequently, the horn is continually under compression or tension. That’s why, for manufacturing ultrasonic horns –… Continue Reading What material is best for making Ultrasonic Horns?

The use of various plastics in manufacturing has grown immensely in the last 15 or so years. Weight savings, optical requirements, and flexibility to name a few reasons push the envelope of legacy materials and often times leave plastics as the only logical choice to meet design requirements. Continue Reading 12 Advantages of Laser Plastic Welding

Assembling medical devices and other medical components are demanding.  Consistently producing good parts, in a validated process, while recording, storing, and analyzing data points is imperative.  Utilizing an ultrasonic welding process for assembly is widely accepted for medical devices and components because it is a fast, clean, easy to validate, repeatable assembling process. However, the… Continue Reading Reduce Flash, Get Stronger Welds, & Lower Residual Stress with Dynamic Weld Velocity

Melt-Match® is known in the plastic industry to improve all the phases of the plastic welding process with servo-driven control and precision. Check out the following video showing the difference between pneumatic vs servo ultrasonic welding with patented Melt-Match®. Improves confidence in total quality with a tighter standard deviation of dimensional accuracy and weld strength… Continue Reading Benefits of Melt-Match®

Mastering the 4 pillars of Laser Polymer Welding using 1 micron Laser will provide an excellent foundation for you to design-in the technology. Pillar #1 – IR (Infrared) Transparent Upper Layer The first layer of material that the laser beam encounters (the IR Transparent Layer) must allow a certain portion of the laser energy to… Continue Reading The 4 Pillars of Laser Polymer Welding using 1 micron Laser

Infrared Imaging Systems: Test weld joints, bonding integrity with IR imaging. Infrared Imaging system works hand in hand with Dukane’s Laser Welding systems. They provide machine vision inspection through a standalone inspection unit or placed in an assembly line. With the fairly recent adoption of laser plastic welding as a technique for joining plastic components, the need… Continue Reading Infrared Imaging Inspection to Test Weld Joints and Integrity of Laser Welded Plastic Parts
