Ultrasonic horn stretches and shrinks in length during the plastic 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 is the right material for making Ultrasonic Horns?

While you will find 2μm lasers being used in a broad range of industries including automotive, general industrial, films, and packaging, the majority of 2μm welding demand is coming from the medical industry.  Typical laser welding applications include: microfluidic devices, tubing, bags, connectors, catheters, on-body devices, diagnostic cassettes, fluid chambers and tanks, filtration devices, and more.  Microfluidics, diagnostic cassettes, and assays often require components to be transmissive… Continue Reading Which Applications are Best Suited for 2μm Laser Welding?

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
