Reduce Flash, Get Stronger Welds, & Lower Residual Stress with Dynamic Weld Velocity

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

What is Melt-Match®?

A patented plastic welding process to repeatably detect melt transition from solid to molten state, then accurately controlling the melt flow of a thermoplastic material during the weld and transitioning from the molten to solid state. Melt-Match® is known in the plastic industry to improve all the phases of the welding process with servo-driven control… Continue Reading What is Melt-Match®?

Composite Horn – Ultrasonic Welding

Ideally, in ultrasonic welding the area where the horn contacts the part should be as close to the part joint as possible. However, at times, odd-shaped and sized parts prevent a half-wave horn from contacting the part where needed or developing sufficient amplitude to weld the application. In these situations, the answer is to use… Continue Reading Composite Horn – Ultrasonic Welding

Quick Tips and Tricks – Vibration Welding Process

Improve your Vibration Welding Process with these Quick Tricks and Tips: Get consistent weld quality with Weld by Distance mode, the only closed-loop welding method. Even if the weld force, amplitude, or the surface area of weld changes due to inconsistent part molding or design gap, the machine welds by the same distance. If the… Continue Reading Quick Tips and Tricks – Vibration Welding Process

Emerging Technologies: An Introduction to Particulate Free Welding

Eliminate particulate from your welding process and produce cleaner plastic parts with stronger welds and better aesthetics by using technologies designed to heat plastic parts and create a molecular bond between two pieces without generating any particles during the process. What do you get? Stronger welds by using contact less and targeted heat sources to… Continue Reading Emerging Technologies: An Introduction to Particulate Free Welding

Key Advantages of Vibration Welding

Clean, fast, well suited for joining large parts, and the ability to produce high-quality joints without fasteners or adhesives are few of the many benefits that make vibration welding a popular joining method for manufacturers producing plastic parts for automotive, appliances, home improvement, and several other industries. Flexibility to join a variety of plastic parts:… Continue Reading Key Advantages of Vibration Welding

Reconditioning the Ultrasonic “Stack”

The ultrasonic “stack” is made up of three components: the transducer, booster and ultrasonic horn. The quality of the mating surfaces between these three units will have a major impact on the operating efficiency of your ultrasonic welding equipment. If they are not flat, if they become corroded or they make poor contact, they become… Continue Reading Reconditioning the Ultrasonic “Stack”

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

Equipment for Bioplastics Characterization Lab

Dukane Corporation donated a pneumatic ultrasonic welder and loaned a servo-actuator controlled ultrasonic welding system to David Grewell’s bioplastics research group. The new equipment will be used to study various control algorithms for cutting polylactic acid (PLA) films. They were installed in the Bioplastics Characterization Lab, part of the suite of research labs operated by… Continue Reading Equipment for Bioplastics Characterization Lab

Ultrasonic Staking 101

QUESTION: In a staking operation, I want the stud to melt at the face of the horn to form a rivet head. Instead, it’s melting at the base of the stud. What’s going on? ANSWER: A couple of things. First, energy is transmitting through the stud to the base. Try pre-triggering the system so that… Continue Reading Ultrasonic Staking 101

Ultrasonic Boosters

The boosters serve two purposes; second mounting point for the stack assembly and either amplifying or reducing the amplitude.  Like the transducer, the boosters have a nodal point.  At the nodal point there is a mounting ring designed to fit into the press system or machine mount applications.   There are two types of mounting ring… Continue Reading Ultrasonic Boosters

The 6 quick steps to a successful ultrasonic assembly

Do you have an application that you think could be ultrasonically assembled? Wondering how to get from a couple of pieces of plastic to an assembled part? This is how our sales engineers tackle an application. While we don’t expect our customers to perform each of these steps, it’s important they be involved in this… Continue Reading The 6 quick steps to a successful ultrasonic assembly
