Ultrasonic Welding Machine
Case: Our customer, a major medical technology company, was launching a new blood collection product line. Unlike conventional blood collection devices or containers this product is composed of a multi-piece device which required TPD to develop an automated machine to assemble. The cycle time to fully assembly the device was 20 parts per minute (1,200 part per hour). Read more
Solution: Tri-Power (TPD) built and supplied a machine, via an 8-position indexing dial, which is capable of ultrasonically welding a dispenser body, capped with a dispenser tip, with the resulting assembly containing a single ball, within a cycle time of less than 3 seconds.
Design Challenges: The Machine’s performance requirements included a max scrap rate of not more than 1 damaged / incomplete weld part assembly per 600 parts. Moreover, assembled parts needed to be free from defects as observed under 10x magnification. Lastly, acceptable ultrasonic welds needed to be free of flash, with no stress marking or functional part markings with a Machine long-term annual capacity of 2.5 million units per year.
