Dukane’s iQ Series Servo Driven Ultrasonic Welder, with patented Melt-Match® technology, has a proven track-record of delivering quality results in welding medical parts like valves, ports, filters, surgical instruments and implant devices. iQ Servo’s patented process control features like Melt-Detect™ confirms the presence of the molten material in the contact area before prompting the press to initiate downward movement. This is especially important in welding small parts and assemblies, which requires hermetic seal, as it eliminates the risk of deforming the energy director before melt is initiated, which could result in a leak path and “cold welds”.

The Melt-Detect™ also enables a user to accurately establish the necessary amplitude required by specific material properties and part configuration by using welder’s graphical output. This authentic approach for amplitude setting allows the user to apply just the right amount of ultrasonic energy that is needed to initiate the melt, avoiding excessive heating and material degradation in the weld. This is especially important for building filter assemblies, where excessive amplitude is associated with tiny pin-holes occurring in the filter media.

Watch Dukane's Laser Welder in action
Dukane’s Laser welding systems are capable to weld clear-to-clear and clear-to-colored parts, including typical tube-to-tube-and tube-to-port assemblies. In general, the laser welding technique is dependent on the upper component being transparent to the laser and having the presence of an absorbing agent in the lower component. This configuration limits the process applicability for manufacturing medical devices when a "clear-to-clear" or a "clear-to-colored" assembly is required. Dukane engineers have successfully overcome this obstacle by integrating a recently developed 2-micron laser. This laser produces a beam which is greatly absorbed by clear polymers and enables a highly controlled melting through the thickness of optically clear parts. This has resulted in a greatly improved and simplified technique for laser welding of clear polymers for the medical device industry, which now can fully capitalize on benefits of this advanced Laser assembly process.
