Dukane Corporation (www.dukane.com) has announced the expansion of its iQ servo-controlled ultrasonic welding systems portfolio for medical applications and other high-value components at the 2011 Medical Design and Manufacturing West exhibition.

The company now aims to provide high-frequency welders ranging from 30 kHz to 50 kHz for smaller medical parts such as ports, valves, implant components and filters.

Meanwhile, Dukane’s larger press platform (super 20 kHz and 15 kHz) aims to cater to larger part sizes for medical applications. Dukane’s new welders feature new Melt Match technology, which offers stronger welds, greater repeatability, lower manufacturing cost and easier calibration versus standard pneumatic welders.

“We’ve expanded our iQ servo welding line beyond the existing 20 kHz model and now offer wide-ranging capabilities and flexibility to meet the unique and diverse requirements of our customers,” said Michael Johnston, National Sales and Marketing Manager.

The company’s smaller press systems ranging between 600 watts to 1800 watts are ideal for high-speed automation and higher throughput. Its larger press platform delivers higher wattage ranging between 3300 watts to 5000 watts and higher clamping force.

Complementing the company’s latest collection of iQ servo-controlled ultrasonic welding systems, the new models utilize a unique method that accurately controls the collapse speed profile while welding. This technology eliminates the problem of collapsing too fast, which often results in cold forming and collapsing too slow, which may cause degradation of materials, by precisely matching the collapse speed during the melt phase resulting in larger heat zone and deeper ultrasonic propagation into the bond area and ultimately in superior bond strength.

The company’s portfolio of iQ servo welders is FDA CFR Title 21 Part 11 compliant and features ultra-rigid support base and a strong mechanical design.
