Dukane Announces Expansion of Servo-Controlled Ultrasonic Welding Line
New Small Press and Large Press Models Meet Diverse Needs of Medical Market
ANAHEIM, Calif., February 8, 2011 - Dukane has expanded its novel line of iQ servo-controlled
ultrasonic welding systems for medical applications and other
high-value components. New high-frequency welders (30, 40, and 50
kHz) are targeted for smaller medical parts such as valves, ports,
filters, and implant components. Meanwhile, a larger press platform
(15-kHz and super 20 kHz) targets larger part sizes for medical
applications. These new welders also employ the company�-s new Melt
Match technology which delivers greater repeatability, stronger
welds, easier validation calibration, and lower manufacturing cost
versus standard pneumatic welders. Dukane made the announcement here
at the 2011 Medical Design & Manufacturing West exhibition (booth #
2819) Feb. 8-10.
"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," says Michael Johnston, national sales and marketing manager. The smaller press system ranges from 600 to 1800 watts and is well suited for higher throughput and high-speed automation. The larger press platform provides higher clamping force and wattage ranging from 3300 to 5000 watts.
The new models complement Dukane's recently introduced line of iQ servo-controlled ultrasonic welding systems which are an industry first. They use Dukane's Melt-MatchTM technology, a unique method that precisely controls the collapse speed profile during the weld. Collapsing too slow may cause material degradation while collapsing too fast may result in cold forming. Melt Match is unique because it precisely matches the collapse speed during the melt phase. As a result, the ultrasonic propagation penetrates deeper into the bond area and the affected heat zone is larger, resulting in superior bond strength.
This high repeatability results in fewer rejects for manufacturers. In fact, testing shows that the average standard deviation of the bond strength for filter housing parts welded on a servo unit was 1.8% compared to 6.6% for those welded on a pneumatic machine.
The iQ servo-controlled welders also offer more consistent part height unlike pneumatic welders whose continuous travel during the hold phase may affect part height. The iQ servo welder controls the entire process, - according to Johnston, and thus the collapse standard deviation of the iQ welder is three times better than that of a pneumatic machine.
Melt-Match technology is driven by Dukane's new patented iQ series digital power supply, the fastest in the industry. It boasts a data processing rate of 0.5 ms which is twice as fast as competitive systems. The technology also offers an important advantage for OEMs such as medical device manufacturers who must verify that weld process controls are in tolerance. The iQ unit incorporates a true programmable servo drive mechanism for speed control. As s result, validation of the servo motion is simplified. This compares to pneumatic welders that attempt to control the weld speed via air pressure through a proportional valve device. This can be problematic because actual collapse speed during welding is a variable and validating the air pressure does not ensure that collapse speed is accurate and consistent, according to Dukane.
The family of iQ servo welders are compliant with FDA CFR Title 21 Part 11 and feature a robust mechanical design and ultra-rigid support base. There are no operator-accessible settings and all mechanical adjustments require a tool. The elimination of compressed air helps to reduce clean room air filtration and significantly lowers manufacturing cost.
