More options for medical device welding

The Ultrasonics Div. at Dukane Corp. (St. Charles, IL) has just augmented its portfolio of higher-frequency welders (30, 40, and 50 kHz) targeting processing of smaller medical parts such as valves, ports, filters, and implant components.

More options for medical device welding

The Ultrasonics Div. at Dukane Corp. (St. Charles, IL) has just augmented its portfolio of higher-frequency welders (30, 40, and 50 kHz) targeting processing of smaller medical parts such as valves, ports, filters, and implant components.

High repeatability of servo welder results in fewer rejects for manufacturers. Tests show 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 ultrasonic welding systems also employ Dukane's new Melt Match technology, which delivers greater repeatability, stronger welds, easier validation calibration, and lower manufacturing cost vs. standard pneumatic welders, according to the manufacturer. "Our latest iQ servo welders reduce the opportunity to create stress in small, thin-wall components and facilitate optimum welding," says Michael Johnston, national sales and marketing manager.

For precision parts and more delicate components, the new models weld under lower force and thrust capacity. Maximum thrust capacity is 150 lb vs. 560 lb for a recently introduced 20-kHz model. Similarly, the new welders have a trigger force of just 0.1 lb compared to 1 lb for the 20-kHz unit. The new welder also features a stack positive index mechanism that locks in a programmable home position for reduced cycle time and setup optimization.-Stephen Moore
