At NPE2018, Herrmann Ultrasonics Inc. (Booth W8153) will focus on how its ultrasonic welding technologies can help manufacturers wanting to increase machine efficiency to save costs.
Herrmann suggests a processor can "limber up your process" through use of its flexible ultrasonic manufacturing systems.
Those include the configurable Vario series, which provides multiple pneumatic drive modes with different stroke designs along with programmable proportional valve technology.
Demonstrations of the HiQ Vario with a radio-frequency-identification reader will allow visitors to see how the technology works.
Generators are available in three frequencies and several power ratings of up to 6200 watts. Set-up and change-over times can influence the efficiency of manufacturing.
Herrmann says the Vario product line can significantly reduce these times. With the help of Herrmann's quick-change system, the aligned weld tools can be changed to a new application in less than a minute. That includes the Vario control weld process data. The integrated controller can store up to 32 different weld applications.
A Vario welder makes it possible to program a variable weld force in two stages. A controlled build-up of the plastic melt creates an ideal condition for welding at maximum strength and tightness, and the force switch-over is implemented through a proportional valve that has been specifically configured for this type of precise and fast control.
Manufacturers using the Vario for different devices will benefit from new safety measures that add production security.
The integrated RFID reader — built into both the sonotrode and the fixture — guarantees that the correct tool is installed for the production.
The ultrasonic welding system automatically associates the correct parameter setting for parts to be welded with the installed tooling.
An integrated custom sensor adds a second level of security allowing a manufacturer to detect color, label, shape or other feature. The sensor can verify placement of the correct part in the fixture.
Recognition of a mismatch locks the process, alarms the operator or puts the system on hold.
Both the reader and sensor can be integrated into Herrmann's HiQ series ultrasonic welding machines or VE actuator series.
Herrmann, headquartered in Bartlett, Ill., is an operation of Herrmann Ultraschalltechnik GmbH & Co. KG of Karlsbad, Germany, which started in 1961.
