PLASTICS

High Strength Joining Of Thermoplastics

Herrmann Ultrasonics provides highly advanced technologies and a variety of patented solutions for the ultrasonic joining of thermoplastic parts.


How Does Ultrasonic Welding Work?

The ultrasonic welding process uses high frequency mechanical sound waves (ultrasonics) to create molecular heat between thermoplastic materials. These high frequency acoustic vibrations are transmitted through thermoplastic material by a sonotrode. Typically two parts are located and supported in a fixture beneath the sonotrode. The sonotrode extends and applies a clamping force (pneumatic) to the parts. Localized frictional heat is generated at the joint area (energy directors) creating a molecular bond between the two parts. Typical operating frequencies are: 20 kHz, 30 kHz and 35 kHz. For more information about the function of plastic welders please see "Fundamentals of Ultrasonics"


Advantages And Benefits Of The Plastic Welding Process

Using ultrasonic plastic welding, no adhesives, screws, connective bolts or soldering materials are necessary. The possibilities for ultrasonic applications are broad. The process is very fast (less than one second) and can be automated very easily. The machines can be installed anywhere since no exhaust or heat has to be removed and therefore no ventilation system is required. The applied heat occures only in the joining area, avoiding any temperature changes or surface damage to the plastic parts. The joints are repeatable, clean and precise.
