Ultrasonic Welding For Plastics ~ The generator converts the mains network 5060 Hz electrical frequency into a corresponding high frequency electrical energy in this diagram to 20000 Hz. Plastic ultrasonic welding technology is very suitable for plastic hot riveting or heat stacking. Ultrasonic Welding is a plastics welding process in which two work pieces are bonded as a result of a pressure exerted to the welded parts combined with application of high frequency acoustic vibration ultrasonic. In ultrasonic welding there are no connective bolts nails soldering materials or adhesives necessary to bind the materials together. When combined with pressure friction produces heat melts the parts at the horn contact point. This frictional heat is applied through high speed vibration generated in a sonotrode and delivered by a welding horn Ultrasonic welding machines look similar to spot or resistance welders. Ultrasonic welding is a widely recognized and accepted process for joining thermoplastic materials. The same applies for thermoset resins that are processed by curing and cannot be welded by means of ultrasonics. Ultrasonic welding is an industrial process whereby high-frequency ultrasonic acoustic vibrations are locally applied to workpieces being held together under pressure to create a solid-state weld. The 4200W Ultrasonic Plastic Welding Machine We professionally produce standard ultrasonic plastic welding machine such as 2600 W 3200 W plastic welding machine 4200 W 5600 W high power plastic welding machine and other precision welding equipment. Indeed lately has been sought by users around us, maybe one of you. Individuals now are accustomed to using the internet in gadgets to view video and image information for inspiration, and according to the name of this article I will talk about about Ultrasonic Welding For Plastics. Ultrasonic Plastic Welding Ultrasonic energy has been used to join thermoplastics for over 70 years. A horn pushes against the parts being joined applying pressure and energy until they fuse together. The generator converts the mains network 5060 Hz electrical frequency into a corresponding high frequency electrical energy in this diagram to 20000 Hz. When combined with pressure friction produces heat melts the parts at the horn contact point. This technology is also easy to implement in a production process and has a low fault rate. Ultrasonic welding of plastics is used widely in making electronics medical devices and car parts. The longitudinal and torsional methods produce very different welds. The process is based on a conversion of friction and vibration energy into heat. It offers many advantages including process reliability and repeatability lower energy usage than other joining techniques material savings because there is no need for consumables such as glue or mechanical fasteners and labor savings. Longitudinal vibrations in frequencies of 20 kHz 30 kHz and 35 kHz with tool amplitudes between 5 µm and 50 µm are introduced into the plastic materials under the action of force.
The longitudinal and torsional methods produce very different welds. The process is used to produce lap joints in metals plastic sheets and plastic films in varied shapes as wires crossed or parallel ribbons and flat surfaces. The generator converts the mains network 5060 Hz electrical frequency into a corresponding high frequency electrical energy in this diagram to 20000 Hz.
All thermoplastic materials except PTFE can be welded.
Ultrasonic welding is a widely recognized and accepted process for joining thermoplastic materials. Discover our ESW ultrasonic press. When applied to metals a notable characteristic of this method is that. Ultrasonic Welding is a plastics welding process in which two work pieces are bonded as a result of a pressure exerted to the welded parts combined with application of high frequency acoustic vibration ultrasonic.
