The ultrasonic plastic welding process

Ultrasonic waves used in plastic processing, the existing several operating frequencies are 15KHZ, 20KHZ, 30KHZ, 40KHZ. Its principle is to use the longitudinal wave peak position to transfer amplitude to the gap of plastic parts, under pressure, so that two plastic parts or other parts and plastic parts of the contact part of the molecular collision to produce melting, so that the contact plastic fusion, to achieve the purpose of the welding process.

Which kind of plastic ultrasonic welding effect is good?

Amorphous polymer (ABS, PC, PS, PVC, PMMA, etc.): the molecular arrangement is disordered, there is an obvious material gradually soft, melting, and flow temperature. Such resins are generally effective at transmitting supersonic vibrations and achieving good welding over a fairly wide range of pressures/amplitudes.

Crystalline polymer (PE, PP, POM, PA6, PA66, PBT, PET, etc.): the molecular arrangement is orderly, with an obvious melting point and refreezing point. Solid crystalline polymers are elastic and can absorb some of the high-frequency mechanical vibrations. Therefore, such polymers are not easy to transmit ultrasonic energy to the bonding surface, which requires a higher amplitude. High energy is required to break the semi-crystalline structure and make the material change from the crystalline state to the viscous state, which also determines the obvious melting point of this kind of material. Once the molten material leaves the heat source, the temperature will decrease to a certain extent, which will lead to the rapid solidification of the material.

Secondly, generally speaking, non-polar compounds (such as PP and PE) are more difficult to be ultrasonic (not impossible) welded, polar compounds can be ultrasonic welded, and between polar compounds can also be ultrasonic welded, such as ABS and PMMA can be ultrasonically welded.

Incorporated in 2015, K& M Technologies Ltd is one-stop solution provider in plastic welding business, especially in ultrasonic plastic welding, ultrasonic non-woven fabric sealing and cutting, hot plate welding, water filter welding lines...

From June 2021, We started the cooperation with a famous brand Dongho Ultrasonics, and co-established a new company Sincere Sonics to handle the overseas market of Dongho brands ultrasonic welding machines.

We have the professional team for the design of the equipment based on over 25 years' experience of the main staff in this industry.

We have sold to more than 100 countries in the world in the past years, including coutries from Asia, Europe, South America, North America, Oceania and Africa.

Our product series include QD series, ME series, SS series and Dongho Series for ultrasonic welding machines; AY series for filter welding machines and hot plate welding machines.

Now we have agents in Turkey, India, Ukrane, Maylasia, Vietnam and we are looking for more agents or distributors around the world who can take good care of the aftersales services in the country or territory.
