An Overview About The Process Of Ultrasonic Welding

Posted by Admin on September, 27, 2019

Well, the technique of ultrasonic welding can be described as an industrial process which makes use of acoustic ultrasonic vibrations of high frequency for holding the pieces of work together and create a solid weld.

This type of welding is used for materials like plastics and metals, to join dissimilar materials. In this process, no connective instruments like bolts, adhesives, soldering materials, nails, etc. are used for binding materials together.

When this welding process is applied in case of the metals, a notable exception is observed. For ultrasonic plastic welding, the temperature is kept steady below the marking point of the metals and components which are involved.

This is done to prevent the interference of unwanted properties of the material, which may or may not arise when the material is exposed to high temperature. So, the temperature is maintained by the welders, which is strictly followed.

Process of Ultrasonic Plastic Welding

  • To join the complex thermoplastic parts, which are injection moulded, a high-quality welding machine is used. The equipment is customized by the user to fit the required specifications of the parts which are to be welded.
  • The welding parts neatly help back in a sandwich position between the anvil, or the fixed best and the horn or the Sonotrode. The Sonotrode is connected directly to a transducer, emitting acoustic vibrations of low amplitude.
  • When plastic scraps are to be welded, the junction point of the two parts is carefully designed to focus on the melting process. One side of the material used owns a spiked or round-shaped energy director which connects with the second end.
  • With the help of the ultrasonic energy, the point of contact between the parts slowly melts, which creates a joint. The process of ultrasonic welding is considered over gluing, screwing or snap fitting because when a material melts and joins itself, it is stronger and long-lasting.

Applications of Ultrasonic Plastic Welding

Well, typically, machines are required from the ultrasonic plastic welding machine exporter for working with small parts of cell phones, medical tools, toys, etc. These machines are also used in working over large automotive clusters of the instrument too. The process of ultrasonic welding is carried out for welding the metals but is strictly limited to welding thin and malleable metals like aluminum, nickel, only. The process cannot be used for welding chassis of an automobile or for joining pieces of bicycle because of the difference in the power levels.

In the ultrasonic process welding of thermoplastic material, local melting of plastic is observed. It occurs due to the absorption of the vibrational energy m at the joint, which will be welded.

When welding is undertaken in case of metals, the process takes place under high-pressure dispersion of the oxides and the local property of the material. In some cases, it is even seen that the heating process is not strong enough to melt the metal base material.

Where Can Ultrasonic Welding Be Used?

This welding process can be used in case of hard and soft plastics and even metals. The practise of ultrasonic welding has gained a wider prospect with extensive research and tests. More sophisticated and inexpensive machines are manufactured and sold by ultrasonic plastic welding machine exporters to meet the increased demand of the welding units for electronic as well as plastic components.

Benefits of Ultrasonic Welding

Coming to the benefits of the process of ultrasonic welding, it can be described as a fast and more conventional over the use of adhesives and solvents. The welded material gets dried up fast and has stronger joints. Using these high-quality machines, the entire process of welding can be easily automated with the creation of clean and precise joints.
