Ultrasonic welding can be explained as high frequency vibration waves for an ultrasound of the piece to be welded. The pieces come together under high level of pressure, which results in the resistance of the weld. Plastics are the pieces that are normally used in this type of welding.
An interesting fact is that ultrasonic welding works best with similar or identical material layers. The welding of different plastics is possible by both methods, but requires special equipment and/or process adjustments to be successful.
The ultrasonic vibrations allow the welder to weld the materials together without having to use bolts and nails or other materials to join the pieces together. The vibrations are applied to thermoplastics as they melt, and the vibration is like a magnet that contracts the parts to push them.
An ultrasonic welding machine is used for various types of materials; one of the main materials in which it is used is metal. For metal, the welding process is known as friction welding of the work piece. A welding sonotrode is a type of horn from which weld vibrations emanate. The sonotrode softens the plastic so that the plastic becomes thermoplastic and can be joined. Any type of material used for welding has a different resistance. Metal has the strongest bond and this is because it is welded with ultrasonic waves.
Ultrasonic welding machines from Huizhou Shengyang Industrial Co. Ltd. are fast, clean and energy efficient. They produce strong and durable bonds that are as strong or even stronger than the starting materials. It does not need adhesives, solvents, or other additives.
Ultrasonic welding can be used when several jobs must be performed. This form of welding will make work faster and is a very successful method. In the automotive and electronics industries, this method is often used to weld your products because it requires a lot of inventory to be employed. Metals, hard plastics and soft plastics are all materials that can be used with the ultrasonic welding process. Since ultrasonic welding of the above materials is so successful today, it is currently investigating how well it works with other types of materials. Ultrasound was in great demand for other products, so it should be explored. For example, there are some underwater welding schools where everything is explained in detail.
In order for ultrasonic welding machines to work perfectly, two materials must be able to be connected to each other at high pressure. An anvil is used to position the parts where they should go, so that they can adhere to them to bond. The sonotrode horn also requires an ultrasound stack to adjust it to the correct vibration state. Next, a high-power AC ultrasonic generator is needed to adjust the stacking resonance. A controller is also required to maintain the movement of the press and the way it provides the ultrasound energy. In the future, you can expect ultrasound energy to be used for several other bonding projects, as it is very popular among many manufacturing companies.
