What is the working process of an ultrasonic plastic welding machine?

An ultrasonic plastic welding machine is a kind of machine that adopts ultrasonic welding technology, which is a very mild joining technology for processing thermoplastic materials and non-ferrous metals. In the plastic processing industry, the ultrasonic plastic welding machine has many uses. Depending on the size and geometry of the components, different numbers of ultrasonic electrodes can be used to weld these components. Usually, a reliable ultrasonic plastic welding machine can support a constant workflow of producing high-quality plastic products. So, what exactly is the working process of an ultrasonic plastic welding machine? Please let me introduce this to you in the following contents.

What is the key function of an ultrasonic plastic welding machine?

The main function of an ultrasonic plastic welding machine is not difficult for everyone to know, because the name of this machine already tells us a lot. Generally speaking, ultrasonic plastic machines have various assembly options, such as spot welding, continuous welding, hot riveting, riveting, inserting, etc. This machine mainly converts electrical energy into mechanical energy, which is ultrasonic, and then uses it to melt the plastic materials in a very gentle way and then weld it properly, thus reducing the whole production process of the ultrasonic plastic welding machine. The whole working cycle of this machine is very fast which makes it is an excellent choice for industrial production.

How many components of an ultrasonic plastic welding machine are there?

Typically speaking, there are five components of an ultrasonic plastic welding machine, namely, the press, the generator, the transducer, the booster and the sonotrode. The press is needed to have a low friction sliding mechanism and are needed to be able to withstand a capacity of 50 to 3000N. Also, it is should have an accurate stroke adjustment, an adjustable mechanical stop, high-precision pressure regulation and speed control. The generator are ought to have a uniform amplitude at all power levels, and accurate frequency control and fine overload protection. A reliable transducer is required to be made up of high-quality sintered ceramic PZT materials. The design of the sonotrode is dependent on a number of factors including amplitude, gain required Frequency, Material to be welded, Sonotrode material, Profile or form of component.

What is the working process of an ultrasonic plastic welding machine?

The working process of an ultrasonic welding machine is not hard to understand. The press in an ultrasonic plastic welding machine provides the necessary forces that must be applied during the welding process. In any ultrasonic welding application, the application of controlled force is critical because the power drawn from the generator is directly affected by the applied pressure. Therefore, the press must provide a solid mounting and precisely applied downforce. With very few exceptions, all ultrasonic plastic welding presses are pneumatically operated and the fact that the cylinder provides an exponential increase in pressure is usually beneficial to the welding process. The generator powers the welding operation and is therefore a key feature of the machine. It must be able to provide a very consistent output amplitude and be able to resist overload. The sensor converts the applied vibration electrical signal into mechanical vibration. This is achieved by using a sintered ceramic PZT material, which changes thickness when polarization is applied. The booster transfers energy from the converter to the ultrasonic generator. And the ultrasonic generator transfers the welding energy directly to the parts to be welded.
