Generally speaking, an Wholesale Ultrasonic Plastic Welding Machine Factory is a component that conducts high frequency sound vibrations to a plastic processing part. The amplitude of the movement is measured in microns, and is usually between 15 and 35 kHz.
The device is comprised of a metal plate or ceramic disc as an electrode. When an electrical signal is passed to the transducer, it expands and creates a high frequency vibration. The resonance impedance of the device is relatively low, and its electromechanical conversion efficiency is good.
When the transducer is paired with a booster, it can increase the ultrasound vibration intensity. The booster provides the connection between the transducer and the welding press. The booster is usually half the wave length of the ultrasound.
Booster for Ultrasonic plastic welding machine - Booster is an important part of the welding stack. It serves two functions. First, it acts as an amplifier for input vibration. Second, it provides a location for mounting the welding press.
Booster is usually made from Titanium alloy to provide smooth vibration. It is a better choice than steel alloy or aluminum alloy.
The converter is a mechanical device that converts electrical energy into vibration. It has three mass parts that are clamped together by a center bracing bolt. They will expand and contract with the application of electrical signals.
Typical output frequency ranges from 15 to 40 kHz. This frequency is suitable for most applications, but it may be too aggressive for delicate or smaller parts. Higher-frequency equipment produces lower amplitudes.
Getting the right amount of power is important for welding. China Ultrasonic Plastic Welding machine Wholesale is an advanced technology that uses vibrational energy. It is used to weld a variety of thermoplastics. Depending on the material, the power requirements for the ultrasonic welding machine can increase exponentially.
Ultrasonic welding machines are powered by a converter, which transforms a low frequency electric current into a high frequency sound wave. The converter then connects to a booster, which increases the strength of the ultrasound vibration. This power is then delivered to the weld horn, which functions as a resonating tool. The ultrasonic vibration is transmitted through the work piece, and the frictional heat carried by the conduction process melts the surface asperities.
The amplitude of the sound wave is also important for the welding process. A higher amplitude may initiate melting and initiate the weld process, but it can also be harmful to the material.
Using ultrasonic welding to join molded plastic parts is a good idea. This is because the technique produces clean, seamless joints. It also allows for increased flexibility and versatility. But there are some limits to the process.
First, the material used in the process needs to melt within a temperature range of 400F. This is a challenge for thick materials. If the material does not melt, it can be damaged during the weld. Another limitation is that the ultrasonic welding machine will only weld lap joints.
There are several types of ultrasonic welders. The one you choose depends on your budget and capabilities. Some manufacturers offer weld data for thermoplastics, but the best way to find the right machine is to try a few.
