Portable ultrasonic car noise board spot welding machine welding principle The 900W ultrasonic plastic spot welding machine converts 28KHZ high-frequency electric energy into mechanical vibration energy by ultrasonic transducer, and then transmits it to the welding head through the variable ampli

Common defects and Solution of ultrasonic weldingFirst, the strength can not reach the desired standard.Of course, we must understand that the strength of the ultrasonic welding operation can never reach the strength of integral molding. It can only be said that it is close to the strength of integr

When we using our transducers, there are some reflections of aluminum cracking of the transducer or horn from time to time. Moreover, in the failure of aluminum cracking of the transducer, there is another phenomenon that is worthy of attention. The failure of the aluminum cracking of the transducer

The ultrasonic welding process of the product needs to meet three basic conditions to achieve the desired effect.1. Whether the two plastic materials can be welded: Some materials can be welded better, some are basically melted, and some are not melted. The melting point between the same material is

Piezoelectric ceramic sheet quality is the main factor determining the life of the transducer. The transducer is cracked during assembly, and the piezoelectric ceramic itself has problems, such as internal delamination, and the mechanical part of the vibrator is too far from the expected value. The

The amplitude is a key parameter for the material to be welded, which is equivalent to the temperature of ferrochrome. If the temperature is too low, it will not be welded. If the temperature is too high, the raw material will burn or cause structural damage and strength. Because each transducer is

Frequency has nothing to do with amplitude.The number of full vibrations completed by the vibrating mass in one second is called the frequency of the vibration, and its unit is Hertz (Hz). The frequency is also the physical quantity indicating how fast the particle vibrates. The higher the frequency

Ultrasonic welding is unevenly stressed and weldedWhen the ultrasonic works, the contact between the product and the surface of the mold can get the desired welding effect. In fact, this is only the surface view. Since the ultrasonic vibration is frictional vibration, the sound wave transmission phe

Ultrasonic transducer principle and ultrasonic mold matching 1. Ultrasonic transducer principle and design (ultrasonic vibration system) matchingAbstract: The design and calculation of the ultrasonic transducer system of plastic welding machine, and the use of PRO-E three-dimensional software to dra

How to make ultrasonic horn? First, let's understand the properties of ultrasonic welding horn:Welding requirements of the product: According to the welding requirements of the product, the service life of the ultrasonic mold is analyzed, and then the aluminum alloy or titanium alloy is used to make
