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
what's the characteristics of piezoelectric ceramic material Judging whether piezoelectric ceramic materials are suitable for surface acoustic wave devices can be considered in the following aspects: (1) The dielectric constant should be moderate. Generally, the dielectric constant is required
How to choose right ultrasonic transducerAn ultrasonic transducer is an energy conversion device whose function is to convert the input electrical power into mechanical power (ie, ultrasonic waves) and then pass it out, while it consumes a small amount of power (less than 10%). Therefore, the proble
Common plastic variety identification method Polypropylene PP is easy to melt and drip, less yellow smoke on the yellow, continue to burn oil Polyethylene PE is easy to melt and drip, and yellow and blue continue to burn paraffin burning smell PVC is difficult to soften, yellow, green, smok
