Ultrasonic welding machine because of the expensive price of equipment, a machine often needs to weld different plastic products, so different moulds need to be replaced to achieve a multi-purpose machine, and the replaced moulds can not be placed freely, it is best to maintain properly and extend t

Ultrasonic generator (or power supply) is a device used to generate and provide ultrasonic energy to the ultrasonic transducer to work at the resonant frequency. According to its excitation mode, it can be divided into two types: one is his excitation mode, the other is self-excitation mode. The o

The two most widely used reflectors for bicycles are circular and strip-shaped. The plastic material is PC and PMMA. After the injection parts are assembled, the assembly process is completed by ultrasonic welding machine. They are mainly mounted on the side or front shock absorber of bicycles. The

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

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

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

Ultrasonic welding is normally divided into two modes: time mode and energy mode.Time mode of ultrasonic weldingThere are several control modes for welding equipment operation. The simplest and most common mode is the time mode, ie the ultrasonic energy acts for a predetermined time without regard t

Ultrasonic probe ultrasonic flaw detection principle and sensor test and designUltrasonic transducers, horn and vocal sleeves are devices that convert electrical energy into vibration. To understand the principle of operation, a comparison can be made between an ultrasonic welder and a car.The
