I. OverviewPPS (polyphenylene sulfide) is a semi-crystalline thermoplastic with a steep melting curve and a high melting temperature (285 ° C, 545 ° F), and its pure PPS is not suitable for ultrasonic welding. However, after the addition of glass fiber and other fillers, the rigidity of the PPS mixt

图片1 To solve the welding quality problem, it is not only necessary to use the DOE test method to optimize the parameters, but more importantly, to grasp the two key factors affecting welding - heat and pressure.In order to facilitate everyone's understanding, I take hot plate welding as an example h

Ultrasonic welding technology is not a new concept and is more reliable than adhesives. But if you want to combine two completely different materials, such as only with plastic, the ultrasonic welding process is very difficult.If the metal material has to be replaced with a plastic material due to t

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
