Automatic Welding Box of Lighter 

Generally speaking, the factors affecting the ultrasonic welding effect are concentrated in the following aspects: Amorphous polymer thermoplastic is an ideal material for ultrasonic welding. According to the product characteristics and occasions, ultrasonic welding lines generally adopt four modes: triangular welding line, peripheral welding line, peak valley welding line and step welding line. The common quality problems of ultrasonic welding in production can be solved by optimizing and improving ultrasonic welding fixture, adjusting ultrasonic welding conditions and optimizing ultrasonic welding line. Ultrasonic welding is mainly used for the secondary connection of injection molded parts and the assembly of plastic parts (such as power adapter and the connection of upper and lower plastic shells). Therefore, special attention is paid to the plastic welding quality and product aesthetics, and the quality is still difficult to control. To control the weldi…
