Based on the past experience, it is found that there are some quality problems that are easy to occur: scars or cracks on the product surface, distortion, deformation or self color of the product, damage or extrusion of internal parts of the product, displacement and deformation, product burr, the size of the product after welding cannot be controlled and within the tolerance, product dislocation, and the water and gas sealing performance requirements cannot be met after ultrasonic welding.
Generally speaking, the factors affecting the ultrasonic welding effect are concentrated in the following aspects:
1. Amorphous polymer thermoplastic is an ideal material for ultrasonic welding.
2. 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.
3. The common quality problems of ultrasonic welding in production can be solved by optimizi…
