Ultrasonic welding technology of automobile plastic parts
The lightweight requirements of automobiles have made plastic products widely used in the automotive industry.
In order to better meet the requirements of plastic welded parts for weld strength and appearance quality, while ensuring product production efficiency, we chose the commonly used plastic PP for automobiles to conduct welding tests. The influence of ultrasonic welding process parameters on weld strength and appearance quality.
The results show that under a certain holding time and welding pressure, the welding depth plays a decisive role in the weld strength and appearance quality of automotive plastic parts. When the welding pressure is 0.2 MPa, the holding time is 2.0 s, and the welding depth is 1.8 mm, it can not only ensure the weld strength of automotive plastic parts, but also meet the requirements of appearance quality. This result has certain guiding significance for products that also use PP materials and are prepared by ultrasonic welding.
