Welding ear loops of disposable masks such as flat masks, KN95 masks, N95 masks, medical masks or non-medical masks can quickly and effectively increase the production capacity of masks. At present, there is no relevant authoritative organization to evaluate and rank all ultrasonic mask spot welding machines on the market. Because the production process, design, technology and accessory brands of ultrasonic mask ear loop spot welding machines are different from each manufacturer, the quality of ultrasonic mask ear loop spot welding machines is also different. There are often problems such as weak welding, and the after-sales service is also different.
