Product descriptions from the supplier
Description:
Mask production equipment relies on a diverse range of essential components, such as the ultrasonic welding unit, various rollers serving distinct functions—like folding, standard handling, and film smoothing—along with different mask molds and cutting blades designed for tape separation. To streamline the discussion, I’ll focus on the ultrasonic welding system, as it stands out as both the most frequently replaced and a central component in procurement. This system works by applying high-frequency vibration between two surfaces, creating intense molecular friction that quickly produces heat. With consistent pressure applied, multiple layers of non-woven material bond seamlessly. Frequencies of 20kHz and 15kHz are standard in this process. The ultrasonic waves pass through the material, enabling fusion. The welding head typically features toothed, meshed, or ribbed patterns to create visible markings on the final product and to join several fabric layers. This method is widely used in manufacturing disposable face masks and N95 respirators.
