Product Description

Description:

The core spare parts of mask machines are various, including ultrasonic welding system, rollers of different sizes and different usages, such as folding rollers and normal rollers and rollers that are used to smooth the mask film. They also include different kinds of mask mould and different kinds of the blade for mask tape cutting. To put it more briefly, I will mainly discuss the ultrasonic welding system in the spare parts of mask machines, since they are the most common parts and the core spare parts that are purchased by manufacturers. The principle of multi-layer fusion of non-woven fabrics is to use the high frequency friction between the contact surfaces to rapidly generate heat between molecules. Under a certain pressure, multi-layer non-woven fabrics can be fused together. The frequency of 20kHz and 15kHz are commonly used for welding of non-woven fabrics.Ultrasonic energy penetrates the material so that it is fused together. Generally, tooth, mesh and strip-like lines are made on the welding head to form a pattern on the surface of the fused product, and to fuse multiple layers of cloth together.Disposable flat masks and N95 masks are made in this way.
