Why is filter cartridge filter cotton easy to wrap around the mouth

During the ultrasonic molding process, filter cotton often bursts due to two main reasons: firstly, there are problems with the raw material formula, and suppliers lacking technical and customization experience cannot produce filter cotton materials that meet the requirements. Different melting points and ratios can easily cause problems such as weak adhesion and bursting during the heating process, and uneven thickness and looseness in local areas. The second is the setting of equipment molding temperature. Different weight and thickness of filter cotton correspond to different molding temperatures. Before mass production, it is necessary to test and adjust the temperature. At the same time, suppliers are also required to provide stable quality filter cotton for mass production.
