We have innovatively simplified the production method of cup-shaped masks, optimized from the original complex manual or semi-automatic mode to fully automatic, and innovatively launched a two-stage production method, that is, the automatic pre-process of cup-shaped masks + fully automatic post-process of cup-shaped masks, the front process is responsible for the molding and melting of cup-shaped masks, and the fastest speed can reach 40 per minute. The post-process is responsible for welding the headband, punching the welding valve, and outputting the finished product. It can greatly reduce the input cost, and can also be linked to other brands of post-process production lines to achieve fully automated production, whether it is an adjustable headband, or a headband nailing, or ultrasonic welding headband, we have a very mature technology.
