1. Different process. The blown glass bottle is first drawn into a glass tube, and then the glass tube is used to make the bottle on a vertical turntable machine. The molded bottle is produced using boron (B) sand and quartz sand on a kiln line machine (Produce ) To make the bottle, the control bottle does not use a mold (title: mother of industry), only two sets of mold wheels are used, and a complete set of molds is required to mold the bottle.
