1: Mold temperature: including the influence from the design of the mold, material. Glass wine bottles are actually relatively easy to control when the molding equipment is better.
2: The temperature of the gob, this relative is important. There are more problems with this temperature, including affecting the material type and molding.
3: Coordination of actions. Includes coordination due to machine speed and machine offset.
4: Mold design: including mold heat dissipation, mold matching, mold extension ratio.
5: Extension (some people call it heavy), that is, the initial mold is opened, and the mold is closed, and the air is blowing.
