1: The drop temperature is relatively important. There are many problems with poor temperature control, including the influence of material type and molding.
2: Mold temperature: including the influence from the design of the mold, the material. In fact, when the glass bottle forming auxiliary equipment is relatively good, the mold temperature is relatively easy to control.
3: The extension is the initial mold opening, to the mold closing, when the positive blowing starts.
4: Coordination of actions. Including coordination due to machine speed and machine offset.
5: mold design: including mold heat dissipation, mold matching, mold extension ratio
