1: Gob temperature, this is relatively important. If the temperature is not well controlled, there will be many problems, including affecting the material shape and molding.
2: Mold temperature: including the influence from the design of the mold, material. In fact, in the case of modern auxiliary equipment for glass bottle forming, it is relatively easy to control the temperature of the mold.
3: Extending (some people call it reheating) means that the initial mold is opened, and when the finished mold is closed, the air blowing starts.
4: Coordination of movements. Includes coordination due to machine speed and machine offset.
5: Mold design: including mold heat dissipation, mold matching, mold extension ratio
