1: Drop temperature, which is relatively important. There are many problems with this temperature, including affecting the material type, forming, etc.
2: Mold temperature: including the influence from the beginning of mold design, material. In fact, in the case of modern glass bottle forming auxiliary equipment are better, mold temperature control is relatively easy.
3: Extension (some people call heavy heat) that is, the opening of the initial mold, to the closing of the mold, when the positive blowing begins.
4: Coordination of actions. It includes the coordination of machine speed and machine bias.
5: Mold design: including mold cooling, mold matching, mold extension ratio.
