Process flow of High Speed Blow Molding Machine products
The blow molding process of High Speed Blow Molding Machine products is a two-way stretching process, in which the PET chains are bidirectionally extended, oriented and aligned, which increases the mechanical properties of the bottle wall and improves the tensile, tensile, and anti- Impact strength and good air tightness. Although stretching helps to improve the strength, it should not be stretched too much. The stretch-to-expansion ratio should be controlled: the radial direction should not exceed 3.5-4.2, and the axial direction should not exceed 2.8-3.1. The wall thickness of the preform should not exceed 4.5mm.

The blowing of High Speed Blow Molding Machine products is carried out between the glass transition temperature and the crystallization temperature, generally controlled between 90 and 120 degrees. In this range, PET exhibits a high elastic state, and becomes a transparent bottle after rapid blow molding, cooling and setting. In one-step method, this temperature is determined by the length of cooling time in the injection molding process (such as Aoki blow molding machine), so the relationship between the injection and blowing stations must be well connected.
