We use injection-stretch-blow molding (ISBM) machine to make the PET bottles. The process is also called "1-Step", here're some key features different from the products made by 2-Step:
We could make bottles with the same orientation of screw, which could make the closures (screw cap, flip caps, pump, etc.) pointing in the same direction.
"One-Step" ISBM method is also called "Hot Preform", because the preform remain warm during the process, which could present a better shaping ability, a sharper angle.
In case of 2-Step process, It's necessary to make color preform in advance, there're two problems: 1. the color would be different from preform to bottle. 2. the MOQ would be huge. In 1-Step ISBM process, the color is more adjustable and the MOQ is reasonable.
