2. How Injection Stretch Blow Molding Machine Work?<\/h2>\n

The efficiency of the injection stretch blow molding process<\/strong> lies in its 4-station circular architecture. Station 1 handles high-precision injection molding of the preform, utilizing a 50mm screw diameter designed for optimal melt homogeneity. Station 2 is dedicated to heating, preform tail cutting, and pre-blowing conditioning, which is essential for uniform wall thickness distribution. Station 3 is the critical injection stretch molding<\/strong> phase, where the preform is biaxially stretched and blown into its final shape using high-pressure air. Finally, Station 4 facilitates the automated take-out of the finished product. This continuous flow prevents the preform from cooling down completely, saving significant energy compared to reheat systems. For those looking for a replacement of ASB and Aoki<\/strong> equipment, the EP-BPET-125-V4 offers a more modern, cost-effective alternative with superior servo-driven control and user-friendly interfaces, making it the preferred one-step injection stretch blow molding machine<\/strong> for modern factories.<\/p>\n<\/div>\n
