Pet Plastic Bottle Blow Moulding Process

PET plastic injection molding process is one of the very important technology for processing plastic, PET plastic bottles, most of the plastic packaging plant will adopt blow molding production process, but the injection molding process has especially the unique processing advantages.

Blow molding is a two part plastic manufacturing process. The first part of this plastic manufacturing technique starts by creating starting tubes of molten plastic, called Parisons. These are needed as the base for the extrusion blow molding process, regardless of the type of plastic bottle, container or part that is being created.

In the two-stage process, preforms are injection molded, stored for a short period of time (typically 1 to 4 days), and blown into containers using a reheat-blow (RHB) machine. There are two major reasons for stretching PET. The first is purely economic. Stretching allows thinner, more uniform sidewalls and thus less expensive containers.

To make these prefroms, a perform manufacturing machine that took a continuously extruded PET tube, heated and closed one end, and then heated the other and formed a thread finish by blow moulding. This process had a faster output rate, at 12000 preforms per hour, than the early injection moulding routes of 8 and 16 cavity moulds.

In 1941, PET was developed by chemists at DuPont, but it took until the 1970s for the plastic bottle to be popularized. An engineer for the DuPont Corporation, Nathaniel C. Wyeth, developed the first plastic bottle after years of experimenting. He discovered the blow-molding method still in use today. Wyeth conquered long-running problems — such as uneven wall thickness and irregular neck sizes — with blow-molding …
