![]() ![]() This is followed by a region of continued stretching, where the amount of force remains constant (C). If stretching continues past the yield point (B), however, the material will start to stretch and become thinner, causing permanent deformation. Here PET behaves somewhat like an elastic material: if it is stretched only a small amount and released, it will shrink back to its original size. As force is applied to the material, there is a region where very little stretching occurs (A). Orientation is a physical alignment of the polymer chains in a regular configuration.Ī typical stretching sequence for PET is shown in Figure 1. Second, with the stretching comes orientation and a dramatic improvement in physical and barrier properties. Stretching allows thinner, more uniform sidewalls and thus less expensive containers. There are two major reasons for stretching PET. 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. In the one-stage process, preforms are injection molded, conditioned to the proper temperature, and blown into containers-all in one continuous process. There are two distinct stretch blow molding techniques. Biaxial orientation provides enhanced physical properties, clarity, and gas barrier properties, which are all important in products such as bottles for carbonated beverages. ![]() Please visit our page or contact us at if you are looking for a cleaner bottle preform mold manufacturer.This process involves the production of hollow objects, such as bottles, having biaxial molecular orientation.

We offer a wide range of services at Go4mould Additionally, this element can be made lighter and customized, further improving the container’s quality and characteristics. It is important to not underestimate the importance of bottleneck design. To make production more efficient, Go4mould studies the customer’s needs carefully. Reduced bottle thickness leads to material savings and, obviously, to lighter finished containers, but it is always important to consider the strength of the bottle and how it will be shaped. The preform design of the cleaner bottle is fundamental since it determines the number of factors that characterize the bottle: In the chemical processing industry, preform molds for cleaner bottles are commonly used.įigure 1: Cleaner bottle preform mold Cleaner bottle preform mold: Designing Depending on the requirements of the customer, we can produce any kind of preform.
