Pacorr - Model PSP-1 -Polariscope Strain Viewer

PET containers have been the first choice in the packaging industry due to their sturdy built and durability. Moreover, while producing, PET material provides an ample amount of flexibility and at the same time ensure the strength quality. With so many benefits PET containers and bottles are in use in almost all industries. However, such high-demand products are required to be tough and stable at all conditions.

To produce any PET containers, the manufacturer first produces its preform by blowing method. These preforms are tested for many aspects before they are transformed into bottles. One such quality defect in the development of stress & strain. During the production of preforms, due to inappropriate blowing methods, the preforms may develop stress marks, uneven surfaces, bubbles or strains on them. These defects can vary in shape and size and many not are visible by naked eyes. Doesn`t Matter how small, but these strain defects can lead to major defects in future. The bottle shape may not be as per requirement, they may not be stable, they may be too weak to store a few substances etc.

It is vital to test these preform before so that we get the faults and quality issues detected at the primary level and can save the errors to flow in the production line and saving a lot of costs. Also, if passed to the bottle stage, there are a few strains that can be unnoticed and undetected but can compromise the quality.

Polariscope strain Viewer helps the user to view all kinds of stress or strain acquired by any preform. It is equipped with two standard-based lights, Monochromatic CFL Light and Sodium Light. These lights when passed through the sample preform, will either reflect or refract. Based upon their transparency and quality the lights will develop a pattern. This pattern can be viewed by the user and compared with the preform defect chart (available with the equipment). The pattern viewed when seen in the defect chart will define the quality standard of the specimen. The equipment provides a large viewing area that is suitable for distinct sized preforms. Accordingly, the user knows in advance whether the preform will sustain as a bottle or not.

This practice can save a lot of time, energy and cost of production with a low-quality preform. Also, if not tested at right time and with precise equipment, it can lead to poor brand reputation among customers.
