The Polariscope Strain Viewer, provided by Pacorr, stands out as a critical instrument for ensuring the highest quality standards in PET container production. This device utilizes polarized light to reveal stress and strain defects that could compromise container integrity and performance.

Understanding the Polariscope Strain Viewer
The Polariscope Strain Viewer employs two primary light sources: Monochromatic CFL and Sodium Light. These lights, when passed through PET preforms, reveal the presence of stress and strain by reflecting or refracting in patterns that are visible to the observer. This method allows for the early detection of potential defects, ensuring that only the highest quality preforms proceed to the bottle-making stage.

Key Features and Specifications

• Model Name: PSP-1
• Power Requirement: 220V, Single phase, 50 Hz
• Light Sources: CFL Light & Sodium Light

This device offers sharp, clear optical viewing experiences and accommodates preforms of various shapes, enabling precise defect detection.

Application in Industries
The Polariscope is versatile, supporting quality assurance in the production of glass, PET preforms, and even gemstones. Its ability to detect structural anomalies in materials makes it invaluable across various sectors, including packaging, glass manufacturing, and gemology.

Advantages of Using Polariscope Strain Viewer

Quality Control
It is instrumental in identifying imperfections at an early stage, thus preventing costly production errors and ensuring that the final product meets industry standards.

Cost Savings
By detecting defects early, it reduces waste and avoids the expenses associated with producing substandard products.

Brand Reputation
Using such advanced quality control instruments helps maintain a brand's reputation for reliability and quality, essential for customer trust and loyalty.

Pacorr: A Commitment to Excellence
Pacorr's dedication to quality is evident in its wide array of testing instruments, designed to meet international standards. The Polariscope Strain Viewer is a testament to their commitment to innovation, precision, and customer satisfaction, as evidenced by their extensive global clientele, including major brands across various industries.

The Polariscope Strain Viewer from Pacorr represents a significant advancement in quality control technology for the PET container and glass industries. By providing precise, reliable data on material stress and strain, it plays a crucial role in ensuring the durability and safety of packaged products. As the demand for high-quality packaging continues to grow, tools like the Polariscope are essential for manufacturers committed to excellence and customer satisfaction.

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.

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.
