Test Strains Present In PET & Preforms With Polariscope Strain

  • click to rate

    PET is a commonly used material for the manufacturing of plastic bottles and containers. PET preform defects testing is a critical step in the production process as it ensures the quality and safety of the final product. When these products will be manufactured, then defects like cracks, stress, and strains will be seen in them. PET preform defects testing is crucial in ensuring the quality and safety of plastic bottles and containers. Thus, we at Presto have designed a high-quality lab testing instrument known as Polariscope strain viewer-NXG.

    This is one of the high-quality lab testing instruments that helps the manufacturer in testing the quality and transparency of PET preform bottle. It is based on the principle that any change in refractive index is due to different strain distributions and this leads to lower transparency of the material. In this blog, we will discuss a brief about the Presto Polariscope strain viewer and how this laboratory testing equipment is used to test different properties of the materials and ensure that quality products will be delivered to the customers.

    Introduction to the Polariscope Strain Viewer-NXG

    The Polariscope is a powerful testing instrument for understanding PET & preform test strains. Preform test strain is the amount of deformation a material experiences during testing. This testing instrument can easily be used to analyze the birefringence and optical properties of transparent materials. It is widely used in industries such as manufacturing, and engineering to detect and visualize internal stresses and strains in PET & Preforms.

    The NXG model features a high-resolution LCD display, polarizer and analyzer filters, and a powerful LED light source that helps to highlight and magnify the internal strains and stresses in the material being examined. By using this quality laboratory testing equipment, manufacturers can test the defects present in preforms.

    With its user-friendly interface, the Polariscope strain viewer NXG is easy to operate, and it can be used to test a wide range of materials. Users will get a sharper and clear optical viewing experience while testing the products with the help of this testing instrument.

    Now, let us discuss briefly the features and technical specifications of this quality testing equipment.
