A PET Preform Strain Viewer is a specialized equipment designed to assess the common defects within transparent PET (Polyethylene Terephthalate) preforms. This device operates based on the principle of polarized light. When polarized light passes through a stressed material, it experiences changes in its polarization state, which can be visualized and analyzed.
It is widely used in the quality control and quality management of PET rough processing products, which is convenient for users to timely and effectively control the product stress and help to ensure and improve the product quality.
