Polariscope Strain Viewer
2 Per Piece
1 Piece (MOQ)
Polariscope is used to view the internal material stresses and material flow characteristics of PET preforms and containers. This is ideal for laboratory use and at-the-line preform and bottle inspection Defects in preform can be easily detected by using this equipment. When a preform is held parallel to viewing field colour pattern is seen known as isochromatic fringe. This indicates magnitude of the stresses introduced during moulding process. When a preform is held 45 deg to viewing field a coloured pattern known as isoclinic is seen, this indicates direction of stresses. ‘TBG’ Polariscope is used in the preform assembly to check the possible defect in the preforms. Take the precautions at the early stage would help a lot in cost cutting and time-saving. A defect chart is provided to understand these defects. FEATURES The devices gives you 2 slots for different light orientation; one is for 90° and other is for 45° The weight and sizes of the device are according to models The devices requires the standard power supply i.e. 220/240V

Presto offers Polariscope, a highly efficient strain viewer that helps the manufacturers in testing the quality and transparency of the products so that best quality assurance could be ensured to the customers. The working of the Presto’s Polariscope is based on the principle that any change in refractive index is due to different strain distribution and this leads to lower transparency of the material. The testing instrument offered by Polariscope comes in variety of sizes and specifications according to the requirements of the clients Photoelasticity is a major phenomenon that occurs in PET, Preforms and Glass products. Photoelasticty means the change in the refractive index of the material when there is non-uniform strain distribution throughout the material. Photoelasticity can be a great problem for the manufacturers of PET and glass products as this is great flaw in the quality of the products. Presto offers two models of Polariscope that are Polariscope Dx and Polariscope computerized. The instruments are manufactured with best quality of materials to provide an extended service life and accurate testing procedures. The testing instrument is provided protection from corrosion and rust with Zinc and chrome plating and has been given a smooth and attractive finish in grey and blue color.
