We make available Polariscope Meter that is specifically and especially useful for Pet Preform Manufacturers. Our offered Polariscope Meter is an optical inspection device used to detect internal stresses in plastics. Polariscope Meter, offered by us, is composed chiefly of a light source and two crossed polarized sheets. The light source of Polariscope Meter is mounted beneath one sheet and is powered by external power source of 220V AC with earthen pin. Material to be examined is placed between the two sheets and viewed through the sheet mounted opposite the light source sheet. A defect in preform can be easily detected by using this equipment. When preform is held parallel to viewing field, color pattern is seen known, which is known as isochromatic fringe. This indicates magnitude of the stresses introduced during moulding process. Working Of Polariscope Meter When a Preform is held at 45o to viewing field, a colored pattern known as isoclinic is seen, and this indicates direction of stresses. The advantage of the Polariscope Meter is that crystallinity is readily identified, not only can the Molecular birefrigetent flow lines (fringes) be seen in color but the black isoclinic lines are visible when the preform axis is parallel to the molecular orientation strains. A special and removable stage is provided to rapidly obtain the correct alignments of the preforms when viewing for observations of the fringes. Preforms are aligned at 45o to the polarizing axis and at 0o to view the black isoclinic. The stage allows for the rotation of the Preform whilst viewing. With higher end model a preform of 20 liters jar can also be checked with the length of preform up to 24 inches (600 mm).

Polariscope is an optical device and used for the defect identification in PET preforms. Preforms develop internal defects due to external strain. These defects might create weak points when blown moulded into bottle. To avoid this, the preforms are tested prior mass production. The device has an incident light and polaroid lenses. The incident light passes completely through the test medium without any refraction. As a light encounter a defect, it changes its path doubly and create different patterns of light. Due to polaroid nature of lenses, the birefringence of light forms. This birefringence creates different patterns depending upon the type of the defect. The pattern can be matched with the defect chart to identify the defect. The sample is tested at two different angles, 45° and 90°. The strain viewer can be used for PET preforms and glasses also. It is equipped with two types of incident light Monochromatic and Sodium. The device can be connected with the computer for defect identification and report generation.   The Polariscope computerized model is supplied complete with: Viewing Area: 260 * 240 mm Display: Pictorial through Inbuilt Software Power: 220V, Single phase, 50 Hz Lights: CFL Light Sodium Light Standard Template Measuring Angle: 45º and 90º

:A preform is held parallel to viewing field to study a colour pattern known as isochromfringe.This indicates magnitude of the stresses introduced during moulding process.andWhen perform is held 45 deg to viewing field a coloured pattern known as isoclinic is sethis indicates direction of stresses.

  Presto's Glass & Plastic Polariscope - Strain Viewer is the best and highly effective testing device which is used to measure the residual stresses and strains that are introduced during the manufacturing process of the products that severely affects the strength of the product. MODEL      PSPL - G20 Presto's Glass & Plastic Polariscope - Strain Viewer is the best and highly effective testing device which is used to measure the residual stresses and strains that are introduced during the manufacturing process of the products that severely affects the strength of the product. These effects can be harmful as it may contribute to the product’s failure in service or it can be beneficial, as for example in the inducement of compressive stresses in the surface layers of toughened glass to increase its strength in service. One of the most powerful methods, where the product is made of transparent glass or plastics, is based upon the photoelastic technique which involves the passing of polarized light through the product and interpreting, qualitatively or quantitatively, the resulting optical interference pattern. In the case of glass products, it is usually the residual stresses which are measured whilst in the case of plastics molding, casting or extrusions it is the strains which generally are of importance. The testing instrument is manufactured by considering relevant parameters and various standards that are introduced by standardized and reputed authorities. The Presto Polariscope strain viewer for glass and plastics is made to easily detect the defects present in preforms and glass products. This is one of the most accurate quality lab testing instruments that make the use of a monochromatic light source for visual inspection of the testing specimen.  Users can easily rely on this lab testing equipment to test the deforms present in plastic and glass products. The sample will accurately be placed in the testing area and can be tested to evaluate different types of defects in the specimen. Users will get a sharper and clearer optical viewing experience with the use of this quality lab testing equipment. Presto offers the best Polariscope strain viewer price to our clients. With the help of this quality lab testing equipment, one can detect stress, strains, or even cracks present in plastic and glass products. The wide viewing area present in this testing equipment will give a sharper and clearer optical experience to the users. The samples can easily be tested at 45 and 90 degrees of angles.

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. The instrument is also provided with an instruction manuals and a conformance certificate that can be traced to any of the NABL approved laboratories.

In the field of present engineering development, stress strain analysis by photoelastic methods plays an important role. This method provides a means for visualisation of stress patterns spread across the cross section of loaded specimen and determination of principle stress difference in the whole field. The magnitude of stress at every point can be determined in the simple way by using usual Principle Stress Separation Technique.
