During the production process of PET Preform which is blow moulding technique, it can easily get stressed due to strain distribution on their base or on the walls. Such type of defects can lead to damaging issues in the final bottle production like cracking, bending, deforming of shape etc. It can have a deformed design or produce misbalancing. To predict the defective issues, the preform is assessed utilizing Polariscope strain viewer. The device is having two standard designed light sources under which the defects are clearly visible. The lamps include monochromatic light and sodium lamp. It is dependent upon the principle of refractive index. In case the preform has stress defect the refractive index passing it will modify the path and will produce a coloured pattern. The defective patterns on PET preform can be compared with the standard defect chart containing all the patterns. Get Polariscope Ahmedabad with all the latest features and facilities for testing.
Heat Deformation - HDT/VSP Tester is a consistent tool useful for determining the ability of a given polymer to bear load at elevated temperatures. Accurate and reliable deflection or deformation is an important component in the plastics industry.

TP310 is a prominent color measurement instruments used in many mainstream industries which have been designed and manufactured by competent engineers and scientists of Presto Stantest. The instrument has many advantages of other international standard color measurement instruments.
Presto Melt Flow Index Tester is used for evaluating the flow properties of molten plastics or resins. The Melt flow Index of thermoplastic materials is defined as the rate of flow (in grams per ten minutes) of extrudates of molten resins through a jet of a particular length and diameter.
The Presto Melt Flow Index Tester - NXG Model is a reliable instrument used for evaluating and analyzing the flow properties of molten plastics or resins. The determination of the melt flow index of plastic materials is an important parameter in the evaluation of its quality.
