PET Preform while their manufacturing process which is blow moulding technique, can exhibit stresses and strain defects on their base or wall. Such defects can lead to issues in the final bottle production with disturbed appearance or imbalance issues. To inspect these defects the preform samples are tested under Polariscope strain viewer. The machine is equipped with two standard light sources under which these defects are clearly visualized. The light sources include monochromatic light, sodium lamp. It is based on the principle of if the preform contains stress defect the refractive index passing it will change its path and will generate a pattern. The defect patterns can be compared with the preform defect chart having all the patterns. The charts is standardized and can help in assessment of the issue. Get Polariscope in Bangalore with all the latest features.
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.
