PET preforms during their production process often produce stress distribution throughout their wall, and at the bottom. This happens due to the uneven heating and cooling process during the blow moulding technique. Due to this, the strain defects appear in the bottle, which is not seen through naked eyes. Such type of defects may be not seen but can lead to huge issues, like the bottle structure can get weakened, or they can easily fall off due to imbalance etc. To avoid this situation, it is important that the defects are detected at an early stage of Preform and can be corrected throughout the production process. Polariscope strain viewer is designed to inspect such defects under two special type of source light. One is sodium light and other is monochromatic light. The test area has an engraved template designed to place the preform at two angles – 45 and 90 degrees. It offers a sharp and clear view of the defects. Purchase Polariscope in Haridwar to check the quality of PET preform and implement required improvements in the Bottle.
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.
