While Bottle manufacturing, first stage which appears is the preform production. These structures are made using blow moulding technique and while encountering instant heating and the cooling method they can easily generate stress or strain distribution on their surfaces. It is considered to be some kind of defects which can also affect further bottle production. Such type of defects can disturb the shape, balance and strength of the bottle. Unfortunately, the defects are not visible through naked eyes. Hence, we need equipment which is capable of visualizing the strain distributions on the wall area. Strain viewer by Presto Group brings you an innovative technology which helps the user to see the defects clearly and also compare them with the standardised defect chart and take required actions to improve the quality. The machine is fitted with Monochromatic light and Sodium lamp under which the preform defects are clearly seen. The test platform has a standard template for placing the preform. Get Polariscope in Pantnagar for testing preform quality rapidly and precisely.
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.
