PET bottle are manufactured via blow moulding technique. This process involves melting of PET material and then pouring of the material into Preform structures. These shapes are first cooled down and the taken for multiple testing procedures. As it is believed that if the PET preform is OK as per the quality standards, the bottle manufactured further will also be as per the criteria set. The preform while heating, melting cooling process sometimes gets stress or strain distribution on its surface which is not corrected can deliver damaging quality outputs in the final bottles. As these defects cannot be seen through naked eyes, Polariscope strain inspecting machine is used. The machine has two special lights equipped – Monochromatic light and sodium light. Under these lighting conditions the defects are visualized clearly. The base platform used for testing has angular standard template at 90 and 45 degree angle.

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.
