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.
Trusting by the best, serving the best
The Tensile testing Machine is highly recommended for evaluating the tensile strength of products and materials. The equipment is based on the Constant Rate of Traverse (CRT) principle. It is equipped with an upper jaw and a lower jaw. Universal Tensile Testing Machine is a reliable piece of equipment which is widely used for checking tensile strength of a product/sample. One of the most common mechanical testing techniques used to determine tensile strength, this is a method wherein controlled tension is applied to a sample until it fully fails.
Thus, the material properties of the sample can be easily determined by this test. It involves measuring the force required to elongate a sample under test to breaking point. Using this test, manufacturers and quality managers are able to determine the core strength of their products.
