Gelbo Flex Tester

Approx Price: Rs 95,000 / Unit 

Gelbo Flex Tester is used for determination of flex resistance of flexible barrier materials. Pinhole formation is the criterion presented for measuring failure, but other tests such as gas transmission rate or water vapour permeability can be used in place of the pinhole test. The flexing action consists of a twisting motion, followed, in most cases, by horizontal motion, thus, repeatedly twisting and crushing the film at a specified frequency.

 

The Globe Gelbo Flex Tester for determination of flex durability of flexible barrier materials consists of a pair of cylindrical mandrels for holding the test specimen, an eccentric and link mechanism to give a movement of either 155 mm or 80 mm to one of the mandrels, arrangement to rotate the moving mandrel during the initial part of the travel, a motor operated arrangement to give motion to the eccentric at a specified frequency, and a digital type pre set counter with infra red sensor and memory back up to retain the count of total number of operating cycles in case of power failure and to automatic stop the motor after the desired number of operating cycles.

 

The test specimen is held on the mandrels with the help of double sided adhesive tape. The axes of both the mandrels are horizontal and coincide with each other. One of the mandrels is held firmly during the test. Linear movement is given to the moving mandrel with the help of an eccentric pin and link.

    Tensile Testing Machine

    Approx Price: Rs 75,000 / Unit 

    Tensile strength and elongation are the two prime characteristics of most of the raw materials, whether they are metals; or non metals such as rubber, leather, textiles, plastic, paper; or finished products such as rods, wires, ropes, yarns, belts etceteras. These two properties often play a major role in determining the suitability of any raw material for any specified application. It is, therefore, of utmost importance to determine these characteristics accurately, conveniently, and quickly.

     

    The GlobeTensileTestingMachines provide a relatively inexpensive way for determining the tensile strength and elongation of a variety of raw materials such as rubber, leather, fabric, plastics, belts, wires, etceteras. They are based on constant rate of traverse principle, in which one end of the test specimen is held in a stationery grip while the other end is moved at a known fixed speed with the help of a motor, gear box, and screw arrangement.

     

    In electronic type tensile testers, the load exerted on the stationary grip is measured by a load cell and is displayed on a digital indicator. The indicator has a peak force retention memory, which can be recalled to display the maximum load exerted on the test specimen before its failure. An overload protection relay is provided to automatically stop the motor if the load exerted goes above the maximum capacity of the load cell.

    Vicat Softening Point Apparatus High Temperature

    Approx Price: Rs 75,000 / Unit 

    Vicat softening temperature of plastics is the temperature at which a standard flat-ended indentor penetrates 1 mm into the surface of the material under test under a specified load. The test is conducted by placing a test specimen taken from the sample under test on a flat platform inside a liquid bath and applying compression load over its upper face through a flat-ended indentor. The load is applied by placing dead weights on the upper end of the indentor. After the test specimen attains the temperature of the bath, the bath temperature is increased gradually till the indentor penetrates by exactly 1 mm into the test specimen. The bath temperature in degrees centigrade at which this happens is reported as the Vicat Softening Temperature of the sample under test.

     

    The Globe Vicat Softening Temperature Apparatus for plastics consists of a hinged metallic frame which serves as support for the test specimen. The frame is fitted with a bush for guiding a rod with a hardened indenting tip at its lower end and a loading platform near its top to place the weights on. A dial gauge is fitted at the upper end of the frame to measure the movement of the rod. The parts that are immersed in the bath during the test are made from brass. The indentor is made from high speed steel.
