Bursting Strength Tester Genie 2.0

Are you looking for the perfect testing instrument to determine the bursting strength of materials? If yes, then we suggest you go with Presto bursting strength tester-digital. It is the perfect device for anyone who wants to find the bursting strength of Paper/Paperboard. It’s packed with features that make everyday life easier and more productive. It’s the perfect device for manufacturers in the packaging industry, to easily determine the bursting strength of corrugated boxes, cardboard boxes, and other related products. It consists of an electric motor with a speed regulator and gearbox fitted on a heavy cast iron base stand having leveling screws at its four corners.

The test specimens are mounted in jaws which are adjustable vertically by means of screw spindle provided with micrometer head for setting up desired value on scale plate attached. The digital model of this testing instrument has been equipped with various advanced features that make it easy to use. Bursting strength tester is the most widely used machine in industries where raw materials like paper, cardboard, cloth, rexine, leather, foil, etc. are used. It works on the very simple principle of applying pressure on the specimen until it ruptures. This pressure is not applied directly to the sample. Instead, it will be applied through a rubber diaphragm. When you easily calculate the bursting strength of materials, then you will be able to improve the quality of your material, by determining its bursting properties. This testing machine has been made up of high-quality parts and has very low maintenance. It comes with some low-cost consumables like diaphragm and glycerin which can be replaced without any hassle in case of wear and tear. The life of the diaphragm depends on the number of tests performed. To perform the test, the sample is clamped in the annular clamp. It is always advised to clamp the sample with nominal pressure. If the clamped sample is loose, it will tend to slip after the application of pressure. If it is too tight, more than required pressure needs to be applied. Thus, you should use nominal pressure to easily apply the pressure. The machine is very simple to operate and it comes with a calibration certificate as well. With its bright digital display, you will be able to view the testing results accurately.

The main purpose of the Presto bursting strength tester is that it provides you with accurate information about the bursting strength of materials. If you test this property of material, then there will fewer chances of box failure during the storage of products. The equipment is provided with a cam mechanism that is motor-driven which is used for increasing the fluid displacement on the lower side of the rubber diaphragm at a specified rate. There is a mechanism provided with the equipment that automatically lowers the pressure down and stops the motor automatically when the test cycle is completed. It has a rugged design to provide trouble-free performance for a long time.

The main unit of bursting strength tester-digital consists of various essential components like an operating wheel, lead screw, upper clamp, specimen placement area, lower clamp, load indicator, push-button for burst, and main switch. The load indicator control panel will show you the burst value of products, and provide you with buttons like Tare, reset, limit, etc. It comes with a maximum range of bursting (i.e. 40 kg/cm2). To operate this testing instrument, we have mentioned several steps below:

• When you start with the machine operating process, then you need to plug the machine into 3 pin-5 amp, power supply socket.
• Once the machine gets started, then the load indicator will show some values due to previous test values. But you can reset these values by pressing the TARE button and then the RESET button. When you press these buttons, then the load value will show zero reading.
• After that, you can prepare the specimen like a cardboard box, corrugated fiber sheet, or any other similar material. The dimensions of the cardboard specimen should be 100 x 100mm. A test specimen below these dimensions will not give accurate results. While preparing the specimen, make sure that there are no folds in the specimen.
• To place the sample accurately, you need to move the upper clamp of the specimen upwards by rotating the operating wheel in the anti-clockwise direction. Place the test specimen so that it completely covers the Lower clamp.
• Now rotate the operating wheel in a clockwise direction to bring the upper clamp down to hold the test specimen. Tighten the operating wheel to make sure that the test specimen is firmly held and there will be no slippage.
• Once you perform all the steps above, then you can commence the test. ‘

In this way, you can easily perform the bursting strength test of the specimen.
