How Tensile Testing Specimen Prepared and Mounted for a Tensile Test?

Tensile strength testing is a fundamental procedure in quality assurance to evaluate the maximum load a material can withstand without breaking or deforming. Manufacturers across various industries conduct quality assurance tests to verify the strength of materials when subjected to tensile forces. By quantifying a material's stress tolerance, manufacturers can make informed decisions and guarantee the delivery of high-quality materials to their customers. Therefore, with the assistance of the Presto tensile strength tester, manufacturers can conveniently perform tensile strength tests on their materials, thereby ensuring the accurate delivery of products to their customers.

Presto is one of Asia’s top manufacturers of tensile testing machines and designs this quality testing equipment with highly advanced features. The digital model of the Presto tensile strength tester will help the manufacturers ensure accuracy in product quality.

In this blog, we will discuss brief information about the Presto tensile strength tester and how you can easily mount the specimen in this testing equipment for accurate testing.

Introduction to Tensile test and its Importance in Different Industries

As previously mentioned, the tensile strength test stands as a widely used quality assurance method, aiding manufacturers in confirming the durability of materials under the influence of tensile forces. Tensile strength testing serves a pivotal role across various industries such as automotive, aerospace, construction, and more. By precisely gauging the tensile strength of materials, manufacturers can readily make informed judgments about a product's appropriateness for its intended applications. Achieving this accuracy in test results is facilitated through the utilisation of standardised laboratory testing equipment, ensuring manufacturers maintain precise quality assessments. Presto digital tensile strength testing machine has been designed as per industrial standards and works on a constant rate of traverse principle. It has been equipped with an upper and lower jaw that makes it easy for the manufacturers to conduct quality tests on the materials.

Now, let us discuss brief information about the Presto tensile strength tester.

All about Presto digital tensile strength tester

The Presto Tensile Testing Machine comes highly recommended for assessing the tensile strength of various products and materials. This equipment operates based on the Constant Rate of Traverse (CRT) principle and features both an upper and lower jaw.

The upper jaw remains stationary, while the lower jaw can be smoothly moved at a predetermined fixed speed with the assistance of a motor. Test specimens are securely held between these two jaws, and the lower jaw is progressively adjusted to determine the tensile strength of the sample. The motor is equipped with a gearbox and lead screw arrangement, ensuring precise control. Additionally, the machine incorporates a specialised sensor linked to a load cell, which accurately measures the load applied to the stationary jaw and displays the reading in kilograms in a digital format.

To enhance stability and durability, the Presto Tensile Testing Machine utilises case-hardened lead screws. It is also fitted with a reputable motor and adheres to CE standard electrical wiring. The machine's modular design makes it easy to maintain and operate, ensuring a trouble-free experience. This digital tensile strength testing machine makes it easy for the manufacturers to conduct tensile strength tests on the materials. You can easily perform tensile strength test on the materials with the help of this quality testing equipment.

Now, let us discuss briefly how you can easily prepare and place the testing specimen on this quality testing instrument.

How to prepare and place the testing specimen on the Presto digital tensile tester?

To accurately prepare and mount the testing specimen on a Presto digital tensile strength tester, manufacturers can easily follow the steps mentioned below:

• Preparation of Rectangular Shape Specimen

• Cut a Strip of 25 mm width or the desired width having the appropriate length.

• Now mark the specimen strip as follows for measuring gauge length.  

• Marking should be done in such a way that the distance between the grips of the machine is exactly required as gauge length after clamping of the specimen.

• This distance can vary from test standard to test standard.

• Clamp the specimen from both ends to ensure proper and equal clamping force on the specimen on both ends.

• Placement of Specimen

• Place the lower side of the specimen between the lower fixed grips and tighten the grip firmly. (for pneumatic clamping, go to the menu, press Clamping ON/OFF, and select ON for lower gripping)

• Now bring the upper movable grip upwards so that the specimen can easily reach the grips. & Place the lower end of the specimen between the lower grips and tighten the grip firmly.(go to the menu, press Clamping ON/OFF, and select ON for upper gripping)

• Ensure that the lower limit switch ring is placed at a position that keeps a minimum distance of 25 mm.

• Make sure that the specimen is placed in the centre of the grips.

In this way, you can easily prepare and place the testing specimen on the tensile testing machine.
