How to operate the tensile strength tester efficiently?

Gaurav Malhotra

Plastics are a material that is used in many different industries, like food, beverages, and many more to manufacture different products. Testing the quality of the plastic will determine how long the product will last. Out of various quality tests, tensile tests are considered to be one of the essential quality tests that will help to determine the quality of plastics when exposed to high tensile forces. This test can be done with the help of a quality lab testing instrument known as a tensile strength tester. Presto being the leading lab testing instruments manufacturer offers high-quality tensile strength testing equipment digital model that is based on the principle of a constant rate of the traverse. This testing instrument has been equipped with an upper and lower jaw that helps to place the specimen accurately on the machine.

Here, we are going to discuss the working of a tensile strength testing machine. We will also discuss brief information about tensile testing and what it is used for. So, let us get started!

What is tensile strength testing?

Tensile testing is a type of mechanical testing that is used to determine the strength and elasticity of a material. This testing is often used on metals and plastics, as it can provide valuable information about a material's mechanical properties. By testing the tensile properties of plastics one can ensure the quality of materials. By conducting tensile strength tests on the materials, one can easily determine the material's yield strength, ultimate strength, Young's modulus, and other important properties.

Tensile testing is an important tool for understanding how materials will perform in real-world applications. It can be used to optimize material selection for specific applications and to predict how a material will behave under various types of loading. If you are working with plastics, then tensile testing is an essential part of ensuring that your materials will meet your performance requirements.

Presto tensile strength tester is one of the high-quality lab testing instruments that is used to test the tensile properties of the materials with ease. By conducting a tensile strength test with the help of the Presto tensile strength tester one can improve the performance of materials with ease. You can read more about the purpose of tensile strength tester in the plastic industry.

Introduction about Presto tensile strength tester

As we have discussed above tensile strength is considered to be the maximum stress a material can withstand without breaking. In the plastic product manufacturing industry, one can easily test the tensile properties of the materials and ensure that the material can sustain maximum stress when pulled. Presto offers a digital tensile strength tester that is based on the principle of a constant rate of the traverse. This high-quality lab testing equipment has been equipped with an upper and lower jaw to firmly place the specimen. The motor will be equipped with a gearbox and lead screw arrangement and has been incorporated with the special sensor connected with the load cell. This will help the users to assess the load exerted on the stationary jaw and directly indicate the readings in kgs.

This highly advanced lab testing instrument has been equipped with gripper jaws as well to hold fragile items. The bright LED display embedded in this lab testing instrument will help the users to view the test results with ease. If you are using Presto tensile testing machine then you can read about the top 3 secrets of successfully conducting the tensile strength test. Below we have listed the features and technical specifications of the Presto tensile strength tester.

Whenever you are going to conduct the tensile strength test on the materials then it is important to avoid these mistakes. You can also read a brief use of tensile strength tester in the plastic industry. Now, let us focus on the working of the Presto tensile tester digital model.

Working on Presto tensile tester digital model

To perform a tensile strength test on the materials, users can follow the following steps:

Start the machine by plugging it into a 5 amp switch.
After starting the machine, you need to place the specimen accurately and set the peak load indicator.
When you turn the rotatory switch in the down direction, the lower grip will be moved in the lower direction and it will increase the value shown in the indicator.
You can even turn on the rotatory switch when the specimen will get ruptured.
Once the above steps will be followed then stop the machine and display the load value and return to zero.
The elongation display will get frozen and you will get the memory switch on the load indicator to show the peak value.
You can even assess the peak value of the specimen to accurately conduct the test results.

In this way, a tensile test will be performed on the specimen. You can read what will happen when the material is subjected to a tensile test.
