How to install tearing strength tester machine with simple steps?

 The main cause of any material like paper and thermoplastic films getting torn is through snag and pull. The initial hole is small, but if these materials will be pulled further, the hole can become much larger. Thus, testing the tearing strength of paper is important to make sure that the right quality of material has been delivered to the customers. Thus, we at Presto have come up with one of the amazing lab testing instruments known as the tearing strength tester. This is a widely used testing instrument that is helpful in determining the tearing strength of paper and plastic films under controlled test conditions. Here in this blog, we are going to provide you the information about the installation of a tearing strength tester and how this lab testing instrument is useful in determining the tearing strength of paper and plastic films. So, let us get started!



Introduction about tearing strength tester

Tearing strength is an important factor to consider when testing the quality of materials. The Presto Elmendorf tearing strength tester is a reliable and easy-to-use lab testing equipment for testing the tearing strength of various materials. The tearing strength testing machine is highly useful in measuring the internal tearing resistance of materials. This force is perpendicular to the plane of the paper when propagating a single rip or tears by measuring the force required to continue the slit previously cut in the material. The Presto tearing strength tester can be used to test a variety of materials, including paper, textiles, and plastics. With this tester, you can quickly and easily determine the tearing strength of your material, and ensure that it is up to par.

Below we have listed the features of the Presto tearing strength testing machine.

  • The unit of measurement is “mN” i.e. mega newton.
  • The laboratory equipment comprises a falling pendulum to cover various angles.
  • The instrument is supplied with cutting templates, a board, and a cutting knife for preparing a sample for the test.
  • There is a start and stop functions to hold the pendulum for safety.
  • The test parameters include peak load, median load, and tearing strength.
  • The procedure is done to determine tearing strength that involves a cut in the center. An opposing tail, known as the “tongue” is duly clamped in the instrument.
  • High-Quality rugged structure with the corrosion-resistant main body
  • Falling pendulum-type instrument
  • Single-handed hassle-free operation
  • Highly accurate test results under multiple pendulum weights
  • Strong gripping fixture for holding test samples
  • Pendulum release mechanism to cover the various measuring range
  • Inbuilt calibration weights

Test The Ductility Of The Material With Presto Cupping Strength Tester

Image
  In order to ensure the safety of structures and products, it is important to test the ductility of metals. Ductility is the ability of a material to deform under tensile stress, and it is considered to be an important property of metals. There are several methods of testing ductility but the cupping strength test is one of the common tests that will be performed on the metals to determine their ductility. This method involves measuring the amount of deformation that occurs in a metal when it is subjected to a constant tensile force. The results of this test can be used to determine the toughness of a metal. Testing the ductility of metals is important because it can help to ensure the safety of products and structures. Presto offers a high-quality cupping strength tester that will help to measure the draw ability of material, especially the metal sheets.  Here in this blog, we are going to discuss brief information about the Presto cupping strength tester and how this lab testing e

Cut The Specimen In A Circular Shape With Presto GSM Round Cutter

Image
The paper industry is highly competitive, and manufacturers are always looking for ways to improve the quality of their products. One important aspect of quality control is to check the grammage of the paper. In order to ensure that their paper products meet the desired standards, manufacturers will often cut the paper into small specimen pieces and then weigh them. Thus, to ease your cutting of paper we at Presto have come up with one of the highly efficient  lab testing instruments  known as the   GSM round cutter . The Presto GSM round cutter is a versatile and precise circular cutting tool that can be used for a variety of purposes. It features a durable, stainless steel blade that is ideal for cutting through tough materials, and the ergonomic design makes it comfortable to use. The cutter also comes with a safety guard that helps to prevent accidental cuts, and the blade can be replaced when it becomes dull. Here we are going to discuss brief information about how you can cut the

Test surface coatings against corrosion with Presto salt spray chamber

Image
In today's marketplace, customers expect manufacturers to deliver products that meet their high standards. Unfortunately, meeting these standards can be a challenge, especially when it comes to ensuring that products are free of defects. As a result, many manufacturers go to great lengths to test their products before they are shipped to customers. By doing so, they can avoid the hassle and expense of dealing with returns and refunds. Thus, if you are a metal products manufacturer, then testing the surface coatings of your products is of an utmost important task. Therefore, you can easily test the corrosion resistance of surface coatings with the Presto  salt spray chamber .  This is one of the versatile  lab testing equipment   that will help you to assess the rust-proof ability of components with ease. It will provide you with complete testing of surface coatings against real-life weathering conditions. This  corrosion resistance test chamber  will help you to evaluate the corr
