Metal and its components are used in various industries in the production of different products. Thus, testing the different properties of these metal parts is an important part of the quality control process. The ductility of metals is an important part of quality control that helps to evaluate whether the material will be able to withstand plastic deformation without any rupture. The bend test that determines the ductility of materials will help manufacturers to ensure whether the material will be able to resist cracking and deformation or not. Thus, we at Testronix have designed a high-quality cupping tester machine that is used to test for testing the cupping properties of these metal sheets.

We at Testronix is a leading manufacturer of cupping strength tester and provide this high-quality lab testing instrument at the best and most affordable prices. This lab testing instrument will highly be used in the automobile industry to test the durability of metal sheets against deformation. Here in this blog, we are going to discuss brief information about the Testronix cupping strength tester and how this lab testing instrument is helpful in testing the ductility of metals. So, let us get started!

What is the Cupping Test?

The metal ductility test is an important part of the manufacturing process. By performing a metal ductility test, you can ensure that your metal products will not break during use. This is especially important for products that are being molded and users can easily determine the sustainability of materials and its resistance to deformations or fractures. You can easily conduct cupping strength tests on the materials and ensure that accurate products will be delivered to the customers with ease.

Testronix provides you with a high-quality cupping strength testing instrument that is used to test the ductility of metals against deformations. With its high-quality rugged structure and corrosion-resistant main body, one can easily conduct cupping strength tests on the materials. Let us discuss brief information about this high-quality lab testing instrument.

Introduction about Testronix cupping strength tester

The cupping strength tester is one of the highly advanced lab testing equipment that is used to test the cupping properties of the materials such as ductility and tensile strength. This will help the manufacturers to determine whether that material will be used in testing the durability of materials against dents and cracking. This lab testing equipment has been made with in-house cutting-edge technology and provides their customers will accurate testing results.

The mechanism of this high-quality lab testing equipment will be based on the hand-operated wheel that let the users test the sample by rotating its side gear handle. This lab testing instrument is based on brass clamping that makes it easy for the users to place the specimen firmly on the surface. The Testronix cupping strength tester is considered to be the best metal machine to test the draw ability of the materials and ensure that accurate products will be delivered to the customers.

Now, let us discuss how you can easily perform cupping strength tests on the materials with the help of Testronix cupping testing machine.

How do you perform the Cupping Test?

A metal ductility test can help you determine whether a particular material can be bent or pulled without breaking. This information is important when designing structures because it can help manufacturers to avoid potential accidents. Additionally, a ductility test can also help you determine the optimal shape and size for a given metal part.

To conduct the metal ductility test on the materials, users can easily follow the steps mentioned below:

  • When you are going to conduct the cupping strength test on the materials, then you need to prepare the sample first. For this, take the metal sheet and measure its thickness which should not be more than 2mm.
  • Once the sample will be prepared then you can easily operate this high-quality lab testing instrument by inserting the zero plate in the sample holder slot and adjusting it with the ball surface.
  • Adjust the dial gauge to zero and remove the zero plate and fit it in your job sample in the slot provided in this testing machine.
  • Tighten the sample through the font wheel handle and rotate its side gear handle.
  • View the condition of the sheet manually from the front side. Tighten the punching ball to the end position of the spindle bush.
  • Always keep a view of the dial gauge to check the correct stiffness of the sheet. On failure of the sample, note the reading on the dial indicator/gauge.
  • Release the pressure by moving the bigger gear wheel in the anticlockwise direction and then release the smaller gear wheel. Remove the sample from the sample holder slot.
  • Analyze the test specimen for any kind of cracks present in it.


In this way, manufacturers of the metal industry can easily conduct the cupping test on the specimen and ensure that accurate products will be delivered to the customers.
