How does Presto cupping strength tester work?

Most metals are quite strong and can withstand a lot of force before they break. However, there are some metals that are more brittle than others and can break more easily. In order to test the strength of these metals, it is important for the manufacturers to ensure that these metals will be able to withstand external forces. Thus, to test the cupping strength of metals, it is important for the manufacturers to test the right quality of materials to ensure the quality of products will be delivered. Thus, we at Presto have designed high-quality lab testing equipment known as a cupping strength tester that is used to test the cupping strength of the machine and ensure that quality material will be delivered. This amazing lab testing instrument will help to ensure the cupping strength of metal components, painted metal sheets, and non-ferrous metals. Here in this blog, we will discuss brief information about the Presto cupping testing machine and how this quality lab testing equipment is used to test the cupping strength of materials. But before, let us discuss a brief about cupping strength and why it is considered to be an important property of metals to be tested.

What is the cupping strength of metals?

The cupping strength of the material is defined as the strength of the material to resist the external load. The cupping strength of metals will be determined by their hardness. The harder the metal will get, the higher will be its cupping strength.

This is because hard metals are more resistant to indentation and crushing than softer metals. For this reason, testing the cupping strength of a metal is important in order to determine its overall durability and performance. Thus, we at Presto have designed high quality cupping strength tester that helps to test the ductility of metals with Presto cupping strength tester.

Now, let us discuss more information about this lab testing equipment.

Working of Presto cupping testing machine

If you want to conduct a cupping strength of metals, then you can easily follow the steps mentioned below.

  • To operate the machine, you can easily insert the zero plate in the sample holder slot and adjust the ball surface.
  • After that, you can adjust the dial gauge to zero at this position.
  • Remove the zero plate and fit your job sample in the slot provided.
  • Tighten the sample through the Front wheel handle. Now test the sample by rotating 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.
