Ensure The Ductility And Strength Of Metals With Cupping Machines

In today’s era of modernization, metals are used in different production verticals to manufacture various domestic and industrial products. The numerous fields where metals are used include automobiles, industrial machines, electrical devices, and so forth. These fields in which metals are used are very critical where there is no room for defects and require high-quality of products that can ensure efficiency, high performance with the best level of safety. In these fields, there is no space for flaws as the errors in such fields can lead to various accidents which will create horrible consequences for the users and affect the life of the users. This let the manufacturers of metal products to be extra conscious regarding the quality of the products.

The manufacturers need to ensure that the highest quality of the products they produce with the use of best quality of testing procedures and testing devices. With the help of testing instruments, the producers can determine various properties of the metals like chemical composition, the physical strength that predict the behavior as per some given conditions. This helps the manufacturers in deciding different factors that are related to the safety of the product as well as the safety of the users and offer the best quality to the clients. To assure the quality of the metal products, it is necessary to commence some quality tests at the different level of production like raw material procurement, production process and end product. Ignoring the quality of the product will directly degrade the quality of the products.

One of the most popular tests which are performed on the metal goods is the cupping test. The test is conducted on the metals substrates that are duly painted or coated. The test is performed to test the ductility of the metals and to test the quality of the coated. The test sample is placed on the machine to create shearing forces on the very small area of the specimens that create a small cup on the side of the test specimen. The load sensor present on the indenture records the amount of shearing force applied to the metal plate. In this manner, the maximum value of force is calculated which is applied to the metals without cracking the material.

The test is also used to verify the ductility and the elasticity of the paints that are used on the metal surfaces. The cup shape formed in the metal products at the time of the test is analyzed to determine the cracks that are developed on the surface of the paints. Hence, it is used to verify the quality of the paints and metals both.
