This is the reason that the coatings and paints need to have a good quality to ensure protection of the surface for a long time after they are applied. The paints and coating products need to be tested thoroughly for their efficiency and strength for better quality control.

There are several properties of coatings that contribute to its good quality and efficiency such as porosity, adhesion, and agility of the coating against impacts and dents. The cupping is the most apt testing instrument that can be used for testing these properties of the coating materials and hence ensures the best quality and protection. Not only the paints and coatings can be tested using the Pacorr’s cupping machine. It can also be used for testing metals and sheets for their cupping properties that are depicted by testing the ductility, tensile strength and drawability of the metal sheets. This is done mostly in the automobile industry as the metal used in automobiles is prone to dents and cracking due to external impacts in an accident.

Pacorr’s Cupping Machine is the lab testing instrument that is used in different industries for testing the strength and cupping capabilities of metal sheets. The metal sheets used in industries such as automobiles are prone to cracks and dents when they have are subjected to an external force or impact such as an accident. The metal sheets must be able to withstand the cracking and must have enough ductility and drawability when they are subjected to such forces so that better safety and longer life of the products could be ensured. IN addition to metals, the paints and coatings are also tested using the cupping machines to check their adhesion strength, their elasticity and other physical properties. The manufacturers need to ensure that the paint and coatings are able to bear the forces that act upon the metals surfaces and stay on their place without cracking for better protection from corrosion of the surfaces on which they are applied.

The Pacorr’s cupping machines manufacturers and suppliers provide the machine with a punch that exerts force on the test specimen. The force is applied until the metal sheet cracks or the coating applied on the product shows any cracks. Once the cracks appear, the force application is withdrawn and the applied force is recorded. This gives the analysis of the adhesion of the coating along with its elasticity and also gives the information about the ductility of the metal and ability of the metal sheets prevent cracks on the surfaces upon exertion of external force.
