Investigation of Coatings Friction Coefficient Used in Production of Deep Drawn Packaging Cans

In technology of deep drawing of cans the use of lubrification oil has been replaced by coating finishes accordingly to packaged products. Wear of added coating can occur at edges and small radii where the average added coatings due to processing thinning reduces its size. Friction influences deep drawing parameters. If the optimal ratio can be established between coating selection, friction and deformation forces a better control and insight in deep drawing technology is possible. Investigation of friction coefficient for Gold lacquer, Overprint varnish and Alu pigmented lacquer for material TH 550 E2.8/2.8 FS 0.155 mm has been calculated with tribometer TOP 3.
