Copper Circle
Overview
MEI supplies copper circles blanked from precision-rolled sheet, ready for spinning, deep drawing, and pressing — in diameters from 20 mm right up to 1500 mm and thicknesses up to 50 mm for heavy pressed components. Uniform thickness across the blank and properly controlled annealing mean fewer rejections on the press and a consistent finish on the final product.

WHY MEI
Located close to the Jagadhri–Yamunanagar utensil cluster, we understand drawing-quality requirements deeply — soft, uniform circles that spin and draw without cracking or earing, in one of the widest diameter ranges in the country.
