A strip of 220 mm wide by 20 mm thick is formed. 3-Cold Lamination/Rolling which aloud a maximum tolerance 0,05 mm 4-Stamping/Punching This stage counts with four stamping presses, In this process we get about 50% of slugs for each Ton of punched strip. 5-Annealing Treatment With this we obtain a Brinell hardness of 16 a 21 HB. 6-Surface Finish Surface treatment is sand blasted, vibrated and tumbled 7-Final Inspection QC department(gauge,mechenical test, surface quality) 8-Selection and Packing Boxes are marked with customers information QC -Testing The quality policy of Nansen Industries is to establish implement and maintain an effective assurance system.
