The first mold has a plurality of first protrusions. The first mold presses a metallic material to form recesses corresponding to respective shapes of the first protrusions in a surface of the metallic material. The second mold has a plurality of second protrusions. After the first mold presses the metallic material, the second mold presses the metallic material, thereby deforming each recess into an undercut shape. A height of each first protrusion is greater than a height of each second protrusion. A tip angle of each first protrusion is smaller than a tip angle of each second protrusion."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Surface roughening apparatus for metal stock and surface roughening method for metal stock","description":"A surface roughening apparatus includes a first mold and a second mold.
