Industrial flat-bottom cutting knives are essential consumables in automated production lines, featuring a "flat-bottom" design optimized for rapid equipment installation and secure clamping. Typically crafted from special alloy steel or hard alloys with wear-resistant coatings, they maintain sharpness and dimensional stability during continuous operations such as die-cutting, slitting, and granulation. As the "sharp teeth" directly executing machine cutting, their selection and condition directly determine processing precision, production efficiency, and cost control in industries like packaging, rubber and plastics, and food.
