slotting knife replacement for carton machines

Ma'anshan Guangchuan Machinery Knife Mold Technology Co., Ltd. is a manufacturer specializing in the production of high-performance industrial blades and precision molds. These industrial serrated fan-shaped slotting blades for corrugated box machines feature precision-ground, sharp serrated edges and a standard fan-shaped slotting structure, combined with a design featuring precisely positioned mounting holes. They are specifically engineered for slotting machines, die-cutters, and print-and-slot machines used in high-speed corrugated box production lines. We utilize high-wear-resistant alloy tool steel and advanced vacuum heat treatment processes, combined with micron-level CNC precision grinding technology, to ensure precise and consistent slotting cuts on all types of single-, double-, and triple-wall corrugated board—free of burrs, crushing, or paper residue. This significantly enhances the blades’ impact resistance and service life, effectively reducing blade change frequency and production downtime, and substantially improving the efficiency of your carton production line and the quality of finished products.
