Materials and Characteristics of Medical Mask Machine Blades:
Medical mask machine blades are typically manufactured from high‑quality tungsten steel or carbide materials. These materials provide sufficient strength and toughness, enabling the blades to withstand significant pressure and impact vibrations without chipping or fracturing. They also exhibit high thermal resistance, maintaining hardness and wear resistance even under elevated temperatures. Furthermore, the blades possess excellent oxidation resistance, anti‑adhesion properties, and diffusion resistance, contributing to their durability, reduced replacement frequency, and enhanced production efficiency.

Technical Requirements:
The specialized cutting tools developed by the research team at Wuyi University for KN95 mask production equipment demand exceptionally sharp cutting edges to improve production efficiency. Moreover, the tools must ensure repeated positioning accuracy within 0.005–0.01 mm to guarantee cutting precision. Additionally, superior toughness is required—achieved through military‑grade heat‑treatment technology—resulting in a toughness level 3–5 times that of conventional tools, thereby preventing edge chipping during high‑speed continuous production.
