Abstract： Copper nanoparticles （Cu NPs） demonstrate remarkable advantages in mold lubrication due to their unique physicochemical properties. This review systematically summarizes the mechanisms，performance optimization， and practical applications of Cu NPs in injection/ stamping molds. Studies reveal that Cu NPs enhance high-temperature stability （withstanding 800∘C ）and environmental performance （ 62% reduction in carbon footprint） through dynamic lubricating film formation （friction coefficient as low as 0.07-0.12） ， surface modification synergy （extreme pressure load capacity up to 3.5GPa ），and self-healing mechanisms （23%-27% reduction in wear scar diameter）12.Experimental data indicate that lubricants containing O. 6% Cu NPs extend mold lifespan by 80%-150% and reduce maintenance costs by 30%29 . However，challenges such as high production costs （3 -5 times conventional lubricants） and insuficient long-term stability （>15% performance decay per 1000 hours） hinder large-scale applications.Future research should focus on green synthesis （e.g.，plasma-assisted reduction），composite materials（e.g. ， Cu@Ti3C2 ），and intelligent lubrication systems （（response time <50ms ） to overcome these barriers359. This work provides theoretical and technical insights for industrializing Cu NPs in mold lubrication.
