NAK80 Mold Steel Tooling Engineering & EDM Blueprint<\/h2>\n

Executing precision NAK80 steel Kundenspezifischer Formenbau<\/strong><\/a> requires careful CNC cutting feeds, EDM copper electrode profiling, and hand polishing:<\/p>\n

\n
\n

Pre-Hardened 40 HRC Core<\/p>\n

Pre-hardened via precipitation age-hardening to 37\u201343 HRC. This eliminates post-machining quench distortion, allowing Jucheng to cut true-to-CAD cavity dimensions directly on 5-axis CNCs.<\/p>\n<\/div>\n

\n

Pinhole-Free EDM Sparking<\/p>\n

NAK80\u2019s uniform copper-aluminum-nickel alloy structure responds predictably to sinker EDM spark erosion. It produces clean, even VDI matte textures without microscopic pinholes or carbon buildup.<\/p>\n<\/div>\n

\n

Laser Weldability & Maintenance<\/p>\n

NAK80 features excellent weldability. In the event of engineering changes (ECOs) or parting line wear, our toolmakers deposit matching NAK80 wire using micro-laser welders without causing local heat distortion.<\/p>\n<\/div>\n<\/div>\n<\/section>\n
