H13 Tool Steel Vacuum Hardening & PVD Coating Blueprint<\/h2>\n

Executing high-performance H13 tool steel mold building requires strict thermal treatment protocols and 5-axis CNC machining:<\/p>\n

\n
\n

Vacuum Heat Treatment (50-54 HRC)<\/p>\n

H13 steel blocks undergo computer-controlled vacuum quenching followed by triple tempering. This establishes a uniform 50\u201354 HRC core hardness, maximizing impact toughness while eliminating micro-cracking during high-speed CNC milling.<\/p>\n<\/div>\n

\n

PVD Ceramic Coating for Gate Protection<\/p>\n

For highly abrasive 50% glass-filled compounds, we apply thin PVD TiN or CrN ceramic coatings to H13 gate inserts. This increases surface hardness above 65 HRC, protecting gate orifices from high-velocity fiber wash-out.<\/p>\n<\/div>\n<\/div>\n<\/section>\n
