Deep Cavity 5-Axis Milling<\/strong><\/td>\nH13 is the standard for die-casting. We use simultaneous 5-axis milling to reach deep into complex mold cavities with shorter, more rigid tools.<\/td>\nOur high-speed Haas\/Mazak centers minimize tool deflection, ensuring perfect draft angles and wall thickness for complex aluminum and zinc casting dies.<\/td>\n<\/tr>\n
Gun Drilling for Cooling Channels<\/strong><\/td>\nMachining deep, precise internal water lines for thermal management within the mold block.<\/td>\nWe ensure precise alignment of cooling channels to maximize heat dissipation, preventing “hot spots” in your production molds.<\/td>\n<\/tr>\n
Hard Milling (Post-Quench)<\/strong><\/td>\nFinish-machining H13 after it has been hardened to 48-54 HRC using advanced ceramic and CBN tooling.<\/td>\nAllows us to correct heat-treat distortion, ensuring that sliding mold cores and parting lines fit with zero clearance.<\/td>\n<\/tr>\n
Surface Nitriding Prep<\/strong><\/td>\nMachining H13 surfaces to Ra 0.8\u03bcm to prepare for gas nitriding to achieve extreme surface wear resistance.<\/td>\nExtends the life of your dies when molding abrasive glass-filled plastics or during high-pressure metal casting.<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<\/div>\n

Fabrication Guidelines for Tool Steel H13<\/h3>\n

Hot-Hardness Property:<\/strong>
\nH13 is designed to maintain its hardness and strength even when exposed to high temperatures (up to 540\u00b0C). Tip:<\/strong> This “red hardness” makes it the premier choice for tools that contact molten metal.<\/p>\n

Thermal Fatigue Resistance:<\/strong>
\nH13 is highly resistant to “heat checking” (micro-cracks caused by repeated heating and cooling). Tip:<\/strong> We recommend a vacuum hardening process with a controlled nitrogen quench to maximize this property.<\/p>\n

Avoid Sharp Corners:<\/strong>
\nThermal stress concentrates at sharp edges. Tip:<\/strong> Always design internal radii (fillets) into mold cavities to prevent premature cracking during the die-casting cycle.<\/p>\n

Machinability:<\/strong>
\nIn the annealed state, H13 is moderately easy to machine (approx. 70% of 1212). However, it is abrasive to tools. Tip:<\/strong> We use TiAlN coated tools to handle the heat generated during roughing passes.<\/p>\n<\/div>\n

Primary Applications<\/h3>\n

Die Casting Dies<\/strong>
\nThe industry standard for aluminum, magnesium, and zinc high-pressure die casting mold cores and cavities.<\/p>\n

Hot Extrusion Dies<\/strong>
\nDies and mandrels used to push hot metal through profiles, requiring high strength at elevated temperatures.<\/p>\n

Plastic Injection Molds<\/strong>
\nUsed for high-production molds and those processing abrasive engineering plastics where 420 stainless is not required.<\/p>\n

Forging Dies<\/strong>
\nHammer and press dies for hot-forging steel and non-ferrous components.<\/p>\n<\/div>","protected":false},"excerpt":{"rendered":"
