How to select die-casting mold core steel for durability? A veteran engineer reveals the secrets for aluminum (ADC12/zinc alloy) molds. Compare materials like H13, 8407, DAC, and SKD61, understand lifespan differences across production volumes (small-batch/mass-production/thin-wall), and learn from real cases to avoid “expensive but short-lived” steel choices.
Injection Mold Core Steel Selection: A Veteran Engineer’s Guide to Lifespan & Best Practices
In the mold-making business for over a decade, I’ve seen too many clients fall into the same traps—wrong steel selection leading to rapid wear during mass production, or molds cracking after just a few thousand cycles. Today, let’s cut through the…
