High Strength Steel Blanking Solutions for Automotive Applications
Looking for a reliable high strength steel stamping solution for automotive components? Our factory specializes in manufacturing precision punches, dies, guide posts, ejector pins, and other tooling components engineered for AHSS (Advanced High-Strength Steel) and ultra-high strength steel (UHSS) blanking applications.
🔧 1. Industry Pain Points & Challenges
Stamping high-strength steels (HSS, AHSS) for automotive components comes with serious tooling challenges:
❗ Severe die wear & chipping due to material hardness (600–1,200 MPa tensile strength)
❗ Frequent burr formation, affecting dimensional accuracy
❗ Punch breakage or edge cracking during high-speed production
❗ Short tool life, leading to costly downtime and more replacements
❗ Unclear material-to-tool compatibility for new EV lightweight parts
✅ 2. Our Solution – Engineered for HSS Stamping
We offer a complete tooling component package optimized for high-strength steel blanking, including:
🔩 Precision Punches & Dies
HRC 62–68 hardness for wear resistance
High toughness to resist micro-chipping
Optional coatings: TiN, TiCN, AlCrN for reduced friction & heat
🧊 Optimized Ejector & Guide Systems
Precision-fitted sleeves reduce vibration & misalignment
Ejector systems with high fatigue resistance for long-run use
🌀 Custom Anti-burr Finishing
Deburring brushes and post-grind polishing reduce burr risk
Precision ground cutting edges to ±0.002mm
