Precision Heavy Metal Stamping Services

We conquer the mechanical challenges of heavy gauge processing. By leveraging our 450T precision press lines with in-house progressive die tooling, we stamp high-strength alloys—including SPCC, SUS304/316L, and C17200 beryllium copper—without material fracturing or die failure.

Our core edge lies in integrated manufacturing: we seamlessly pair heavy metal stamping with in-house insert molding to produce fully integrated EV busbars and high-voltage connectors under one roof.

Backed by Zeiss CMM and in-die inspection systems, we deliver certified structural components for demanding electric vehicle applications.

  • CRITICAL PRODUCTION RISKS

    Are Heavy Metal Stamping Defects Disrupting Your Production?

    Stamping thick-gauge alloys on high-tonnage progressive presses pushes standard tooling to physical failure. Without rigid die alignment and engineered shear control, violent reverse tonnage, edge tearing, and springback will destabilize tight tolerances and compromise downstream assembly.

    • Violent Snap-Through Shock & Tool Chipping

      Blanking high-strength alloys creates extreme reverse tonnage at the precise moment of material breakthrough. In high-tonnage progressive stamping, this unmanaged shockwave causes press frame deflection, carbide punch micro-chipping, and premature fatigue across all progressive stations.

      Consequence: Unplanned tool maintenance, alignment drift, and catastrophic die breakdown during high-volume production.

    • Shear Edge Fracturing & Excessive Burr Escalation

      Piercing thick metals exceeds standard shear-to-break limits if die clearances are improperly calculated. Excessive tensile stress causes uncontrolled material tearing rather than a clean shear zone, resulting in heavy burr growth and non-perpendicular cut profiles.

      Consequence: Severe risk of insulation breakdown in power electronics, forced manual deburring, and poor mating alignment in critical assemblies.

    • Severe Springback & Progressive Pitch Drift

      Thick structural alloys retain high elastic recovery after forming operations. Lot-to-lot coil hardness fluctuations cause unpredictable springback variations between die stations, throwing off the feed pitch and ruining critical hole-to-edge tolerances.

      Consequence: Angular deviation, automated assembly line jams, and costly Cpk process capability failures.

    Don’t let manufacturing risks derail your project. You don’t just need a supplier who can run a machine; you need an engineering partner who masters the complex science of precision Progressive Die Heavy Stamping art.
