• Custom Forging Processes:
  • Closed-die forging (up to 5,000-ton press capacity)
  • Precision machining (±0.1mm tolerance)
  • Heat treatment (quenching/tempering per ISO 4885)
• Surface Enhancements:
  • Hot-dip galvanizing (ISO 1461)
  • Shot blasting (SA 2.5 standard)
  • Anti-corrosion coatings (Rilsan, Dacromet)
