Multi-Layer Copper Sleeve Steel Core Embossing Roller for Fine Leather Grain Pattern HRC58 600-2000mm
Multi-Layer Copper Sleeve Steel Core Embossing Roller
Key Features
  • Multi-Layer Construction: Combines a hardened 42CrMoA steel core (HRC56-60) for structural integrity with a high-purity electrolytic copper sleeve (1.5-4mm) for superior engraving capability.
  • Copper Engraving Precision: The copper layer enables ultra-fine pattern engraving with sharper edge definition and deeper relief compared to direct steel engraving, ideal for premium leather grain reproduction.
  • Metallurgical Bonding: Advanced metallurgical bonding or precision shrink-fit ensures the copper sleeve remains securely attached under high-pressure embossing conditions without delamination.
  • Replaceable Sleeve Design: When the copper sleeve wears, it can be re-engraved or replaced, extending the overall roller life and reducing long-term tooling costs.
