Diamond Like Carbon coatings are the top choice for performance-critical applications where ultra-low friction and superior wear protection are essential.

  • Perfect for Surgical Tools and More: These coatings provide exceptional durability and reduced friction, making them ideal for the precise movements and harsh environments encountered by surgical tools, engine components, and firearms.
  • Performs Under Dry or Lubricated Conditions: Unlike many other coatings, DLC maintains its remarkable properties whether operating in the absence of lubrication or when immersed in various lubricants, offering consistent performance across diverse operational scenarios.
  • Excellent for Soft Metals and Polymers: DLC's unique characteristics allow it to significantly enhance the surface hardness and wear resistance of softer materials like certain metals and various polymers without compromising their base properties.

Machining and Cutting Tools

  • Drills, end mills, inserts, and taps benefit from AlTIN coating for high-speed machining.
  • Extends tool life.

Aerospace

  • Used in tooling for high-performance alloys and composite materials.
  • Ideal for titanium and nickel-based alloys.

Automotive

  • Applied on components and tools that undergo high stress and temperature, such as engine parts and gear cutting tools.

Medical

  • Used on surgical instruments and orthopedic implants for durability and biocompatibility.

Die and Mold Making

  • Coating improves the performance of tools cutting abrasive materials like glass-filled plastics or hardened steels.
