DLC Coating
What’s DLC Coating?
DLC refers to a family of amorphous carbon coatings that mimic some of the key properties of diamond—mainly extreme hardness, low friction, and high wear resistance. These coatings are applied using Physical Vapor Deposition (PVD) or Chemical Vapor Deposition (CVD) methods and are known for their excellent surface smoothness and biocompatibility.
DLC coatings are widely used across industries including automotive, aerospace, medical, electronics, and mold tooling to extend tool life, reduce energy loss due to friction, and improve durability under harsh operating conditions. Their unique mechanical and chemical properties make them ideal for high-precision and high-performance components.

Visit our FAQ center for more questions.
What are the main advantages of DLC coatings?
DLC coatings offer lower friction, increased hardness, and excellent resistance to wear and corrosion, significantly extending the lifespan of tools and components.
Is DLC coating suitable for mold components?
Yes, DLC is particularly effective for mold components such as ejector pins, sliders, and cores due to its durability and smooth surface finish, which improves part release and reduces maintenance.
How thick is a DLC coating?
The coating thickness typically ranges from 1 to 3 microns, depending on the specific application and method of deposition.
