Diamond-like Carbon (DLC)
Our DLC (Diamond-like Carbon) Kardia is made with great precision and with
superb properties of low friction, low noise, high wear resistance, and long
lasting life, even without lubrication. With an ISO9001¡G2000 certified quality system, we have developed a series of processing to
produce our Kardia hooks under highly specialized machines and fixtures imported
from Japan and other countries.

Definition of DLC:
Diamond-like Carbon (DLC) is graphite (SP2) and diamond (SP3) composed of a
mixture of graphite with good self-lubrication, diamond has a very high
hardness, so it is the One kinds of improvements can be self-lubricating
properties of the workpiece surface, the superior Coating Search.
DLC
Vacuum coating
principle:
It is through solid - gas - solid process of change.
Characteristics of DLC:
Hardness being HV1500 or more, superb wear resistance, low friction coefficient, coating thickness being about 1 micron, conducting heat very rapidly, strong bonding on substrate material, superb corrosion resistance, Superb anti-sticking and anti-biting between metal to metal.
Application of DLC:
DLC is widely used for tooling/molding, cutting tools, automotive parts and other areas; it becomes more and more popular in sewing machine applications. DLC coated hooks with Oil-free and hi-speed running are well recognized by the majority of this industry. It leads the trend of new hooks development.
Properties of Diamond-Like
Coating (DLC):
Amorphous and hydrogenated amorphous carbon films have high
hardness, low friction, electrical insulation, chemical inertness, optical
transparency, biological compatibility, ability to absorb photons
selectively, smoothness, and resistance to wear. It is one of the best
coating method for high speed machine. DLC coating has higher resistance to
wear comparing with Chromium or Teflon coating. It allows Kardia rotary hook running
without lubrication and have high durability. |
