DLC Coating Manufacturer - Hardware Vacuum Coating - Hardware DLC Processing - Hardened and Wear-Resistant Treatment for Hardware Accessories
DLC (Diamond-like Carbon), a material composed of graphite (SP2) and diamond (SP3), boasts excellent self-lubricating properties of the graphite and high hardness of the diamond. Thus, it serves as an effective self-lubricating coating that enhances the surface performance of workpieces. Typically, the coating thickness ranges from 1 to 2 micrometers, with a surface hardness up to HV2500 and a low friction coefficient. Our company, based on the material, movement, and stress conditions of different workpieces, employs various processes to fabricate different types of DLC coatings using our proprietary PVD (Physical Vapor Deposition) method at low temperatures of 100 to 150 degrees Celsius, to cater to diverse materials and their processing and stress conditions.
Sewing machine parts such as the bobbin winder, needle bar, and balance components, among others, can all benefit from a surface treatment with DLC (diamond-like carbon) coating. This coating offers enhanced hardness, wear resistance, and self-lubrication properties, which can extend the lifespan by up to 5 to 10 times.
Especially, the diamond-like carbon (DLC) coatings produced by our company, with thicknesses ranging from 0.5 to 10 micrometers, have been widely applied. With stable processes and outstanding quality, our company has been mass-producing these coatings in mainland China for nearly 3 years. We have developed many types of DLC for specialized applications across various industries, including PCB milling drills DLC, oil-free sewing machine parts DLC, medical surgical instruments DLC, powder metallurgy mold DLC, speaker diaphragm DLC, automotive fuel injection system DLC coatings, and more. Our technology has already overcome the bottleneck of DLC industrialization faced by many domestic research institutions and coating manufacturers.

Sewing machine parts such as spinners, needle bars, and balance components, among others, which require rotational friction, can be coated with DLC (Diamond Like Carbon) for enhanced hardness, wear resistance, and self-lubrication. This coating can extend the lifespan up to 5 to 10 times.
