Diamond Like Carbon Coating Processing Manufacturer - DLC Processing - Dongguan DLC Processing - What Are the Effects of Vacuum Coating?
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 to enhance the surface performance of workpieces, typically with a thickness ranging from 1 to 2 micrometers. The surface hardness can reach up to HV2500, and it features a low coefficient of friction. 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 different materials and their processing and stress conditions.
Sewing machine accessories such as swifts, needle bars, and balance components, among others—any parts that require rotating and friction—can be coated with DLC (Diamond-like Carbon) for enhanced hardness, wear resistance, and self-lubrication, resulting in a lifespan that can be up to 5 to 10 times longer.
Especially our company's diamond-like carbon (DLC) coatings, ranging from 0.5 to 10 micrometers, have been widely used. With stable processes and outstanding quality, our company has been mass-producing DLC coatings in mainland China for nearly 3 years. We have developed many types of DLC for specialized applications across various industries, including PCB milling drill bits 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 that many domestic research institutions and coating manufacturers are facing.
