Product Features

Diamond-like Carbon Coating Processing - Diamond-like Surface Treatment - Ningbo DLC Processing - Ningbo Diamond-like Processing DLC (Diamond-like Carbon), a material composed of graphite (SP2) and diamond (SP3), possesses excellent self-lubricating properties of graphite and high hardness of diamond, making it an ideal coating to enhance 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 produce different types of DLC coatings at low temperatures of 100 to 150 degrees using our proprietary PVD (Physical Vapor Deposition) method to accommodate different materials and processing conditions. Sewing machine accessories like bobbins, needle bars, and balance components, which require rotating and friction, can be coated with DLC (Diamond-like Carbon) for enhanced hardness, wear resistance, and self-lubrication, extending their lifespan by 5 to 10 times. Particularly, the DLC coatings produced by our company, ranging from 0.5 to 10 micrometers, have been widely used. With stable processes and outstanding quality, our company has been mass-producing in mainland China for nearly 3 years, developing various types of DLC for specialized applications across industries, such as 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, etc. Our technology has overcome the bottleneck of DLC industrialization faced by many domestic research institutions and coating manufacturers.
