PVD Coating Screw PVD (Physical vapor deposition) is characterized by a process in which the material goes from a condensed phase to a vapor phase and then back to a thin film condensed phase. We are using this technology on our Titanium nitride coated screws. Technical Parameters Product Name: TiN-Coating Screw Material: JYG3 + TiN Suitable Machine: Injection / Extrusion / Blowing ... Available Size: Φ14-80mm, L < 1,800mm Process Method: PVD Coating Surface Hardness: 2200-2500HV Advantages Physical vapour deposition coating is of high hardness and performance, which provide additional protection against abrasion & corrosion. Application Suitable for optical products & abrasive plastics processing. -------------------------------------- Ningbo Jinyi Precision Machinery Co., Ltd.
