HVOF Coating Screw HVOF (High Velocity Oxygen Fuel) coating process is a kind of thermal spraying technique that melted (or heated) materials are sprayed into the surface. Technical Parameters Product Name: Full Coating WC Screw Material: JYG3 + Tungsten Carbide Alloy Coating Suitable Machine: Injection / Extrusion / Blowing ... Available Size : Φ14-80mm, L < 2,300mm Process Method: HVOF Spray Surface Hardness:1100-1400 HV Advantages By HVOF technology, alloy powder spraying is under high pressure and high velocity. The adhesive force is over 10000PSI, and the powder density can be achieved up to 99.8%, which offers outstanding performance in wear & corrosion resistance. Application Specially for Halogen-free material with below 65% glass fibre filling. -------------------------------------- Ningbo Jinyi Precision Machinery Co., Ltd.
