HVOF Coat 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.

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.
