powder particles coming out spraying gun is up to 1200m/s , under the action of the heating energy , produced the enough high-density coatings of equivalent sintering. The maximum bond strength between the coatings and workpiece surface is up to 24kg/mm2 after impacted with the surface of workpiece.

wire&cable industry. wire drawing machine.

The guide pulley made of aluminum with enamelled equipment is easy deformation and the sprayed ceramic coating is failure because of its thin edge and light weight while being sprayed with ceramic rod gun by plasma sprayed facility.

Therefore , our company has introduced
