Metval is specialized in thermal spraying anti mechanical wear coatings for the automotive, valves, textile, pumps and drawing industries.

Such coatings are obtained with the following processes: wire metallization, air plasma spraying, HVOF and electric arc.
Examples of common applications in these industries are the following:

  • automotive: molybdenum coating on synchronizer rings, differential pins, gear box bushings and forks; bronze coating on forks.
  • valves: metal to metal seal with tungsten carbide TCC, chromium carbide CCC or metals coatings.
  • textile: plasma sprayed ceramic coatings on cylinders, feed rolls, thread guides.
  • pumps: plasma and HVOF coatings on bushings, pistons, rings, pumps shell.
  • wire drawing: plasma and HVOF coating on rolls, rings and cones.

Thermal spraying coatings are also utilized with other purposes:

  • to prevent corrosion;
  • for electrical insulation or conductivity;
  • as thermal barriers;
  • to restore original dimensions.

Machining and surface finishing operations (coating grinding, polishing, lapping) eventually requested by customers are carried out internally.
