Facility description

The i7™ I.D. spray gun delivers high performance cemented carbide, metal, and metal alloy coatings for internal diameter applications.
WC-based coatings with hardness of up to 1550 HV300
Variable nozzle configuration permits spraying of internal diameters as small as 120 mm
Coating porosity typically below 1%
Compressive residual stresses in coatings
Negligible oxide content in coatings (1.5-2 times that of feed stock material)
Durable and dependable in operation, the i7 requires minimal maintenance and is ideal for large scale applications.
The i7™ I.D. spray gun operates on Propylene or Propane. Highly efficient 100% air cooling eliminates the need for a chilled water supply.
