UNIROLLS delivers thermal coated rolls with the highest quality of HVOF/HVAF surfacing solutions to prolong the lifetime and improve the quality of your processing rolls.
Additional post-treatment sealing, oxide layering, and polymer-based enhancements can be applied to further improve thermal spray roll coating performance.
PRODUCTION PROCESS
HVOF is a thermal spray process utilising the combustion of gases, such as hydrogen, methane, propane, propylene, acetylene, natural gas or liquid fuels such as ethanol or kerosene.
Fuel and oxygen atomise and mix within the combustion area. This mixture is ignited at controlled temperatures and pressures resulting in a flame with supersonic velocity.
Material is injected into the flame and propelled towards the substrate to form the coating.
