Definitions

  • the present invention relates to a system and a method for producing heat insulation structures for insulating heat generating components.
  • Heat insulating components for providing heat insulation for heat generating components such as catalytic converters play a key role in maintaining the functioning of the catalytic converters, but if the catalytic converters go below a given temperature they lose their functioning. Taking into account the number of vehicles in the world, the number of heat insulating components that must be produced in yearly basis is enormous.
  • a most common way of producing such heat insulating components is by dipping a forming mould into pulp containing fibers, applying vacuum to the forming mould so as to draw pulp through the permeable surface side leaving at least one outwardly facing ceramic fiber structure on the outer surface side of the forming mould. Finally, the outwardly facing ceramic fiber structure is release from the forming mould and dried in a drying station.
