ABSTRACT:
A catalytic converter is manufactured by wrapping a monolith core in an intumescent mat, surrounding the core and mat with a pre-wound metal jacket and compressing the jacket using tension bands. During compression the housing jacket is knocked at a frequency between 20 and 80 Hz to cause setting of the intumescent mat between the core and the jacket.
