Assembly (Canning) Cell

Purpose

To assemble the catalytic converter substrate with the support mat into a stainless steel tube ('canning').

Description

Several systems and methods are used to assemble the catalytic converter substrate with the support mat into a stainless steel tube (‘canning’). These systems vary from simple manually operated stations to fully automated assembly cells for high production. Due to the various methods of ‘canning’, Hess offers a wide variety of equipment to suit many different applications.

The patented Hess AGC gauging system provides a means to measure the stack-up of tolerances of the substrate and mat, and can provide ‘feed forward’ data for subsequent sizing.

The next assembly step uses the insertion station to push the substrate/mat assembly into the shell with a light fit to the specified axial position. Both single and dual end substrate insertion stations are available for this purpose.

The substrate and mat can then be assembled manually or placed in the automatic wrapping station for assembly with further sizing required to compress the shell and permanently hold the substrate in place. Alternatively, a substrate hard stuff system can used to insert the substrate into a pre-sized shell. An interference fit is created by feeding the substrate and mat assembly though a funnel to compress the mat material.
