About ACAT



ACAT Global was formed in 2010 with the acquisition of General Motors-developed
catalytic converter substrate technology and related
production assets from Delphi. Senior Delphi engineers joined us at that time as well.

In 2012 we achieved ISO-9001 certification to signal and enable our
dedication to the highest quality standards and continuous improvement
in everything we do. We were recertified by NSF in September, 2015.
