A History of CPC

CPC Engineering Corporation started after World War II (in 1946).  CPC is based on the first initial of the owners’ last names: Charles P Chiaffone (C), Lloyd W. Pote (P), and John A. Cognetta (C).

 

They started as a weldment company – engineering and fabricating weldments at a time when they were not available from others.  They provided fabrications for customers in the machine tool, power generation, marine, defense, and high technology industries.
