About Us


JCM  is a leading manufacturer of complex machined parts and assemblies for the aerospace, commercial, defense and medical industries. JCM is a privately owned corporation that is based in Ontario, California.  From its 140,000 square foot state-of-the-art facility, the company employs nearly 110 associates and hosts more than 70 of the industry’s most innovative CNC machines and technologies.

JCM was founded in 1978 by Jose A. Moyano and son Carlo Moyano. As immigrants from Argentina, their goal was to live the American dream – so they started their own business out of their garage. While doing business out of this garage, JCM obtained their first contract manufacturing parts for the Space Shuttle Columbia. Through an untiring work ethic and diligent goal setting, JCM has evolved into one of the most reputable world class leaders in the aerospace, defense, and medical industries that exist today.
