Our History

John Michelon

My name is John Michelon, entrepreneur and owner of Cosmos Manufacturing Inc. In 1972, with one full-time employee and two apprentices, I established Cosmos Tool and Die in my garage. To meet the growing demand of my early customer base I purchased space in an industrial park and built a 3,000 square foot building, which is where Cosmos is located today.

As the company grew over the years I would build an addition onto the facility to ensure we had the capacity to fulfill our commitments. Today Cosmos is more than 30 times larger than it was in its early days and the number of employees has grown from less than a handful to upwards of 200 people.

As the company expanded, I realized we wouldn’t be successful if we only focused on die making. I decided on building my own product and selling it to OEM’s (Original Equipment Manufacturers). To signify this expanded offering I changed the name of the company from Cosmos Tool and Die to Cosmos Manufacturing.

Cosmos offers a complete package; we design and engineer products, build all of the tooling in house, stamp all of the components, weld, braze, black oxide, and anything else that is required to provide a completed assembly. We are also proud of the fact that our products are made exclusively in America, we do not produce offshore and import our products.
