AMCO Engineering established in Chicago, Illinois to develop and build cabinets for amateur radio and HAM radio enthusiasts.

Buhrke Industries established as tool and die shop based in Chicago, Illinois. Buhrke Industries moved to its current location in Arlington Heights, Illinois in 1965, where the company developed a tool and engineering apprentice school to train workers. This school paved the way for a Tooling and Manufacturing Association (TMA) training center. The training center continues to train Buhrke-Olson employees and apprentices from other companies.

Buhrke Industries develops tooling to produce complex aluminum foil pans and TV dinner trays. The tooling completely blanked and formed the trays, and created curled edges, all in one stroke of a high-speed, automatic press. These aluminum foil pans became iconic as Americans enjoyed the convenience of TV dinners.
