Alco Manufacturing Corporation, LLC was founded in Elyria in 1971 when a small machine shop run by Elson Donovan and a partner began machining parts for the hydraulic market. They formed strategic partnerships in the Cleveland area—at the time, a strong economic environment for manufacturers—with Acme Gridley screw machines acting as the backbone of the company. Thanks to forward-thinking founders, hard-working staff and a strong culture, Alco quickly grew.

Alco Manufacturing Corp. LLC purchased Manth-Brownell in 2020.  The company was started by Mr. Vern Brownell in the early 1950’s, in a garage across the street from the company’s current location just outside of Syracuse, NY. In the late 1950’s, Mr. Brownell merged with Mr. Burton Manth of Trex Screw Products to form Manth Brownell. In 1962 they sold the company to the Skinner family, who owned the company up until the Alco acquisition.


The purchase of Manth provided Alco with a 5th location including two buildings totaling 135,000 sqft., over 140 employees and more than 175 pieces of equipment including: multiple spindle automatic screw machines such as Euroturns, Gildemeisters, Wickmans and Davenports, and CNC equipment including Swiss-type Citizens, Nakamura-Tome, Hyundai-Kia and Haas. Manth's customers are from a diverse range of industries and opens up new markets of expertise for Alco to expand and grow.

Alco Lakeshore was founded as Lakeshore Automatic Products, Inc. in 1980.
