WAPATO — Amtech, a Lower Valley manufacturer of composite components, plans to expand its operations to the Southeast and Midwest by purchasing a similar manufacturing business in Alabama.

Amtech announced Thursday that it has acquired Arrowhead Composites and Thermoplastics in Elmore, Ala., a manufacturer of fiberglass components for the transportation, recreation and utility industries, according to a news release from Amtech. The price was not disclosed.

Arrowhead Composites and Thermoplastics was established in 1969, and in 1994 was purchased by Arrowhead Plastic Engineering, headquartered in Muncie, Ind. The 80,000-square-foot plant is 10 miles north of Montgomery, Ala., and serves customers in the Southeast and Midwest, the release said.

Amtech plans to improve and expand those markets, the release said.

“Through this strategic acquisition we can meet the demand of our regional production commitments and provide a new territory for growth,” Amtech CEO Doug Christie said in the release. “Arrowhead Composites and Thermoplastics’ stellar track record positions the company for continued success in the marketplace.”

Situated in a Wapato business park, Amtech was established in 1987 and manufactures an array of composite-based components, including Humvee tops and other body parts and armour for military vehicles. Amtech is owned by Blackford Capital, Grand Rapids, Mich.-based private equity firm. The company employs more than 100 workers.
