Gemini Group is a leading supplier of engineered plastic and metal products. With 17 locations in the United States and Mexico we are positioned to respond to the demands of our progressive customer base. Interrelated processes and collaborative engineering afford us the flexibility to avoid a one-size-fits-all approach to component and assembly manufacturing.

Our Heritage

The Plastics Segment. The formation of Gemini Group began in 1972, when Gemini Plastics was established in Ubly, Michigan. At first, Gemini Plastics only specialized in seat belt sewing and seat belt boot blow molding. As customers’ cut and sew operations began moving to Mexico, Gemini pursued additional opportunities to serve the automotive seating market which led to a new profile extrusion operation (Sierra Plastics).

During the next two decades, Gemini’s plastics segment continued to grow through the acquisition of an injection molding company (Thumb Plastics, Inc.), creation of a blow molding company (Regency Plastics) and the development of an interior trim manufacturing operation (Valley Enterprises).

The Metals Side of Things. In 1979, Gemini partnered with a precision machining company (CKS Precision Machining & Briney Tooling Systems) and a year later added a full service production machining operation (Axly Production Machining), in doing so, a metals segment was forged. In 1998, the metals segment continued to expand with the addition of an aluminum extrusion die company (Thumb Tool & Engineering).

Gemini Group is Formed. Each company operated individually until 1996, at which time this diverse group of plastics and metals entities were joined under one parent company, Gemini Group, Inc. Since that time, Gemini Group has developed into a highly successful, multi-industry enterprise recognized for our industry expertise, extensive manufacturing footprint, and commitment to continuous improvement.

Recent History. In 2011, in order to keep pace with the southern migration of automotive assembly, Gemini Plastics opened a sister plant in Saltillo, Mexico: Gemini Plastics de Mexico (profile extrusion).

The metals segment continued to expand its capabilities as well as geographic reach in 2013 with the additions of Mid-South Extrusion Die (aluminum extrusion tooling), Central Extrusion Die (aluminum extrusion tooling), and Consolidated Tool (die cast tooling). This partnership positioned Gemini Group as the title of second largest producer of aluminum extrusion dies and tooling in North America.

Today. Gemini Group is the largest employer in Huron County, Michigan, where we operate four plastic plants and three metal plants. Our manufacturing plants in Muscle Shoals, Alabama, El Paso, Texas, and Saltillo, Mexico are positioned to serve our customers in the Southern U.S. and Mexico.
