Hector Diaz-Stringel, Dwight Morgan and Marc Imbrogno join top leadership at the Highlands Heights, Ohio-based supplier of thermoset molding compounds and molded composites.

The Composites Group (Highlands Heights, Ohio), a leading supplier of thermoset molding compounds and manufacturer of composite components, has realigned its senior management organization, announced president and CEO Terry Morgan.

Hector Diaz-Stringel has been promoted to VP of manufacturing operations, and Dwight Morgan recently joined the company as VP of sales and marketing. In addition, company veteran Marc Imbrogno was promoted to the newly created position of corporate director, market/product development.

“Realigning the management structure was essential to realizing the potential of the three business units we’ve assembled to form The Composites Group,” says Terry Morgan. The Composites Group was created in 2010 through the combination of Premix Inc. (N. Kingsville, Ohio), Hadlock Plastics (Geneva, Ohio) and Quantum Composites (Bay City, Mich.). “We now can provide a wide range of composites solutions, from a superior portfolio of compounds to a breadth of molding technologies complemented by integrated secondary and finishing capabilities,” Morgan adds.

A native of Mexico, Diaz-Stringel has spent most of his career in the chemicals industry, serving in a progression of engineering, sales and marketing, and operational roles that led to his appointment as president and general manager of Rhein Chemie Corp. (Cardon, Ohio), a subsidiary of Lanxess Corp. (Pittsburgh, Pa.). He left Rhein Chemie in 2011 to become VP of sales and marketing for Chemical Associates Inc. (Copley, Ohio). He joined The Composites Group as corporate director of manufacturing operations in 2012. Diaz-Stringel holds a BS in chemical engineering and management from the Monterrey Institute of Technology and Higher Education (Monterrey, Mexico) and a MBA from Kent State University (Kent, Ohio).

Dwight Morgan began his career in plastics with M.A. Hanna Co. (Cleveland, Ohio), a predecessor to Avon Lake, Ohio-based PolyOne Corp, where he held a succession of corporate development and general management roles. In 1998, he left Hanna to form Accel Color Corp. (Naperville, Ill.), a producer of custom-formulated color and additive systems that grew to four facilities and $20 million (USD) in annual revenue. When Accel Color was sold to Techmer PM LLC (Clinton, Tenn.) in 2008, Morgan continued to run the company as a wholly owned subsidiary, joining Techmer’s senior management team. Morgan holds a BA from Kent State University’s School of Journalism, and a JD from the University of Akron School of Law  in Alron, Ohio, where he is a member of the bar.

With Premix for more than 14 years, Imbrogno has held various commercial positions, including account management, market management, sales management and business development. He began his career as an R&D chemist at Cleveland-based Glastic Corp. He subsequently joined chemical giant BASF (Florham, N.J.), where he held polymer product development and business development positions. He holds a BS in chemistry from the University of Akron. In this new position, Imbrogno will help align the company’s R&D efforts with market opportunities.
