BOSTON, Nov. 10, 2026 (GLOBE NEWSWIRE) — Innova Engineered Plastics, a trusted leader in heavy-gauge plastic enclosures and single-use components for medical device and other critical, highly regulated industries, proudly celebrates its 50th anniversary. The company was founded in 1976 as ThermoFab and became Innova Engineered Plastics in 2025 to reflect its expanded capabilities and platform. Innova marks half a century of manufacturing innovation with operations spanning three strategic locations; Boston, Massachusetts; San Diego, California; and Mexicali, Mexico.
“Fifty years ago, a small team set out to build enclosures for some of the earliest computer equipment on the market. Today, that same spirit of precision manufacturing and engineering expertise carries the Innova name forward into new markets, new capabilities, and new locations,” said Mark Rauenzahn, CEO of Innova Engineered Plastics. “This anniversary isn’t just about looking back at what we’ve built. It’s a reminder of how much further we intend to go.”
Five Decades in the Making
ThermoFab got its start by building enclosures for early computer equipment and over the decades expanded its capabilities. In 1985, the company added five-axis CNC machining for tooling and parts, along with in-house painting, which helped make it a market leader in heavy-gauge plastic enclosures for highly regulated industries.
In 2022, Culper Capital Partners acquired ThermoFab to support its next phase of growth and investment. Since then, the company has continued to broaden its plastics manufacturing capabilities and the range of solutions offered to customers.
In 2025, the company adopted the Innova Engineered Plastics name to reflect its broader capabilities and growing presence in the markets it serves. That same year, Innova opened its first facility in Mexicali, Mexico, adding production capacity and nearshoring options for customers. It also acquired PolyCraft Tech, adding cast urethane molding to its manufacturing portfolio.
Building on 50 Years of Excellence
What began as a single facility has grown into a six-site manufacturing network. In the U.S., Innova operates a design and innovation hub in Boston, Massachusetts, a specialized cast urethane center of excellence in San Diego, California, and a new warehouse in Calexico, California. In addition, three production facilities in Mexicali, Mexico, allowing customer programs to scale quickly.
Together, these sites form a vertically integrated manufacturing platform that supports the full production lifecycle, from design and prototyping through full-scale production and assembly. Customers get a single manufacturing partner across multiple stages of production, plus the flexibility and capacity to take on complex projects in the aerospace, defense, medical, and industrial markets.
“Our history gives us credibility, but our future is what excites me,” Rauenzahn added. “We’re investing in our people, our capacity, and our capabilities so that Innova is positioned to lead the industry for the next fifty years.”
Looking Ahead: Continued Growth and New Technologies
Innova enters its next 50 years focused on growth. The company continues to invest in new manufacturing technologies, expanded capacity, and the engineering talent needed to solve our customers’ toughest challenges. Innova is also exploring additional processes, materials, and automation that will help customers bring products to market faster.
As customer needs change, Innova will keep looking for opportunities to expand its footprint, add complementary capabilities, and strengthen its partnerships across the industries it serves, building on the same commitment to quality and craftsmanship that has defined the company since 1976.
