About
Jeff Held owns and runs New Berlin Plastics, the custom injection molder whose name is also its hometown.
A CPA with years in public accounting and thermoset plastics distribution—including Upper Midwest business manager work at Ashland Distribution after helping sell a prior firm—he and Mark Siewert bought the company in July 2001 from founders William Aukofer and Robert Zeman.
The firm’s main plant is a roughly 100,000-square-foot New Berlin campus, and in 2022 it leased a second New Berlin building of about 93,700 square feet, roughly doubling footprint as employment climbed toward 165 people. The company molds and assembles components for OEMs across diversified industrial markets and keeps ISO 9001 certification current.
