Berl Stein, founder and president of NiCoForm (Rochester, N.Y.), is the Rochester Section of the American Chemical Society’s 2020 Entrepreneur of the Year. This award recognizes Stein’s development of innovative chemistry for the highly precise fabrication of metal parts with superior mechanical and chemical properties using electroforming, and his foundation of NiCoForm in 1999 to commercialize this breakthrough additive manufacturing technology. The society will recognize Stein at its Annual Awards Dinner on a to-be-determined 2021 date. This award and Stein’s impressive technical and business achievements highlight the continuing central role of chemistry in economic development.
Berl Stein was born in Chernivtsi, Ukraine and received his B.S. and M.S. in chemical engineering from the Moscow Institute of Fine Chemical Technology. He began his industrial career in metal-plating technology in 1977 at ElectronMach before later working at metal fabricator LegMach. In 1988, Stein moved to the U.S. and began his work in the field of electroforming, first at Servometer Corp. (Cedar Grove, N.J.) and then in Rochester, New York at Reflexite Corp.

Stein founded NiCoForm in the spring of 1999 with a single hand-me-down tank. Today, NiCoForm consists of 22 employees and occupies a much larger manufacturing space, where it prepares precision metal parts for a broad spectrum of demanding markets. Stein attributes his company’s success to continually improving its chemical and processing technologies to meet the ever-evolving needs of his diverse customers, especially in critical medical, aerospace, optical and other high-tech applications.
Stein and his first employee originally offered selective metal plating services for mold repair, learning throughout NiCoForm’s early years as they battled alloy properties and adhesion issues. Armed with a small conventional lathe, a single plating tank and a drive to gain customers, Stein and his team stuffed envelopes soliciting customers to try NiCoForm’s molds for catheters. Eventually, catheter-tipping dies became the company’s bread and butter, and it formed them day-in and day-out.
Shortly after, NiCoForm added a focus on making bellows while Berl continued to develop and optimize the chemistry for a proprietary nickel-cobalt electroforming technology. The resulting process, which strengthens the nickel and uses custom additive manufacturing technology, created the NiColoy alloy that is now the core of NiCoForm’s growing business. Even after several expansions, including the addition of computer numerical control (CNC) machining, inspection, chemical laboratory and office divisions, NiCoForm continues to develop advanced electroforming techniques for customers throughout North America, Europe, Asia and the Middle East.

NiCoForm continues to innovate with high-performance electroformed seamless bellows; catheter tip-forming dies; optical and microfluidic mold inserts; and the cost-effective fabrication of precision metal parts for use in laser, aerospace, medical and many other applications. The company focuses on continually improving its chemical and fabrication technologies for applications where its high-strength proprietary alloy can provide the greatest benefit to its customers and their products. With a “world-class alloy” and a diverse customer portfolio, NiCoForm is reported to be a world leader in nickel-cobalt electroforming and an important part of Rochester’s high-tech chemistry-based industrial infrastructure.
NiCoForm’s Rochester facility is built around Berl’s non-polluting recuperative rinsing concept. This technique sends no plating chemicals down the drain, saving valuable materials while protecting the environment.
A primer on this inexpensive and highly efficient process.
Masking is employed in most any metal finishing operation where only a specifically defined area of the surface of a part must be exposed to a process. Conversely, masking may be employed on a surface where treatment is either not required or must be avoided. This article covers the many aspects of masking for metal finishing, including applications, methods and the various types of masking employed.
