Precision Etching & Decorative Etching

Photofabrication Engineering, Inc. (PEI) was established in October 1968 in order to supply the fast-growing semiconductor and computer peripheral manufacturers in the Boston area with metal precision parts quickly and inexpensively. With the photochemical machining (PCM) process, the tooling needed to produce precision parts is essentially a low-cost, easily produced film that allows companies to move quickly through the product development cycle. The company is focused on providing the highest level of quality, and their state-of-the-art facility is dedicated to the PCM process.

PEI’s Precision Products Division manufactures mission-critical parts for most technology-driven industries. The company etches almost all metals, including Stainless Steel, Copper, Brass, Kovar, Sterling Silver, Beryllium Copper, Nickel Silver, Titanium, Zirconium, and other standard and specialty metals and alloys. PEI is also an industry leader in Titanium etching for a wide variety of applications, including medical implants and fuel cells.

PEI’s Decorative Products Division manufactures custom Brass ornaments, collectibles, and other items for museum stores, foundations, large and small non-profits, universities, and companies looking to recognize their customers and/or employees.
