About Us

PEI was founded in 1967, specifically to provide the electronics and related industries with high precision chemically machined metal parts. Shortly after the company's establishment, PEI enhanced its capabilities by branching into the decorative market.

PEI utilizes a unique technology that provides precise tolerances to the electronics, medical, appliance, automotive and aerospace industries among others.

The company has grown from its original 4,000 sq. ft. in Holliston, Massachusetts, to its current 40,000 sq. ft. state-of-the-art facility in Milford, Massachusetts. Now considered a World Class manufacturer, PEI is noted for its innovative engineering, design and manufacturing methods and is driven by customer satisfaction and productivity.

Spirit Of Innovation

We were the first in the photo chemical etching industry to separate etching acids for iron and copper alloys, allowing the regeneration of all PEI acids for maximum uniformity of etching, controllability, predictability and environmental friendliness. This innovation also eliminates down time for unloading and reloading of etchant and makes costs and quality far more predictable and controllable. All of this translates into a better product at a better price for each PEI customer, whether that customer is purchasing precision parts, completed assemblies, step lids, RF shields, etc...

Customers will find significant advantages to working with PEI on prototype, short run or major production quantities. Our process, truly the ultimate blend of art and technology, results in no burrs, no stresses, no effect on magnetic properties, no deformation, no tool wear and the ability to machine to precise depths.

Our Mission

It is the policy of the company's executive management, while conforming to the company's long term objectives and requisite, statutory and safety regulations to provide and maintain a reliable and efficient service as well as satisfaction at the highest economic level to it's customers.
