About Us

Hillock Anodizing, Inc. was founded in 1969 by John J Hillock Sr. with a focus on Aluminum Anodizing, Hardcoat Anodize, Chromate Conversion Coatings and Passivation of Stainless Steel. From our humble beginnings in a small 2500 square feet building 40 plus years ago, we have grown to two locations totaling 38,000 square feet, in Northeast Philadelphia, with our emphasis still on the same coatings we started with, with the one addition being Electroless Nickel Plating.

We are a quality and service driven company that recognizes the urgent delivery and critical tolerance requirements to which your parts must be finished. Our Quality Committment is evidenced by our achievement of the prestigious NADCAP Accreditation ( National Aerospace and Defense Contractors Accreditation ), that only select Metal Finishers have achieved. In addition we have earned process approvals from numerous Aerospace, Defense, Medical and major Commercial and Industrial Manufacturers. We provide RoHS Compliant Coatings and we are ITAR Registered.

Hillock Anodizing is still owned and operated by second and third generation Hillock family and we proudly employ many employees with 25 to 30 plus year tenure that have shared and contributed immensely to our growth and business journey.

All of us at Hillock Anodizing will always service our customers with a committment to excellence. We will never forget the opportunity that all of our fine customers have given us and cherish the loyalty and friendships that have forged from these business relationships.

We welcome your questions, challenges and opportunities. You and your customers are always welcome to visit our plant for a Quality Audit, Plant Tour or to just stop in and say hello!
