We work as a team at HN Precision and through our lean techniques; we are able to bring continuous improvement to our processes and organization. We strive to have the highest integrity as individuals and as a company so we can have full accountability for our end products.



HN Precision originally started as four independent precision machine component manufacturing companies with four different facilities located in Illinois and New York. These four companies were General Automation, Inc. which was founded in 1935; Gillette Machine & Tool which was founded in 1947; Helio Precision Products which was founded in 1984 and Nationwide Precision Products which was founded in 1965. For the last several years, these companies have been part of the Precision Partners Holding Company (PPHC) family. In 2011, we began the process of integration with the senior leadership being common between all four companies.



HN Precision strives to be our customer's end-to-end solutions provider for comprehensive project management from design to delivery. HN engineers work closely with the customer during the prototype development process, identifying opportunities to increase efficiency, cost savings and quality. Manufacturing engineers provide "design for manufacturability" improvements on initial design, where possible. In addition, our engineers design and manufacture specific tools and fixtures for the precision components.
