Started in 1945 by Ermon F Ayer, HPI Manufacturing, Inc. was originally conceived of as a flexible Contract Manufacturing company. HPI is still located on its’ original site in Hamden, CT. The original building HPI occupied was a former organ manufacturing factory. HPI Manufacturing, Inc. supported outsourced manufacturing for industries throughout New England.

In 1961 HPI added Lloyd M. Ayer, Ermon’s son as General Manager. At this time, HPI expanded into more complex component design and manufacture. Its’ customer base expanded to cover the entire United States, servicing diverse markets including hardware, medical, and the early space program. In the 1984 Glenn and Kylle Ayer, the third generation of management, assumed the day to day operation of HPI Manufacturing, Inc. HPI has since expanded into international sales of component and services in many industries including petroleum and chemical refining, plant maintenance, medical components, electronics, and more. HPI still maintains a presence as a contractor and tool designer in its’ original field such as hardware and consumer items.


Today, HPI Manufacturing, Inc. occupies 40,000 square feet of modern manufacturing floor space. Our commitment is the same as it was over sixty years ago: To provide a unique combination of support services and components to our customers. HPI is dedicated to diverse core competencies; the company is constantly evolving, adapting new technologies, processes, and exploring new industries. This adaptive approach allows HPI to customize its’ processes to customer needs.
