Hammond started manufacturing in a backyard workshop in 1916 located in Guelph, Ontario, Canada. In 1917, the original company known as O.S. Hammond and Son was established in Guelph. O.S. Hammond and Son began making tube radio sets, battery chargers and other related products between 1919 and 1927. In the early 1930’s Hammond became the first company in Canada to manufacture a line of 2-post racks and a narrow cabinet to support the growing broadcast and communications industries. The explosive demand for electrical products of all kinds during the 1950's and 1960's created many opportunities for new products and diversification. During these years Hammond became a leading supplier of transformers, racks and cabinets as well as enclosures for the electrical and electronic industries.
Through the last four decades, the Company expanded its focus on the U.S. and International markets. Hammond made a number of strategic acquisitions of transformer companies and became one of the largest suppliers of magnetics to the North American electrical OEM market. It has also formed several strategic alliances with U.S. and European companies to broaden its already extensive offering of enclosures and related accessories.
In the beginning of 2001, the Hammond Transformer Division, separated to become a new independent company, Hammond Power Solutions, Inc. (HPSI). HPSI manufactures custom and catalog transformers and related magnetics. The reorganization enabled both companies to pursue their strategic goals independently. The core products for Hammond Manufacturing continue as electrical and electronic enclosures, racks and cabinets, power bars and transformers.
Today, Hammond Manufacturing is a global company with customers worldwide and is a publicly traded company on the TMX (HMM.A) and is headquartered in Guelph, Ontario, Canada. Hammond has offices around the World, including facilities in Canada, USA, UK and Taiwan. Hammond offers a broad range of standard products, modification services and technical support to electrical and electronic manufacturers, utilities and institutions through a global network of agents and distributors.
