美国Hammond Manufacturing公司成立于1917年，Hammond Manufacturing是专业生产变压器，电源的公司。产品广泛用于钢铁，能源化工，航空器材，铁路等行业。

Hammond Manufacturing始于1916年的一个后院工作室，位于加拿大安大略省的圭尔夫。 1917年，原公司称为O.S.Hammond和儿子在圭尔夫成立。 O.S. Hammond和Son在1919年至1927年间开始制造电子管收音机，电池充电器和其他相关产品。在1930年代早期，Hammond Manufacturing成为加拿大第一家制造一系列双柱机架和一个窄柜以支持不断增长的广播公司和通讯业。在1950年代和1960年代，各种电子产品的爆炸性需求为新产品和多样化创造了许多机会。在这些年里，Hammond Manufacturing成为变压器，机架和机柜以及电气和电子行业外壳的领先供应商。
 
在过去的四十年中，公司将重点放在美国和国际市场上。Hammond Manufacturing对变压器公司进行了多次战略性收购，并成为北美电气OEM市场最大的磁性供应商之一。它还与美国和欧洲公司建立了多个战略联盟，以扩大其已经广泛提供的外壳和相关配件。
 
2000年，Hammond变压器部门分离成为一家新的独立公司Hammond Power Solutions，Inc。（HPS）。 HPS生产定制和目录变压器及相关磁性元件。重组使两家公司能够独立实现其战略目标。 Hammond Manufacturing的核心产品继续作为电气和电子外壳，机架和机柜，电源杆和电子（低压）变压器。

Hammond Manufacturing has been operating for one-hundred years, with deep historical roots. The business started 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 2000, the Hammond Transformer Division, separated to become a new independent company, Hammond Power Solutions, Inc. (HPS). HPS 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 electronic (low-voltage) transformers.

Today, Hammond Manufacturing is a global company with customers worldwide. Our 675 plus team members work together to deliver on our promise of quality products and service excellence. High performance manufacturing equipment and continuous improvement management techniques combine to enhance our reputation for quality. Ongoing efforts to differentiate ourselves through high levels of service and customer satisfaction are a key corporate focus. These are the cornerstones to our future success.
