Kosmo Machine Inc., a precision machine shop in eastern Henrico County, is investing $1 million and adding more than 30 jobs to increase production at its plant near Richmond International Airport. The company, founded in 1976, manufactures precision-made components for customers in industries such as electric power generation, electric motor components, shipbuilding and chemicals and fibers. Gov. Terry McAuliffe’s office announced the company’s expansion plans on Thursday and said the Virginia Economic Development Partnership will provide support for employee training.
