Our History

Founded in 1988 by Anthony and Jeff Sleegers, Sle-Co Manufacturing has developed into a high volume, high precision plastic injection molder of full production automotive components. In more recent years we have integrated complex assembly of those molded components. Sle-Co Plastics Inc. currently operates out of a 55,000 square foot, full climate controlled facility, on Creamery Rd. located in London, Ontario. Over a span of 25 years, we have grown is size and complexity. In December of 2013 we purchased a building in St Thomas, Ontario to assist with our growth. Our future plans for Sle-Co Manufacturing include adding more production capacity by the summer of 2017.
