Davis-Standard bought by Canada’s Onex Corp.

Extrusion equipment supplier Davis-Standard LLC now has Canadian-based ownership.

Private equity firm Hamilton Robinson Capital Partners has sold Pawcatuck, Conn.-based Davis-Standard to ONCAP, the middle market investing platform of Toronto’s Onex Corporation.

The terms of the deal have not been disclosed.

Hamilton Robinson, headquartered in Stamford, Conn., acquired Davis-Standard in 2003 and – according to a press release – has grown the company’s revenue from US$30 million to over US$300 million. “This revenue growth was accomplished through management’s execution on strategic acquisitions, lean manufacturing, global sourcing, enhanced technical capabilities and penetration of new markets,” the release said.

For Onex, the purchase is the latest in a line of plastics holdings, chief among them Husky Injection Molding Systems. Onex bought Husky in December 2007 and sold it last year to Berkshire Partners LLC and Omers Private Equity Inc.
