MONTREAL – Representatives of five New Hampshire companies say connections they made at an aerospace trade show in Canada this week should lead to new orders and export opportunties.

State officials, including Gov. John Lynch and Department of Resources and Economic Development Commissioner George Bald, led a contingent to the Aero Montreal Global Supply Chain Summit, a gathering of companies from around the world that concluded Friday.

Companies that made the trip included Tech Resources of Milford, which employs about 30 people; Orion Wire in North Haverhill, which employs seven; Axenics in Nashua, which employs 40; EPTAM Plastics of Northfield, which employs 108 and Corfin Industries of Salem, which employs 80, according to a press release issued by the Division of Economic Development.

New Hampshire was the only New England state represented at the summit, said Christopher Way, the division’s interim director.

“It’s extremely beneficial for us and our companies, who are getting to meet with some prime contractors,” he said in a statement.
