Tradesman Manufacturing of Calgary, Alberta, was the first
purchaser of a new, patent-pending spiral-elbow duct machine made by Korean firm
Jinwoong Technology Ltd.
The Canadian company purchased the
machine in June from Standard Sheet Metal Machinery of Cedar Rapids, Iowa.
The
machine continuously produces spiral elbows from coil at speeds up to 18
seconds per piece. The elbows’ center-line radius can be modified through the
machine’s touch-screen controls. Straight duct portions of 2 inches and longer
can be made on the elbows’ ends, company officials say.
The
machine was to be installed at Tradesman’s factory in August or September.
