AO-Presses Our high pressure pressing systems have pressing forces as high as 9 tons, and are one of the few automatic pressing systems on the market. With multiple types of feed systems like track-fed and drop-tubes, these pressing heads are built on a heavy C-shaped frame construction with an air-oil intensifier cylinder. The transfer escapement inserts one piecepart at a time into the jaws and the head simultaneously places and presses in one stroke. There is a built-in sensor that indicates the proper insertion to complete the pressing cycle. These systems add speed and efficiency to your pressing application all while insuring precision.
