TRUMPF TruTool Fastening Seam Lockers

The use of fastening seam lockers is ideally applicable when joining sheet metal or other workpieces. The Tumpf TruTool Fastening Seam Lockers use power fasteners during a process known as clinching. The clinching process is a method where different pieces of sheet metal or metal plate are joined through tool cuts that are stripped into parts which provide a combined punching line and hence form a process. This creates a form fitting seam and the metal sheets systematically form hooks which hold tightly to one another. A permanent connection is produced and hence there is no need for any additional materials or even heat to produce a fixed closure.

High Quality Seams with TRUMPF Seam Locker

The TRUMPF Seam Locker Series is perfect for offering reliable and efficient sealing. Seam lockers are usually preloaded and are also nearly water and air tight. When bending takes place, three stages are involved; there are the thirty, seventy five and ninety degree angles created. The structure of the surface remains undamaged. The machine is automatically adapted to take up different thicknesses of the sheets.

The TRUMPF seam locker is made to lock and close Pittsburgh Seams which are self powered and also silent rolled in the gliding process. The preparation of this type of locker is usually done by the use of a stationary machine. It then forms the required edges needed in the sheet metal part. In the end, a vertical seam part is always placed onto the Pittsburgh seam which allows two or even more work pieces to be joined together into one piece.
