Sheet Metal Shrinking and Stretching Machine
Originally developed for use in the aircraft industry on aluminum parts, the 1447-6DT is now widely used by the entire metal working industry because of its ability to:
- Remove wrinkles and fit sections normally formed in presses or drop hammers.
- Form rolled, extruded and formed angles and tees.
- Produce double curvatures from flat sheets.
The machine performs efficiently on most metals.
All models combine shrinking and stretching capabilities into one unit and provide the following advantages:
- Eliminates time consuming hand de-wrinkling and hammering operations.
- Eliminates expensive form blocks and special anvils.
- Increases work output and reduces operator fatigue.
- Eliminates use of special dies or presses in forming various shapes and contours on angles, tees and other sections.
- Cold-worked material results in higher material strengths.
The Model 1447-6DT(6-inch throat ), Model 1447-12 (12-inch throat) foot-operated, and Heavy Duty foot-operated Shrinker Model 187 (4-inch throat), ideal for short production runs and prototype work, requires little floor space in assembly or manufacturing areas.
For longer production runs, the ERCO Model 312BDT (12-inch throat), Model 306(6-inch throat), Model 476 (24-inch throat) Power Shrinker Stretcher is more effective.
