Erichsen Universal Sheet Metal Testing Machine
Model 212
When manufacturing deep-drawn products the ingoing material is deformed in all three co-ordinating planes.
Thereby the surface coating should not become defect to avoid subsequent corrosion. For the standard controls
and proofs required for the purposes of quality assurance Model 212 is particularly suitable to conduct
cupping and deep-drawing cup tests within the sheet metal thickness range of 0.1 mm to 3.0 mm.
To intensify the tests by further special investigations, it is possible to carry out without any problem a redraw (a
second deep-drawing operation conducted on the standard cup using a smaller drawing die and drawing punch).
Key Features
Matched test tools permit automatic sequence of operations:
- pressing the test piece
- cutting the blank
- exerting the sheet holder pressure
- deep drawing
- sheet holder pressure release
- stripping of cup
- return of punch to initial position and switch-off of machine
