Universal Sheet Metal Testing Machine, Model 212

Fully automatic cupping and deep-drawing cup test machine for testing the ductility of coated, ferrous and non-ferrous metals (e. g. stamping paints, lacquered, plastic coated or electroplated materials). The testing machine is provided with an electro-hydraulic drive, a maximum drawing force of 100 kN as well as digital displays indicating the drawing force, the blank holding force and the drawing punch displacement.

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

Standards

  • ISO 1520
  • DIN EN ISO 1520
  • SIS 1841 77
  • BS 3900:E4
  • NF T 30-019
