Lacquer and Paint Testing Machine

Model 212

Fully automatic cupping and deep-drawing cup test machine Model 212 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 and a maximum drawing force of 120 kN. The machine is operated via a resistive touch panel. The operation is simplified by the user-friendly menu navigation. Main and emergency Off switches are located next to the touch panel. The setting of sheet holding force and forming speed is carried out by ergonomically placed control buttons on the front of the housing.

Application: When manufacturing deep-drawn products the ingoing material is deformed in all three coordinating 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). Furthermore, the Bead Test Instrument, Model 227, can be used to form a bead into the cylindrical wall of a standard cup until a mechanic destruction of the coating is achieved. This is another possibility to intensify the test. The above mentioned sheet thickness range of 0.1 mm to 3.0 mm is based on material with a tensile strength of 400 N/mm². In case of a higher/lower tensile strength the values mentioned concerning the maximum sheet thickness that can be drawn, are to be reduced/increased.

Purpose: The following reasons are important for using the Cupping and Deep-drawing Cup Test Machine, Model 212, for quality assurance, research and development:

  • Lowering of the reject rate by concerted monitoring of
    the coating quality during production or in the process
    department.
  • Immediate sorting out of lower quality arriving at the
    goods inwards department by means of the ERICHSEN
    cupping test or the deep-drawing cup test. Without
    special test preparations it is possible to establish, if
    the material supplied corresponds to the prescribed
    properties.
  • The sturdy construction and hydraulic operation
    ensure a wear-resistant functioning of the machine so
    that high accuracy of the test results at low main-
    tenance and working expenses is guaranteed.
