The special feature of Model 146-60 & Model 146-100 are the increased drawing speeds of the drawing punch which, in addition to the normal drawing speed range that can be adjusted, in an infinitely variable manner and independent of load. This is achieved by using a separate oil circuit, fed by a pump with high volumetric displacement. Contrary to the high speed attachment based on a nitrogen accumulator, here a constant drawing speed behaviour is guaranteed over the total displacement of 150 mm. As to the technical design and the options available, including PC control and proportional valve technique, this machines are similar to Models 145.

Electronically controlled cupping test machine with electro-hydraulic drive and automatic test sequence, including crack detection, standardized cupping speed and a maximum drawing force of 45 kN – This testing machine is available as a work-top model with compact dimensions which requires only a minimum of space. For the ERICHSEN CUPPING TEST on all ferrous and non-ferrous metals in accordance with the following standards: ISO 8490 DIN 50 101 / 50 102 EN 14-58 ASTM 643-84 EN 14-67 JIS Z-2247
The Model 126 Plus ear measuring instrument is used to make axial measurements of deep-draw cups and can blanks. The typical standards here are DIN EN 1669 and ISO 11531. The device consists of a rotary table, a jaw chuck and a vertical measuring head (with measuring roller and length measuring probe). A jaw chuck secures and centers the cup. The measuring head can be adjusted to fit different sample diameters and heights. During one revolution of the rotary table, the measuring head records the shape of the cup edge (the so-called unevenness). Ear measuring instrument, for cups of 15 – 50 mm diameter, max. 100 mm cup height
The Bead Test Instrument Model 227, enables the quantitative assessment of the technological properties of stamping paints and plastic coatings on cylindrical standard cups. The instrument was designed to produce stresses comparable to those which occur in practice and is particularly suited for use in the development of high quality stamping paints
With electro-hydraulic drive and fully automatic test sequence. ERICHSEN Cupping Test, Deep Drawing Cup Test, Bore Expanding Test, Data Evalution Software with User Test Software, Data logger for recording the measurements such as drawing and blank holder force and stroke. This Sheet Metal Testing Machine is intended for testing materials in the medium thickness range (0.1 to approx. 3.5 mm). It provides rapid an reliable quality monitoring for sheet metal producers and users.
The ERICHSEN Sheet Metal Testing Machine, Model 100, is a bench mounted unit with a cast iron machine body and a cylindrical test head. To conduct the cupping test the sheet metal specimen or foil is entered into an opening through the test head. The screw-in blankholder is set for the sheet thickness using the scale provided. The test head is then tightened manually against a stop on the locating sleeve. This clamps the blank with a force of 10 kN as required by the cupping test standards mentioned above. The clutch pin is pulled outwards from the locating sleeve, the test head is turned clockwise and the cupping process commences. The cupping test value reached is displayed on a digital counter. The forming process and the appearance of the crack can be observed conveniently looking down onto the blank holder.
