Sheet Metal Marking Instrument | ERICHSEN Model 190

Purpose and Application Specimens made of ferrous and non-ferrous sheet metal and prepared with the ERICHSEN Sheet Metal Marking Instrument, Model 190, provides extensive information about their behaviour during subsequent deformation. The measuring grid applied to the specimen electro-chemically, indicates in all parts of the work piece the direction and magnitude of the strain produced. The degree of strain in the form of elongation or compression can be clearly seen by the distortion of the pattern of the measuring grid and can be measured numerically.

All types of sheet metal used in forming can be provided with marking. The electro-chemical application of a measuring grid takes a few seconds. If DC is used then 0.001 - 0.02 mm deep marking is obtained, whilst with AC clean forms and lines in black, brown or white are obtained on the sheet metal surface. With measuring grids with circles 5 mm diameter the strain in the material is shown up precisely, especially in the critical areas. The 0.1 mm thin, clean, uninterrupted lines obtained with our marking system and the dimensional consistency and regularity of the various marking grids provide a basis for a high accuracy in measurement. The marking rollers transfer the measuring grid from the precision stencils evenly and quickly onto small or large surfaces. Stencils with squares 2 mm (X02) for automatic analysis and also with circles 5 mm (X10) for manual analysis are available
