Applications

The Imprinting process according to DIN SPEC 4864 opens up new applications in the field of materials testing.
In the Production and incoming and outgoing goods it convinces by the fast and reliable determination of the mechanical properties.
In the Research and development it is used where the conventional methods of tensile testing and hardness testing do not offer a solution. Furthermore, the method opens up the possibility of performing an inline test or even a 100% test. This makes it possible to automate materials testing within the framework of Industry 4.0.

Production and goods receipt and issue

User report:
Testing of press-hardened sheet metal parts

Problem Statement:

  • Long waiting time due to tensile test in external laboratory
  • High testing costs
  • Local testing at small distances of 3-10 mm not possible

Solution by imprinting process:

  • Shortened development times due to fast and inexpensive material characterization
  • Strength determination at short intervals

Reliable incoming goods inspection

QA for small components

Comparison of testing costs

research and development

Case Study: Strength analysis of the edge zone

Problem Statement:

  • Determination of flow curves for the boundary layer only conditionally realizable
  • Upset test specimens with a case hardening depth of
    EHT = 3 mm must be realized.
  • Elaborate sample preparation

Solution by imprinting process:

  • Determination of flow curves directly in the edge zone of the tooth flank
  • Complicated manufacturing process of upsetting samples is no longer necessary

User report:
Local weld inspection

Problem Statement:

  • Hardness test only conditional statement on strength
  • No FEM simulation possible

Solution by imprinting process:

  • Determine Rp0.2 and Rm at defined distances in a weld seam
  • Data can be used for detailed FEM simulations
  • Optimization of the welding process

User report:
Material data for FEM in forming technology

Problem Statement:

  • Very small blanks, which cannot be characterized by compression or tensile tests.
  • Preliminary stages are used
  • The following forming and process steps are not considered

Solution by imprinting process:

  • Strength determination also on small components
  • Data can be used for detailed FEM simulations
  • Optimization of the forming processes
