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
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:
