Application examples
The Imprinting process according to DIN SPEC 4864 enables the mechanical properties to be determined quickly and reliably, either as a substitute for or in addition to the tensile test or conventional hardness test.
The typical applications are in inspection and quality assurance
- during the inspection during production
- for local tests, e.g. after heat treatment or for weld seam tests
- in incoming and outgoing goods for fast and reliable determination of the material quality
- in the fast and close to production 100% inspection
- as well as other testing tasks which cannot be solved by the tensile test due to the necessary specimen size, speed, etc. the tensile test are not solvable
The main advantages in all applications are the fast, flexible and low-destructive testing of components, specimens and semi-finished products.
Production / Goods receipt / Goods issue
Example 1:
Testing of press-hardened sheet metal parts
Challenges:
- 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
Local / Punctual mechanical properties
Example 4:
Strength analysis of 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
Example 5:
Local weld inspection
Problem Statement:
- Hardness test only conditional statement on strength
- No FEM simulation possible
Solution by imprinting process:
- Determine yield stressYSand ultimate tensil strength UTS at defined distances in a weld seam
- Data can be used for detailed FEM simulations
- Optimization of the welding process
Example 6:
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
