Benefits
- Continuous visualisation of cracks and deformations provides immediate results.
- Ensures durable and reliable products under real-use conditions.
- Cracks can be observed in one single bending operation.
- Durable construction guarantees a long service life.
- Ergonomic lever simplifies testing.
- Does not require calibration (no certificate).
- Cylindrical version also available.
How To Perform A Conical Mandrel Bend Test
The test is performed by bending the sample over the cone, determining the minimum diameter at which the coating:
- Begins to crack.
- Lose elasticity
- Or start to peel off.
This enables continuous and precise results in a single test.
Suitable Applications & Materials
Bending tests with mandrels are practical for analysing:
- Industrial coatings and paints on metal.
- Material development and control in labs.
- Products subjected to bending or mechanical deformation.
