Testing device for tensile tests (round specimen and flat specimen)
Testing devices for tensile tests with Flat samples are designed to clamp the sample parallel to the plane, centered and without slippage or bending stress.
For this purpose, the flat samples are placed in the flat sample holder using half-shell technology. This ensures simple and quick handling and reliable force transmission.
Testing devices in tensile testing for Round samples are designed to ensure axial and centric loading so that material properties such as modulus of elasticity, yield strength and tensile strength can be precisely determined.
The round samples are inserted into specially prepared sample adapters. This suitable holder ensures the test specimen is clamped in a centered position.
This ensures very good centering, minimal lateral force loading and repeatable alignment.
Test device for pressure tests
The central element of the test rig for compression tests are the pressure plates. These must be flat (very high flatness in the micrometer range) and possess high stiffness to minimize elastic deflection.
Furthermore, the plates are aligned parallel to each other in order to eliminate shear stresses.
Test device for 3-point bending test
The test device for the three-point bending test is used to test materials for properties such as bending strength, flexural modulus, fracture toughness or brittleness.
The bending device has two supports (lower rollers) and a central punch that transmits the force centrally, as well as a frame that fixes the support distance and ensures precise alignment of the rollers.
Test device for 4-point bending test
The test devices for the 4-point bending test are a further development of the 3-point bending test and are used when a more uniform bending stress is required inside the specimen.
The bending devices have two lower supports (support rollers) and two upper support rollers (load rollers), as well as rigid support frames that fix the support spacing and ensure precise alignment of the rollers.
Test fixtures for tensile, compressive, creep and cyclic tests according to ISO, DIN, ASTM, BS, etc. 1.200°C in air
The test fixtures, made of oxidation-resistant metal alloys, have a modular design and interchangeable sample adapters. Depending on the tensile load, sample geometry, and test type, the fixtures are individually designed. It is always ensured that they are optimally suited to our high-temperature furnaces, both spatially and structurally.
The pull rods vary in length depending on the type of testing machine and are generally equipped with an integrated spherical alignment mechanism. This enables precise specimen centering along the applied force axis and completely eliminates transverse bending moments in the specimen. The specimen adapters are manufactured in appropriate lengths so that different specimen sizes are always positioned at the same furnace height using the same high-temperature pull rod. This ensures that the high-temperature extensometer can always be positioned within the specimen testing zone.
The geometries of all sample holders are reduced to a minimum thermal mass in order to optimize thermal inertia during heating and cooling processes.
