Customized Testing Machines

Application

The mechanic shock test bench allows examining components and modules with shocks. The shocks imitate in a simple way the stress for example occurring  during transportation.

Features

• Acceleration at impact ca. 15 g
• Shock width ca. 10 ms
• Shock frequency ca. 1 Hz
• Max. test weight 50 kg

Application

The biaxial testing machine is an electro-mechanic testing machine to carry out uni- and biaxial tensile tests with normal test specimen or cross specimens according to ISO 16842. The testing machine makes it possible to generate independent loadings at cross-shaped specimens of metal in two axes orthogonal to one another. So, it is possible to simulate biaxial distortion conditions, for example occurring with typical sheet metal forming.

Features

The two orthogonal axes consist of two opposite single drives each.

• Nominal test force static: 100 kN in tension direction (dynamic up to 10 Hz), 10 kN in pressure direction
• Nominal test force dynamic: +10 kN (swelling in tension direction), 0.5 mm amplitude
• Nominal stroke: 150 mm for each drive (300 mm per axis)
• Test speed: 25 mm/s for each drive (50 mm/s for each axis)
• Special design with pressure test
• With precision force transducer and position measurement system as standard
• Mechanic specimen clamping with replaceable tensioning wedges
• High accuracy of the drive axes (angle fault tolerance 0.5° at maximum)
• 4-channel dynaSax-D3 control system
• Optionally with system and software for optic 3D and 2D measurement of local deformation of the specimens

Application

The PVR-400/400 rig serves to carry out a programed deformation-disruption-test. The PVR test was developed as a technological procedure to determine the susceptibility of disruption at high temperatures of basis material and filler metals with high quantitive validity concerning the influence of the component following Prokhorov’s theorem.

With a resurface welding on a plane specimen is overlaid with an increasing tension speed in welding direction with applying a tension force at the same time.

Features

• Nominal force tension: 550 kN (higher forces possible)
• Nominal force pressure: 950 kN
• Velocity-controlled tension movements up to 400 kN
• Welding arm adjustable in 3 axes
• Efficient measurement and evaluation together with computer controlling and a corresponding software

Application

The testing rig serves to determine the static torsion resistance and service life under variable load at assemblies of ceramic fused silica rolls/pipe ends with a metallic mating part.
The tests can be carried out with temperatures from room temperature to 300°C.

Characteristics

• Testing force: 10 kN
• The testing frequency is continuously adjustable between 0 and 20 Hz.
• Torque: static up to 1000 Nm, dynamic fatigue test up to 150 Nm
• The load is applied on the specimen by means of a diaphragm cylinder, generating torque at the specimen with a coupling rod.
• Flexibility: The clamping device can be easily exchanged and can be adapted to different roll sizes.
• Automatic test procedure: The static test is terminated as soon as a torque drop is detected or a certain torsion angle is exceeded (both termination criteria can be adjusted). The dynamic test is terminated as soon as a previously adjusted maximum number of load cycles is reached, or a maximum phase shift between applied moment and torsion angle is exceeded. It is not necessary to supervise or attend the test procedure permanently.
• Comfortable operation: Next to the machine, all display and operation elements (monitor, heating controller, cooling water controller etc.) are clearly arranged.

Application

The measurement machine for thickness DMP-15 was developed to measure plates out of plastic with the following qualities:

• Material thickness from 0.1 to 12 mm
• plane
• even
• clean
• not electrically charged

Features

• Measuring thickness at three points in linear way over the whole length of the plate
• Automatic feed and measuring the plate thickness
• Efficient measurement and evaluation with software
• Position of the outer sensing devices over the width of the plate freely eligible
