Electrodynamic testing machines

Our equipment for fatigue testing

When establishing INNOPROOF we have chosen electrodynamic testing machines that are on the cutting edge of technology. Due to the electromagnetic drive, the testing machines are operating nearly free of wear and are capable to realize high forces and frequencies.

Our 6 testing machines by TA Instruments/ Electroforce can apply forces up to +/- 7.5 kN with a frequency up to 100 Hz. For the lower force range additional electrodynamic testing machines were purchased from the manufacturer Instron.

Our 14 testing machines manufactured by Instron work with forces up to +/- 3.0 kN.
7 of these machines also have a torsion unit for combined load and motion profiles. With the torsion units up to 25 Nm of torque can be applied.

Equipment for fatigue testing of dental implants

Our machine for fatigue testing especially for dental implants per ISO 14801

With our Dyna5dent we can test up to five dental implants at the same time according to ISO 14801. Each station is controlled individually and different load levels can be driven under load control. Whether it is a Woehler curve or a stair step procedure, whether dry at room temperature or in saline solution at 37 ° C, we test under controlled conditions and with experienced and well-trained personnel. The force and temperature values ​​are continuously recorded during the tests. The test procedure according to ISO 14801 is listed in our accredited scope and the test reports are internationally valid based on the MRA-ILAC agreement.

Electromechanic testing machines

Our equipment for static testing

We are also equipped with two electromechanical testing machines from the manufacturer Zwick. Using these, compression and tension tests may be conducted in the range up to 5 kN or in the range up to 50 kN. At INNOPROOF, these machines are used for static testing of different implant types, e.g.

For torsional testing, a custom setup was developed.

Mammary implant fatigue testing

INNOPROOF is testing breast implants according to ISO 14607: 2018 Annex C.1 on four 12-station testing machines (up to 48 samples in parallel). Under a static load of 50 N, shear stresses are applied to the implants by means of an electrically driven moving plate over 6,500,000 cycles. The test benches operate with a frequency of 3.3 Hz, as required by the standard.


With our digital microscope from the manufacturer Keyence, we can produce images of the samples with optimum depth of field, e.g. before and after the tests. Depending on the lens selected, magnifications up to 200x or up to 5000x are possible. The 3D depth of field allows the consistently sharp display of arched samples or samples in an oblique view.
