Quality Control:

IMMG S.A. operates under a quality assurance system that includes both the laboratory and the industrial part of the company. This system has been certified to be in compliance with the ISO 9001: 2000 and the EN 45001 (ISO/IEC 17025) Quality Standard by the Greek National Council for Accreditation (ESYD).

Electrical and electronic devices design - manufacturing, especially for the testing machines.

These devices include:

  • Analogue circuits for sensor and transducer interfacing (for strain gauges, load cells, pressure transducers, LVDTs, Hall effect sensors, thermocouples, cryogenic temperature sensors).
  • Galvanic isolators for analogue signal measurement and driving power circuits.
  • Digital interfaces for measurement and automation (incremental linear and rotary encoders, remote controls, analogue multiplexers for large input count).
  • Power circuits (On/Off, PWM furnace controls, PWM for motors, high voltage linear and PWM servoamplifiers for driving piezoelectric actuators).


case study DIRIS PANELThe DIRIS architecture – (DIrectional, Reinforced, Integrated, Stretched, Single yarn), European Patent 08386002, was applied to manufacture and test a carbon fibre reinforced PEEK panel simulating a spacecraft basement. The project was supported by ESA (2008). The DIRIS core and panel exhibit the highest strength in shear and tension in in-plane and out-of-plane loading. 





case study1

Design – Construction of 36 CFRP platforms (2004) for mounting and aligning optical and muon detectors of the CMS Experiment at CERN, Geneva.

These carbon fiber reinforced epoxy structures consist of hollow square tubes (made by pultrusion) and plates, precisely machined and bonded (60 µ m thickness) with an exceptional assembly precision. The dimensions were 4 X 1,8 X 0,05 m, the maximum flatness and alignment tolerance was less than 0.03 mm/m and stiffness in the order of 115 GPa.

case study2The Pole Measuring Machine (2000) was designed and constructed for CERN. A large, robotic, traveling, 5-axis machine for testing superconducting magnetic coils, 16 meters long. The two loading machines generate combined loading (up to 480 Tons), including bending. They composed of more than 2000 precisely machined parts, 45 sensors and a control cabinet with specially developed hardware and software. The critical components of the machines were optimized using suitable numerical techniques (including FEA).

case study3

Construction of an optical control unit for the LEOPARD II Main Battle Tank.
The unit consists of a trapezoidal shell (500 x 400 x 300 mm) of a complex shape and many parts inside made of materials ranging from cast aluminum to cast stainless steels and tungsten. The achieved dimensional and forms accuracies are in the order of 20 µ m / 400 mm and for a few parts even less.
