The laboratory is a functional space designed around people and their work. The purpose of the area is to make available a larger, more functional space for lab testing, giving a more modern set up and layout, so as to optimize work quality and the time taken for individual activities. The large surface area available has been divided into separate bays dedicated to the different types of tests, each with the required specific equipment. These areas have been arranged so as to provide a rational work flow for our engineers to perform the required tests in an orderly fashion and without loss of time.
The electronic testing area within MTA’s laboratory is equipped with a 4 x 6 x 3 m semi-anechoic chamber, which is used to perform electromagnetic compatibility tests, including radiated emissions and immunity, on developed products as required by the prevailing laws and by the general supply conditions set by OEM customers.
MTA's laboratory can carry out ESD immunity tests in order to ensure the adequate protection of its electrical and electronics products in compliance with ISO 10605:2008 standard and with customer general supply conditions.
Thanks to a luminance and colour measuring camera, MTA’s lab engineers are able to carry out photometric analyses on instrument clusters and displays.
The laboratory has 12 climatic chambers that reproduce the climatic cycles required by the international standards and the main OEM technical specifications, with completely automated tests.
The MTA vibration test bench range includes 4 electrodynamic shakers for sine, random, sine on random and shock vibration tests. All vibration tests can be performed in climatic chambers set up for this purpose. One of the 4 shakers is connected to a slip table that allows stressing the sample on axis "Z" and physically rotating it to test it on axes "X" and "Y". Besides this, the sample is stressed on the two remaining horizontal axes thus keeping it in its actual orientation on the vehicle. The connected controllers feature multi-channel inputs and stroboscopic lamps allow a fast display of resonance frequencies of the devices under test (DUT) without using accelerometers.
MTA metrology lab currently has two contrast optical measurement systems with magnification power from 30 to 130x.
A Coordinate Measuring Machine (CMM) allows geometric checks and measurements, besides the standard size measurements.
The metrology lab also features X-ray equipment for thickness measurement of galvanic coatings on metal parts, a light cabin and a 63x optical microscope.
As far as the electromechanical components are concerned, the MTA lab features 4 DC supply units with double linear regulation to check the currently produced fuse melt time and resistance to variable stress. A user-friendly programming interface allows importing measurements from an oscilloscope and progressively stressing components for a preset number of cycles. Meanwhile, a data acquisition system allows detecting temperature and voltage of samples so as to directly compare and analyse the results. The lab equipment range is topped with 6 other power supply units, more than 50 stand-alone and programmable channels for electronic loads, 2 precision, two-channel power supply units, 6 multichannel DAQ systems with up to 20 multi-purpose channels, 2 milliohmmeters, 2 HV equipment of up to 40 kV and 3 ATE benches to perform complex electrical tests and life tests.
The MTA mechanical test room has a dyno station with exchangeable loading cells that can perform all traction and/or compression tests on components and raw materials. The software allows managing cyclic tests to check wear and fatigue of components such as mobile electric drives as well as electromechanical drives in general. Further to the above, there are 4 digital, portable dynamometers, ergometers with press and 200 N full-scale, flexible and portable instruments that allow applying forces on the DUTs simulating the line operator and providing, at the same time, the dynamic measurement of the applied load.
In compliance with the automotive specific standards, MTA stores a wide range of vehicle typical fluids to be used in the finished products inside the exhaust hoods to check the product correct operation in case of accidental contacts. Having different types of reagents allows checking product stress and/or manufacturing faults. The MTA lab makes use of 2 climatic chambers to perform accelerated corrosion tests in static and dynamic salt atmosphere. For tests and analyses on thermoplastic parts, MTA has a melt flow tester, a DSC and a muffle furnace specific for ash content measurements.
