Laboratory

Behind every detail we develop there is in fact extensive research work: new materials, new technological solutions, new production approaches. In all the applications we produce in which quality, reliability and sometimes safety impact play a primary role, Verification and Validation activities are as important and require as much effort as development.

 
 
 

Our Group has had its own Verification and Validation Center for many years, where teams of passionate and highly qualified professionals in testing and validation engineering, specialized in different areas of expertise, carry out their activities in sophisticated laboratories. Starting from the setting up of the DV/PV Design Verification & Product Validation test plan, to diagnosis and problem solving, and then product certification.

Our laboratories are equipped to simulate, through consolidated methodologies that follow the guidelines of the reference standards, any operating condition; each product is subjected to a qualification phase during which numerous tests are carried out: electromagnetic compatibility tests; electrical tests; mechanical tests, both static and dynamic; environmental and material tests. These are time-consuming and thorough procedures that produce excellent results.

 The execution of qualification tests takes place in different locations of the Group in an autonomous way, a necessary condition to provide customers with the complete know-how from design to validation, as well as clearly improving the time to market.

 
 
 
 
 
 
 
 

 
 

Headquarters

 

In the laboratory in Italy we have a wide and complete range of environmental conditioning systems such as 4 shaker vibration systems with climatic chambers, 8 climatic chambers, 3 thermal shock chambers, 2 salt spray chambers, 6 thermostatic chambers, advanced instrumentation for the execution of electrical and electromagnetic compatibility tests (required by international directives and specific test specifications of automotive manufacturers) and a metrology room recently equipped with a new automatic CMM machine.

The EMC quality requirements provided for by the regulations in force and by the specifications of the OEM customers are achieved with tests carried out in an anechoic chamber and, with the aid of full compliant instrumentation, tests of radiated and conducted emission according to CISPR25, tests of immunity to radiated electromagnetic field according to ISO 11452-2 and conducted with Bulk Current Injection method according to ISO 11452-4 are carried out.

 
 

With the aid of a compact anechoic chamber and a radio communications tester, products developed by MTA and equipped with wireless capabilities (Bluetooth and Wi-Fi) are subjected to pre-certification emission tests and the necessary diagnostic measurements via radio (OTA - Over The Air).

Tests of immunity to electrical transients on power and signal lines, in accordance with ISO 7637 and customer specifications, are performed on test benches fully equipped for this purpose.

The impact of ESD electrostatic discharge on devices is evaluated with immunity tests performed in accordance with ISO 10605 and variants introduced by the specific requirements of automotive manufacturers.

A specific test environment and a precision spectroradiometer allow the analysis of the photometric characteristics of dashboards and displays.

 
 
 
 
 
 
 
 

 
 

MTA Morocco

 

The new lab in MTA Morocco is equipped to do all electrical, mechanical and environmental testing for the power distribution units assembled on site and supplied directly to customers.

The instrumentation in Morocco is larger than that in Codogno to cope with the fact that the PDUs are increasingly important in size, more powerful, heavier and must be tested in greater numbers because of the higher levels of reliability required today.

Worth mentioning are the 2 600 l and 1000 l climatic chambers, a 1200 l salt spray test chamber, a thermal shock chamber, a 600 l chamber for vibrating system, a vibrating system with 22 kN slip table.

 
 
 
 
 
 

 
 

MTA Brasil

 

In MTA Brasil, the laboratory, which has been set up for several years now, has been updated during the many interventions carried out in 2020.

It is equipped with two climatic chambers from -70°C to +150°C; a 600-liter salt spray test chamber; a 350-liter chamber for thermal shocks from -70°C to -180°C, as well as numerous electrical and electronic equipment.

 
 
 
 

 
 

MTA China

 

The laboratory in China was set up as soon as the entire business moved to its current site. Since 2017, in a dedicated area, the main tests are carried out, such as those on dimensional, electrical, mechanical, environmental aspects, mainly aimed at quality tests of connectors and PDUs.

The laboratory is also equipped to cope with an expected increase in the product range that will be supplied from China to some important OEMs and that needs the guarantee of all the tests required by the customer.

In fact there are 2 environmental simulation systems: a climatic chamber compatible with the implementation of a vibrating system and a controlled ventilation oven; a SmartScope for dimensional measurements; a dynamometer; a nanovoltmeter; a digital oscilloscope; a melt flow tester.

 
 
 
 

 
 

MTA Slovakia

 

The laboratory in Slovakia, developed over the years in parallel with the growth of the site, ensures the control and continuous testing of production processes in particular of plastic molding and the necessary support for the periodic requalification of the product as well as the activity of problem solving.

It is equipped with basic equipment for the main mechanical and leak tests and a metrology room with optical measurement systems and profile projectors for dimensional measurements.
