CMC History


CMC Group started its activity with the production of steel structures, in particular for die casting machines, ventilation units and parts for the automotive market.


At the end of the 70s, CMC Group begins shipment of the first products for the rail industry such as converter cases and battery charger cases for railway vehicles.

At the same time, it provides numerous soundproof cabins for generators. Countless steel bases are also produced. These are the supporting element of injection moulding machines for the production of plastic materials.


In the 90s, work with companies in the rail sector creates partnerships that lead to the creation of an office specializing in the design of railway components.

The products are designed and developed using CAD and calculated with programs that use the FEM method.

With this new structure and methodology, the goal to optimize the cost and quality of the finished product is reached.


The early 90s sees the beginning of the design and supply of cases for converters for ETR 460/470/480 (Pendolino) electric trains and electronic control for E652 locomotives.

Aluminum alloy cases for the inverter system for the Eurotram in Strasbourg are also developed and produced.

The need to reduce the weights for high speed structures leads the way to the design and prototyping of the aluminum alloy frame for the chopper inverter for the ETR 480 train, which uses rivets and structural adhesives as connecting elements for the first time.


Starting in 1996, aluminium alloy frames are produced for the inverters for the E412 locomotive and stainless steel cases for 35kW underbody converters for railway carriages.

The design, prototyping and manufacture of rames for E464 locomotive inverters begins and is accompanied by the development of the new roof for the same locomotive, which also uses rivet and structural adhesive technology.


In 2000 the company continues supplying roofs, battery charger cases, MV/LV conduit, HV ducta and converters for about 650 E464 locomotives.

Considerable numbers of cases for tramway air conditioning systems are designed and created, applying the then innovative rivet technology.

The production of roofs for locomotives is consolidated with the international supply of different versions of these products. The business of designing and supplying components for the pre-conditioning of aircraft begins for several international airports.


Starting in 2010, a new field develops for the creation and marketing of precision air conditioning systems for data centers (close control), aimed at the international market. CMC developed a complete range of solution as well as focused on special products and customized solution according to market and customer needs.

In the railway sector, production starts on aluminum alloy frames for the cabins and sills on the ETR1000 high-speed train and side walls and floor for metro.


New product lines of cooling system for technological containers and shelters are developed and supplied to important internation customers and end users.
In the airport field, the package for the pre-cooling odf the aircrafts during parking and for the telescopic bridges, is updated and improved.

In 2017 a re-organization process leads to a merger where CMC Rail s.r.l. has joined all the former companies of the group.
