We have been designing and manufacturing cabinets and components for energy distribution since 1964.
Thanks to the diversification of our plants and the opening towards technological innovations, we have made a name for ourselves not only in the compression moulding of thermosetting resins but also in the manufacturing and marketing of custom-made metal cabinets, containers, cabinets, switchboards and accessories for the installation engineering industry and energy distribution ENEL-approved systems.
Our catalogue provides a wide range of articles not only for electrical and electronic installation systems, but also for the manufacturing, automotive and alternative energy industries.
We also handle large-scale orders efficiently and with the top quality standards; we are able to manufacture complex geometries, (even non-uniform) diversified thicknesses and customised surface finishes. The same quality level is also provided in the services offered to the customer, from product design to prototyping, up to the development of moulds and consultancy on the chemical-physical properties of materials.
The compression moulding method enables us to produce various types of containers, switchboards and components with physical and mechanical specifications that are particularly suitable for the distribution of electrical power.

Technology in our sector allows us to achieve complexity and productive performance that were once unthought-of. The current technological level is the result of skills and expertise acquired in the use of alternative processes in the following manufacturing sectors:

  • Compression moulding
  • Injection moulding
  • Pultrusion

Compression moulding

Compression moulding is a moulding method where the (generally composite) material, (thermosetting resin loaded with glass fibres) made in sheets (SMC), is introduced inside paired moulds. The mould is then closed with very high force by vertical presses.
The material, thereby pressurized, adheres to all the parts of the mould, while temperature and pressure are maintained until the material has hardened.

The main advantage of this technique is that it enables producing even complex-shaped parts in a short time. From the moulding process it is possible to directly obtain even non-uniform thicknesses, stripes, studs, flanges, holes, etc., also arranged for metal inserts, so as to eliminate a series of subsequent operations. This process is particularly suitable for high volume parts made of composite materials.
Even today, this technology is most widely used in the production of boxes, switchboards and components with high physical and mechanical characteristics for the electrical energy distribution sector, as well as for the automotive industry, such as bumpers.


Injection moulding

Injection moulding from powder or granules is the most common technology for the transformation of thermoplastic materials. From a hopper the material moves into a heated chamber where it softens. It is then pushed into a mould by a piston or screw. The pressure is maintained until the mass has hardened sufficiently to be extracted from the mould.
This way variously-shaped and –sized parts are produced discontinuously, weighing between a few grams and several kilos.

The main advantages of this technology are:

  • the possibility of producing parts characterized by complex geometries
  • high productivity
  • low production costs
  • high process automation
  • the possibility of producing small-sized parts
  • moulds and presses can be used with different plastic materials
  • the possibility of pressing/moulding in combination with metal inserts
  • production of pieces with different colours and materials


Co-moulding is the technique that enables parts made from different materials, such as (thermoplastic or thermosetting) resins and metals, to be moulded in a single solution. Its most common applications are comoulding with metal inserts and connectors for electronics.


Metal cabinets

Thanks to the collaboration of trusted partners, we are in a position to manufacture pieces based on customer specifications, both in small and large quantities.
