Italian innovation, worldwide excellence

CGS VACUUM offers machines and services for metallization using PVD technology: Vacuum metallizers for aluminium coating and vertical metallizers equipped with twin door-chambers.


Our services and application

Our company provides technical support services of metallization systems, with planned maintenance services, interventions in h24 * for plant shutdown in the national territory. Worldwide service in all country and representative in the major country.

Wide range of spare parts for the systems, equipment repair services, research leaks with helium and many other advisory services and modernization of facilities. Our strength is also to study together with the customer solutions aimed always to satisfy the customer.

Our Application for metallization Systems

Replacement operator interface in obsolescence of existing machines. To date we cover all configurations of existing Galileo machines on the World market with two types of systems oversight:
  • System Single machine, able to manage the system and also generate a report data for local consultation.
  • Scada data collector system, designed for companies with multiple machines, networked, the interface communicates with a SCADA application that collects production data to archive data and generate reports operating statistic and calculate OEE remotely. Replacing control evaporation with new generation capacity control in the phase controller with adjustable monitoring V2 or VxI. The control is replaced in the existing obsolete, with a rapid change in the existing PLC program.
DC engines being replaced with new three-phase asynchronous motors controlled by inverters allowing interchangeability with trading engines by replacing the custom control board with inverter V / F.

Revamping work on machinery

Since 2012, the year in which CGS Automazione srl was established, it has always carried out revamping work on machinery that is no longer recently built. The sectors in which it operates are many, but specifically it specializes in the modernization of vacuum systems for objects and roll to roll.

The company has extensive know-how in these sectors given the decades of experience of its engineering staff on these plants. This staff is partly from the Galileo Vacuum System.
The revamping is carried out by viewing the machinery through an inspection at the customer or through the customer’s photographic collection that allows us to have as much information as possible about the machine, in order to be able to reconstruct its history.
Then begins a feasibility study phase and its modalities, to arrive at the issue of a quotation for the implementation of the modernization work.
The offer traditionally includes electrical work on the new electrical panel, the new wiring on the machine, the reconstruction of the pneumatic system, where also mechanical maintenance of the system is required, with overhaul of the pumping organs, valves, search for leaks with our instrumentation.
At the time of approval of the offer, all the materials are prepared, the panel and pneumatic parts are assembled, everything is tested at our company and then sent to destination by the customer after testing.
At the customer, two of our technicians in charge begin to dismantle the old panel and electrical system on the machine and then start the new installation, positioning the panel, passing the new control cables etc. operations that normally take 2 working weeks.
Once the electrical assembly has been completed, the panel turns on and the testing of the pumping components begins, performing vacuum cycles without production. After that you start moving the planetaries, heat the sources, try the ion discharge power supply. Finally, the machine starts to be tested automatically by calibrating the various phases of the cycle for their correct functioning to obtain the desired production.
Testing operations typically last 1 working week.

The example listed above is for Batch type machines for the metallization of objects, for roll to roll machines the methodology is the same, only the execution times of the activities vary.

The software used is open-source, our technicians are able to perform changes requested by the customer to customize the machine, furthermore all the panels are equipped with remote assistance via VPN router, guaranteeing the end customer constant assistance in the case of problems.

The deep roots of the CGS VACUUM can be traced in the extraordinary scientific and historical panorama that pervaded the Florentine Area. Impossible not to think of Galileo, as well as Torricelli.

Later, in the second half of 19th century, two astronomers had the assignement to build up an astronomical observatory in Florence. They founded, as support laboratory, the first “workshop Galileo” that was developed subsequently as a company operating in optical and vacuum technologies. This company became in the Florentine Area the seeding of many others innovative activities. CGS VACUUM fits into this tradition and offers its machines and services for metallization using PVD technology.

Our history

Our company started as supplements to the industry of automatic machines in general. Since 1975, year of establishment of the CGS, we have always worked on the design and programming of automatic machines for OEM. Over the years we have gained experience and new knowledge in many fields of industry. Every year we have always set goals aimed at business and professional growth, looking to consolidate our customer base.

In 1995, we acquired new business partners in introducing us marked the pharmaceutical machines, we have consolidated over the years leading our company to grow in size with a view to medium- and long-term investments.

In 2012 with the arrival of new staff from the company Galileo Vacuum Systems, you were presented new growth prospects for our society, in the world of machines for the vacuum coating. Thanks to our know-how, we started to collaborate with leading lights production groups in the automotive sector.

In 2015 came the first orders for the renovation of the Italian customers to plant systems.

In 2016 we have consolidated the Italian market and we have had some positive feedback from the rest of the world markets. 2016 also marks the year of birth of our production lines for our storage facilities under vacuum.

Our mission for 2017

Strengthen our presence on the world market: we already have contracts with the US and India, and we have ongoing discussions with Japan, Thailand, China, Austria, Germany, Egypt, Taiwan. And obviously sale of our first production machine!

The next 5 years

  • New production site.
  • Reach 10 plants / year.
  • Cover all markets, with agencies in strategic countries.
  • Investment in new technologies.
  • Growth and formation of new technical.
