Pressing ahead Presezzi Extrusion

PRESSING AHEAD

With a family history in industrial machine technology Presezzi Extrusion is now one of the most important extrusion press suppliers on the global market and its name has become synonymous with high-level technology and flexibility in the development of different kinds of extrusion presses, writes Beverley Young.

Located in the north of Italy just outside Milan, the company finds itself in one of the most advanced industrial areas in Europe for metal processing. I spoke to CEO, Valerio Presezzi about how his company was formed and the reasons for its success.

“I grew up in the world of mechanical engineering”, Mr Presezzi begins, “gaining experience in our family company, Bruno Presezzi, which produces mechanical components for energy systems. In 1994, I decided to form Presezzi Extrusion focusing on the production of extrusions in aluminium, copper and brass using the latest technology and innovations. We now have two main production centres, the first here just outside Milan and the second at Brescia in the Verona area; sales, at the moment, come to around €40 million a year.” Presezzi Extrusion is geared towards expansion and at the moment is working on a joint venture with a multinational company which will take its production beyond the Italian border. “This will enable us,” states Mr Presezzi, “to gain an even greater impact on the developing countries of the Far East and South America.”

A research ‘philosophy’

Presezzi presses, with their cutting-edge technology, built using the most advanced software and 3D projection, have proved to be particularly successful in the automobile, railway, shipping and aerospace industries.

“Our highly skilled research and development department uses FEM calculations which are normally only used in universities and research institutions,” states Mr Presezzi. Significant investment in research has resulted in the production of extrusion presses which have obtained the highest level of built-in automation and energy saving, thanks to an innovation patented by Presezzi known as Presezzi Extrusion Energy Saving System (PEESS) which guarantees a 20–30 per cent saving of energy depending on the type of production. The first machine to be developed with this system was sold in Germany in 2009.

With its Italian market already well established Presezzi now exports 90 per cent of its production to countries such as Germany, Poland, USA, Canada, Russia and China and every piece of machinery is equipped with a unique after sales back-up system which is also a result of the company’s dedication to research. It is the ‘black box’ data system. “Every machine,” explains Mr Presezzi, “is fitted with a black box which enables us to constantly monitor its function from our Italian offices 24/7. In this way we are immediately aware if any irregularities occur and can intervene at once. For this reason we rarely need to go out to customers to intervene locally, saving all round on costs. Should a more hands-on approach be needed, however, we can instantly call on our branch offices in China and the USA.”

“We have also just recently opened a new division which concentrates exclusively on energy,” states Mr Presezzi. “This division is

already staffed with a group of qualified engineers who are working with the universities of Milan and Pisa. At the moment, we are working on an experimental project involving the production of energy through mud purifying.”

Cost-effective trouble shooting

Presezzi Extrusion does not only create highperformance and reliable presses but can also supply any specific complementary tools and accessories to use with this machinery such as Isotherma, Data Manager and centre press shearing. These accessories are not only designed to fit Presezzi Extrusion presses but also those made by other manufacturers, and the company is proud of its speed in delivery, from the designing to the supplying of any spare part. This is part of Presezzi Extrusion’s revamping programme whereby the company can improve the performance of any older press by creating custom efficient and affordable solutions, essential in today’s economic climate. These revamping processes can be either partial, in which certain parts such as the main cylinder or extrusion tie rod are replaced, or ‘complete’ in which the entire mechanical, electrical and oil hydraulic parts are replaced. Among the company’s goals is further expansion with the opening of a network of new offices around the world in order to provide even greater support to overseas customers and also to observe more closely the new trends and needs of foreign markets.

“We are constantly driven by the desire to produce more efficient and cost-effective machinery,” claims Mr Presezzi, “and to ensure that all our customers receive immediate service. For this reason we are ISO 9001 certified. It is this attention to the quality of our products and customer service which is at the heart of Presezzi Extrusion’s success.” n

BRUNO PRESEZZI

BRUNO PRESEZZI is an Italian engineering and manufacturing company of machinery for production of aluminium strip (twin roll continuous casting lines). Five machines are installed in Italy, one in Turkey, and two complete lines with related melting and holding furnaces are now at commissioning in the Emirates.

BRUNO PRESEZZI has also been for over 30 years a worldwide, reliable supplier of cores and shells for twin roll casters, with top performance for durability and strip productivity. Hydro Aluminium has selected BRUNO PRESEZZI as a key supplier for these products, and has recently assessed it at top level for quality and reliability.

New design and materials solutions for rolls are being introduced to improve product quality and productivity, as well as cost effectiveness. The BRUNO PRESEZZI Patented design of caster rolls with grooved shells is well established today and is going to be further improved to fully exploit its capability for enhanced performance. New steel grades are under development with the same goal of improving the cooling efficiency.

Hydro Aluminium is testing and well recognizing the potential of the innovative solutions of BRUNO PRESEZZI for the improvement of its continuous casting process and of the quality of its flat rolled products.
