La Storia

Ours is an Italian story
of passion and results since 1949

  1. 1949

    Year of foundation.

    Delmet. Founded in 1949

    The company was founded on 13th January 1949 by Mr. Cherubino Cherubini under the name DELMET derived from Disossidazione ELettrolitica METalli.

    The original company mission statement read, “to employ in Italy and abroad, methods and procedures for metal deoxidization using galvanic process, so that metal could be reused following regeneration”.

  2. 1952

    First international agreement and use of patent for electrochemical polishing.

    From this initial activity, Delmet immediately expanded its scope of operation to cover electroplating treatments and electrochemical polishing in particular. In 1952 the first international agreement for electropolishing was concluded with an important German company, located in Munich. At the time, this company was specialising in the polishing of copper and its alloys and Delmet was awarded a licence for the Italian market.

    In 1955 a licence agreement for Italy was signed with CARL KURT WALTHER (known today as WALTHER TROWAL ) located in Haan, a leading company in the field of vibratory mechanical finishes. The exclusive arrangement, for supply of products and machines in Italy, remains operative today.

    In 1967, a demand of water treatment plants emerged and as a result, Delmet signed up an agreement with yet an other German company, this time located in Duesseldorf. From this fruitful co-operation, over 150 new plants were successfully commisioned.

  3. 1977

    Engineer Ruggero Rigatti takes over the management of the company.

    1975 saw the launch of a new process for chemical deburring of carbon steel and it seemed, for a while, that this might supersed its electrochemical counterpart. However, knowledge gained from experience showed both the different possibilities and limitations of the two techniques and that the electrochemical approach was often the correct one.

    In 1977 Mr. Cherubini handed over the management of the company to Mr. Ruggero Rigatti, who was to guide Delmet’s activity toward a higher degree of specialisation. Primary objectives centered on pickling, deburring, polishing and passivating of stainless steel and the relevant water treatment process.
    The rate of development necessitated Delmet to relocate more than once within Milan.

    At the beginning of the eighties, sub-contract metal finishing services were introduced to supplement the existing plant and chemical supply activities. The expansion and the increasing volume of work, required more space and facilities, so that in August 1985, Delmet moved its location to new industrial buildings in the Milan suburb of Gorgonzola.

  4. 1990

    Massimo Rigatti and Anna Cherubini take over control of the company adopting state-of-the-art automation techniques.

    On the death of Mr. Ruggero Rigatti in 1990, management of Delmet passed over to his wife, Mrs.Anna Cherubini (daughter of the founder, Mr.Cherubini) and her son, Mr. Massimo Rigatti. The expansion programme has continued and Delmet metal finished plant, both automatic and manual, can be found operating today not only in Italy, but also in

  5. 1996

    Opening of the Chinese market.

  6. 2002

    Realization of the first systems for stent treatment in Ireland and Italy.

  7. 2009

    Introduction of derouging on the Italian market.

  8. 2013

    Entry into the American market with the first plant in Cleveland.

  9. 2015

    Opening of the new Sub-contract facility service at Gessate. Construction of the first mobile “spray cabinet” unit. ISO 9001 and 14001 DNV GL certification awarded.

  10. 2017

    Launch of digital control systems employing “Industry 4” management.

Based on seventy years of corporate history and projected towards continuous innovation, massimo and anna have built a team that has led delmet to become a leader in the market of pickling, passivating and electropolishing processes. all this could be achieved thanks to a mixture of passion and state-of-the-art technology.

“Our strength is that we offer 360° solutions for all steel surface treatment requirements, aware that our technologies have to continue evolving in order to satisfy every need, optimizing the processes and respecting the environment. Innovation is in our DNA in the wake of the tradition of style and passion that have always set our company apart.”
