first, with the US company WABCO (Westinghouse Air Brake CO), for the production of three models of WABCO motor graders at its Monte Chingolo plant: these were 440, 444 and 660. This contract was in force until the mid-80's, where, since 1984, SADE (Sociedad Argentina de Electrificación) took over the production of 130 H and 160 H motor graders under the SIAM SADE brand until the decade Of 90 '. The second was with the International Harvester, for the production of the front loader IH Payloader H60B, which extended until the end of the 1970s. Decline and reactivation Siam Di Tella focused on its appliance and machinery units, though losses stemming from its defunct vehicle unit led to growing debts with the state small business lender, BANADE. Paying the lender with company stock in lieu of cash, Siam gradually made the Argentine government its partner. The latter absorbed Siam in 1972, after which the firm expanded into foreign markets through exports of its refrigerators, and into the transformer industry. The March 1976 coup and the free trade and deregulatory policies enacted by the last dictatorship's Economy Minister, José Alfredo Martínez de Hoz, affected the company adversely, however. Unable to compete with a flood of imported appliances in the late 1970s and beset by a national financial collapse in the early 1980s, Siam di Tella declared bankruptcy in 1981 and its facilities were sold by the National Government in 1986. The steel tube facility was sold to Techint, and their remaining appliance units to the Pérez Companc conglomerate and local appliance and electronics maker Aurora; another small appliance and parts facility in Monte Chingolo was acquired by Newsan in a joint venture with Sanyo in 1991. A renewed boom in imports ultimately led to the bankruptcy of Aurora in 1997. The remaining employees formed the Julián Moreno CIAM Cooperative, Ltd. in 1997. They resumed the manufacture of appliances at the Piñeyro facility in 2002 and employ around 200 production workers. Newsan, which had reinaugurated Aurora's Ushuaia facility in 2011, announced the reintroduction of the popular SIAM refrigerator line in 2012. The SIAM refrigerator plant was reopened on May 1, 2014, in a ceremony led by Newsan Chairman Rubén Chernajovsky and Argentine President Cristina Fernández de Kirchner; the new plant has a capacity of 100,000 units annually. Legacy Torcuato Salvador di Tella, the founder's eldest son, set aside 10% of the company's
