BIG-SIZE-O-RINGSSiliconiton owns a very large compression moulding machine, with which it is possible to manufacture parts up to 1500mm of internal diameter. These articles are mainly purchased by Customers, which supply the shipbuilding industry, especially for what concerns the engines. In fact, the biggest diesel motor ever built, the Wartsila-Sulzer RTA96-C, was produced for ship applications: it is characterized by a cubic capacity per cylinder even of 1.820.000cc and can be composed by 6 up to 14 of them. These O-Rings usually come from one or more parts of drawn compound, which are cured under compression.
