The present invention refers to a manufacturing process of a ballasted tub for use in connection with oscillating assemblies of laundry treating machines, such as clothes washing machines, combined washing and drying machines and clothes drying machines, of the front-loading kind. The present invention further refers to a tub manufactured with such process. The manufacturing process according to the present invention is characterized in that it comprises the following steps of:
a) forming a first and a second body (2, 3), each one of them comprising a substantially cylindrical drum-like side portion (4, 9), in which a first end region (5, 10) thereof is at least partly closed by a wall (6, 11) that extends transversally relative to the extension plane of said drum-like side portion (4, 9), and a second end region (8, 17) thereof is on the contrary open;
b) forming a disc-shaped member (14, 14', 14");
c) associating said disc-shaped member (14, 14', 14") to said first end region (5) of the first tub body (2) so that, between said disc-shaped member (14, 14', 14") and said wall (6), there is created at least one cavity (15, 15');
d) providing balancing means (25) and arranging them so that, upon conclusion of the preceding step c), said balancing means (25) are at least partly housed within said at least one cavity (15, 15'). Claimed is also a tub (1) made in accordance with said manufacturing process.
