Improvements introduced in the object of the main patent no. 336.143, by: "improvements in the manufacture of parts of mortar or cement concrete getting with automatic machines", characterized by the disadvantages referring to the permeability of the parts obtained in said machines, because the water-cement ratio has to adjust to a certain field of values, by the vibration and pressing effect to which the mass is subjected, they are saved by obtaining a film rich in waterproofed cement, on the entire inner surface of the molded part, by the rotation of an internal molding means, two to two, independently, or together, and with a determined value of speed of rotation, issues that are determined, varying the characteristics of the operation according to certain guidelines by experience, and because in said internal molding means the core of holes or the diameter of the holes has been reduced. They themselves to achieve better results in the distribution of the liquid irrigates the inner surface of the molded parts in its manufacturing process.
