Abstract
Procedure to obtain by blowing and in a single piece hollow bodies of great volume, that being of special, although not of exclusive application, with polycarbonates, is characterized essentially by comprising the following operative phases, taken in combination: A) obtaining, by injection molding, a preform, substantially tubular, whose general configuration is that of a cylinder opened at one end and closed on the other through a spherical cap of radius equivalent to half the diameter of the cylinder. B) blowing of the obtained preform, until taking it to adopt, within the corresponding mold, the finished form that is pursued. (Machine-translation by Google Translate, not legally binding)
