<p>Making of module ball refers to technology of production of PVC ball filled with compressed air, accommodated for installation of different modules, depending on the size of the ball ( light emitting, sound emitting ball, light emitting buoy and similar), as well as to procedures and technologies of installation of modules into the ball wall, so as to shape the bed in the interior of the ball, in which corresponding module is simply pressed in, while the ball retains all essential properties of the ball, without any disturbance of its shape, balance. This is achieved by installation-of the balancing mass opposite to the module, ensuring good sealing due to clamping joint between the module and the bed.</p> |
