摘要

"Equipment of blow moulding with pre heating and method for raising the speed of production of articles molded by blowing in a process of reheating blow".The pre heating equipment for pre heating a selected portion of each one of a series of preforms to attain a thermal gradient persistent before reheating and blow molding the preforM.The pre heating equipment is mounted in adjustable in a gravitational ramp that carries series of preforms downward under the influence of gravity through the equipment pre thaCement in the direction of a molding machine reheating and blow.The pre heating equipment includes a housing coupled to the ramp so that the portion selected from each of the series of preforms is protected from the environment and elements hereEcedores fixed in the interior of the housing.So that the heat from the heating elements to be directed to the portion selected from each of the series of preforms as the preforms descend by gravity gradient.
