Abstract
LA INVENCION SE REFIERE A UN PROCEDIMIENTO DE FABRICACION DE UN PRODUCTO PLASTICO EN UN MOLDE (20) QUE COMPRENDE UN SISTEMA CON CANAL DE BEBEDERO CALENTADO (22) Y AL MENOS UNA CAVIDAD DE MOLDE (21). UN FLUIDO A PRESION SE INYECTA A TRAVES DE AL MENOS UN CANAL DE FLUIDO (23) PARA CREAR UN ESPACIO HUECO (1) EN EL PRODUCTO FABRICADO. EL CANAL DE BEBEDERO CALENTADO 822) ESTA DOTADO POR AL MENOS UN MEDIO DE AJUSTE DE VOLUMEN (24) QUE PERMITE AUMENTAR Y REDUCIR SU VOLUMEN. UNA DETERMINADA CANTIDAD DE MATERIAL TERMOPLASTICO EN FUSION SE INYECTA MIENTRAS QUE EL VOLUMEN DEL CANAL DE BEBEDERO CALENTADO (22) SE REDUCE MEDIANTE EL MEDIO DE AJUSTE DE VOLUMEN (24). UN FLUIDO A PRESION SE INYECTA DESPUES DE QUE EL MATERIAL TERMOPLASTICO HAYA TENIDO EL TIEMPO DE SOLIDIFICARSE UN POCO. EL FLUIDO A PRESION REPELE LA MASA TERMOPLASTICA EN EL CANAL DE BEBEDERO CALENTADO (22), PUDIENDO EL VOLUMEN DE ESTE ULTIMO AUMENTAR MEDIANTE EL MEDIO DE AJUSTE DE VOLUMEN (24). LA MASA TERMOPLASTICA EN LA CAVIDAD DE MOLDE (21) PUEDE SEGUIR SOLIDIFICANDOSE , DESPUES DE LO CUAL SE EVACUA EL FLUIDO.
