Injection process to reduce the static unbalance of a plastic injected fan
for motor cooling system of a motor vehicle
The aim of the disclosed invention is to reduce the static unbalance of an
injected plastic fan for motor cooling system of a motor vehicle. The
chosen process is the addition of injected flyweight coming from the same
injection step than the fan injection step and the use of a mobile pad in
the injection mold to modulate the weight of the injected flyweight. The
first realization mode presented Fig 1 is to add injected flyweight (1) on
the fan distal ring (2). The second realization mode presented Fig 2 is to
add injected flyweight (1) on the fan blades (3). In this case the
flyweight could have the shape of an air deflector improving the airflow
capacity of the fan. The third realization mode presented Fig 3 is to add
flyweight (1) on the fan hub (4). Alternatively to fig 3, the flyweight
(1) could be localized in the internal face of the hub (4). In such a
case, the flyweight does not disturb the airflow.
