Feeding of very light plastic parts in a vibratory bowl feeder is quite difficult. Such parts do not have much weight which makes them very difficult to orient. They do not stand up and even if they do, they have a tendency to fall off. Using air for orientation too is difficult as both the correct as well as wrongly oriented parts fall off. Hence, for tooling bowls for such light weight parts, special care has to be taken and they require to be tooled by very skilled bowl toolers. Of course, having experience in tooling such a part in the past definitely helps and hence it always better to get your bowl tooled from a reputed manufacturer who has had a wide variety of experience in tooling such light weight parts.
