Vibratory Feeders, Inc (VFI) products

Cascade bowls are primarily used for feeding easily oriented parts like screws and dowels. They are often quieter and less costly than outside-track designs. Since there are no "over and under" tracks for parts to wedge between, improperly oriented parts are rejected back into the bowl falling only to the lower track. These bowls can be coated with a variety of materials or welded and polished to meet FDA specifications. They also lend themselves to lining with sheet urethane for wear and noise abatement and with 3M Brushlon for feeding oily parts. All bowls are fabricated from 11-gauge 304 stainless steel and are heli-arc welded. Tooled bowls are polished on the inside and painted on the outside.

Outside-track bowls are used when more intricate tooling is required for proper part orientation, for higher feed rates, or for multiple lines of feed. The outside track is usually pitched downward allowing parts to separate and be more easily oriented. By tooling on the outside instead of the inside, parts tend to buckle and fall into the return pan instead of binding.
