Trowal continuous vibrators are especially designed for the continuous processing in one cycle by feeding the work pieces in loading cycles.
AV machines have a trough shaped (rectangular) work bowl. They are most suited for
- processing of robust mass produced parts of small and medium size (stampings, die castings)
- deburring and grinding of mid- and large-size components (engine and pump housings, oil pans, cylinder head covers, etc.).
Trowalizing in continuous operation with continuous loading of the work pieces offers considerable advantages compared to the batch operation:
- Easy integration of the mass finishing process into continuous
manufacturing processes (flow or cycle production)
- Little time exposure for automation of mass finishing processes
- Little time exposure for material-handling, since in most cases no batching of work pieces is required.
