Product specific criteria for selection of a vibratory bowl feeder

  1. Is the Vibratory Bowl Feeder FULL WAVE or HALF WAVE Operation?
    1. Due to FULL WAVE Operation, the vibrations are smooth and Spring Breakage is nil as compared to HALF WAVE Operation, which leads to regular Spring Breakage / Bolt Breakage
    2. FULL WAVE Vibratory Feeders CONSUME 60% LESS ENERGY as compared to HALF WAVE Vibratory Feeders.
  2. Is a Step Type Bowl being offered or a Cylindrical Bowl?
    1. CYLINDRICAL Bowls, which though cheaper, result in JAMMING of components and thus manual intervention every now and then.
    2. Step Bowl offer better performance.
  3. Is the Bowl either of Cast Al or Stainless Steel 304 Grade?
    1. Cheaper 302 / 303 or Mild Steel Bowls do not last long and perform miserably after a period of time.
  4. In case of Cast Al bowls,
    1. Is the tooling made in stainless steel or mild steel. Tooling should be made in stainless steel to be long lasting.
  5. Is Argon Welding done or only Tack Welding is done?
    1. TACK Welding reduces the performance of the Bowl Feeder after 6 to 8 months
  6. Does the Bowl have sufficient “Ribs” below the tracks?
    1. These improve the performance of the Bowl and also increase its life.
  7. Are the Coils totally Encapsulated or Open.
    1. Open Coils are not only lower in performance but also are very dangerous in operation.
  8. Are THREADED INSERTS used in all Aluminium Castings?
  9. Does the Vibratory Bowl Feeder have an overflow arrangement?
    1. This can eliminate the need having a Sensor thus saving on cost.
    2. It makes the Bowl Feeder more reliable.
  10. Does the Vibratory Bowl Feeder have a provide of “Window” to get the wrongly oriented components back into the Bowl or are those components taken into a separate tray for manually putting back into the Bowl?
    1. Providing a separate tray for manually putting back wrongly oriented components into the Bowl unnecessarily increases manpower and defeats the whole idea of a having a Vibratory Bowl Feeder.
  11. If there is a Gravity / Linear Track, is there a Sensor with Auto-Switch Off Facility?
    1. This switches off the Vibratory Bowl Feeder when the track is full, thus saving on power and importantly noise.
  12. Does the Vibratory Bowl Feeder manufacturer guarantee against Spring Breakage?
  13. Is any Lining / Coating being offered?
  14. Is the Lining / Coating Pasted or Sprayed or Rubber Molded?
    1. Pasted Coating comes out (gets removed very early
    2. Rubberised Coating does not last long and has a very bad finish (affecting smooth flow of components)
    3. Sprayable Polyurethane Coating of 0.8 to 1.00 mm thickness is the best as it gives longer life and better result. This type of coating also reduces the Noise Level drastically.
  15. What type of Finish is provided?
    1. Buffed finish looks cheap and results in slipping of components on the tracks
    2. Bead Blast Finish is the best and equivalent to European finish.
  16. What is the Vibratory Controller being offered? Is it of an Indian or European Make? Is it having CE Marking? Does it have facility of Voltage Compensation and OVERLOAD CUT-OFF.
    1. Due to Overload Cut-Off & Voltage Compensation, Coil burning problem is totally eliminated resulting in major savings on Spares.
    2. Indian Makes have a lot of problems and are not stable over a period of time.
  17. Is the Controller housed in either Polycarbonate / Sheet Metal Control Panel?
  18. How many Fuses does the Vibrator Controller have?
    1. It is better to provide 2 to 3 fuses as a safety measure
  19. Does the Vibrator Controller Circuit have MOVs of sufficient rating? This is an added safety measure.
