Ioan,

 Thanks, I did look at their site, they do have a footed valve with an encoder on the motor. Someday I would like to revisit the paste dispensing area and I might try one of those. I also saw a valve at APEX with a pressure sensor right at the tip and the turn monitor. I want one of those! Auger turning is an important control but you cannot ignore tip pressure. At high pressure the solder separates from the flux and you end up with a wad of metal in the tip.  It is a difficult process to control. The "Experts" at some of the vendors do not always get it right.

Thanks,
Bob K.

Bob,

I would also consider http://www.pva.net

They started by building valves, so they have a lot of experience. Have never used them for solder dispensing, but got very good service for epoxy dispensing and conformal coating.

De : TechNet [mailto:[log in to unmask]] De la part de Bob Wettermann Envoyé : Wednesday, March 23, 2016 9:55 AM À : [log in to unmask] Objet : [TN] Auger Driven Dispensers

Gents/Ladies:

We are looking at putting a non-pneumatic drive dispenser on a robot. Due to some pretty fine dots, the need for speed and for consistency and the need for some lines to be dispensed, we are looking at an auger-driven system (5-6 mil dots).

Does anyone have favorite vendors of the dispensing pumps and controllers that can be added on to a pieces of automation equipment?

Regards
