Alternative parts cleaning

I have a client that manufacturers small carbon steel parts for the automobile
industry.  They stamp and form the parts from rod-drawn wire on large presses
using Renocut 464, a petroleum cutting oil, at the rate of 35 parts/minute
coming off the presses.  The oil helps lubricate the cutting as well as the die
movement.  We are looking to eliminate one of the cleaning steps, which has
become a bottleneck, as all parts produced in the factory are cleaned at one
wash station, causing parts to sit and not flow at the rate we have targeted.

The cleaning step we would like to eliminate occurs after the parts come off the
press and before they are shipped out for off-site services.  They have explored
other lubricants with little success.

The outside vendors have required the cleaning because they do not want to be
responsible for oil draining off the parts during transportation, causing a
spill that they will be responsible for cleaning up.  The parts are shipped in
metal containers, holding 18,000-21,000 parts (2000 lbs.) and have to have a
trap door to enable the vendor the easily remove the parts from the containers.


1.  Is there another way that would remove the oil without having a separate
wash operation?  For examples, could we use a centrifuge at the press or are
there in-line washers that you have had experience with that would work with
this quantity of parts?

2.  Are there other cutting oils available that could provide the lubrication
necessary for this operation, facilitating the cutting and the die movement,
yet enable us to eliminate the wash?
