Since I don't make wax RP parts at the moment, I've never had the problem of
shipping them, but I have a suggestion for how you might accomplish it.
If you pack the part in fine sand (or clay, talc, or plaster) and vibrate it
to compact it around the part, it will produce a fine nest to hold the part.
The problem is with the material shifting and the part being put under
If you pack the sand around the part in a bag, and vacuum seal it, you will
end up with a stable brick of sand that is relatively immune to damage.
They sell coffee that way and I am amazed at how strong the brick of coffee
is before it's opened. (It works the same way as the v-casting process.)
Of course this will add to the shipping cost due to the increase in weight,
but hey, if you can guarantee shipment of undamaged parts...
Just an idea.

Subject: Idea for research project to solve shipping nightmare
Kenny / Phill et al
Further to the previous thread on Shipping of parts, etc. and having just
received an undamaged, apparently well-packaged box of 2 urgent parts (one
of which was in 6 pieces, the other in 7 pieces...) I have a suggestion for
a future research project....
How about sorting out a definitive packaging solution for waxes / delicate
layer built parts which more often than not end up broken or damaged
(usually only on critical projects!)
Having witnessed over 10 years of trial and error (as both supplier /
customer) using various combinations of: boxes within boxes, eps peanuts,
bubble wrap, sealed air pockets, inflatable bags, cotton wool, shredded
paper, silicone rubber, ceramic etc. there is still no comprehensive
solution for this as far as I am aware.
Geometry and material are the key variables, and I am sure that list members
could provide some suitable test geometries. (Wax turbine wheels for
automotive diesel turbos for starters).
Potential end result could be a packaging solution for delicate parts
available at a premium. If this could effectively guarantee the safe
arrival of your parts, then it would be worth the extra ($10? $50? $100?)
Am I crazy or would this be best solved by a research project approach?
I am tortured by visions of boxes suspended by springs on all sides that
couriers could play soccer with and still not break the part(s) held safely
Any comments / ideas welcome.
