Googling for Paper Molding brought up a ton of articles on the subject. I'm curious how does paper molding differ from molding using paper pulp discussed under category of papiermache?
One paper molding article spoke of using a "vacuum" to squeeze the paper pulp and remove the moisture at the same time. Does anyone use a vacuum dome over a papermachie piece to dry the PM?

I guess this is really referring to an industrial process, like moulding egg boxes etc. Do you have any evidence of it being used for our type of work?

There is such technics of vacuum in the papermaking. These is dry with a vacum table in papermaking. But the objects in PM are 3D mostly. So such
vacuum will very difficultly and dearly.

There is a world of information about "paper" mache and paper-pulp which come back depending on how one phrases the search and which search engine is used.
There seems to be some grey areas between casting paper {i.e.molding} and papiermache. Here are some URL's that may be of interest.

"Cast paper is much like papier-mache. The dry materials are made into a thick pulp, then pressed into molds."
I see terms like casting powder, and linters being used.
http://www.baph.org.uk/ has a very usefull glossary of terms.
Some others that zeem to reveal a cross between casting/molding and papermache:

Paper pulp work is kind of the missing link between making paper and papier mache...in paper making it's considered at the far artistic end because it's an end in itself (i.e., it's not paper that can be written on or 'used').
Since a fair amount of handmade paper sheets are formed from pulp made by soaking and blending small pieces of existing paper, the line between paper and papier mache is so thin that it's hard to see.
But using a vacuum doesn't have to be expensive, at least in the U.S. where you can buy a fairly powerful shop vacuum for between $50 and $75. I use my setup for paper sheets but I filched the idea from the paper pulp people. The main components are the vacuum on the bottom, a framed screen in the middle, on which the wet pulp or couched sheet goes, and a cover made from plastic sheeting (I use either a disposable drop cloth or the thicker stuff that's a cheap substitute for storm windows).
Then duct tape fastens the plastic sheet to the vacuum hose.
There's also a non-electric method that's supposed to work, which involves a wooden box, with screening on the top. The bottom is hinged and supposedly when it's opened the paper from the top rushes down. Some books on making paper show the technique.

The next to last sentence should have read "the water rushes down"...obviously there'd be no point if the paper did the rushing.

I don't waste time arguing about what papier mache is.
If *I* say it's papier mache, IT'S PAPIER MACHE! So there! 
Newspaper for PM is vegetable fibers rolled thin.
Cotton linter material is vegetable fibers fluffed up.
Pulp can be made from either one, and mashed into a mold.
Pulp can be made from either one, and smeared over newspaper strip PM.
If you want to paint it, it's still PM.
If you want to cement beads, glass, tile, seeds, or cat food to it, it's still PM.
If it doesn't have any paper fibers in it at all, it's probably NOT papier mache.
See how simple things are when you focus? :twisted:

That's sort of what I was getting at but you said it much better. In several decades I've never heard a papermaker say anything bad about papier mache--just the opposite. The paper pulp people (I love that phrase), on the other hand, draw snickers occasionally for pretentiousness.
