A vacuum former has well known results, even though most people don't know it's name. A vacuum former is used for the plastic covering on product packaging.

A vacuum's quality is indicated by how little material is within it. The quality is usually measured in gas pressure (as torrs). A torr is a historical unit, although still used for vacuum quality. The Si unit is the Pascal.
Oh, dude, Otto von Guericke invented the vacuum pump in the 17th century. It's like this device that sucks out air from a space, creating a vacuum. So, yeah, he basically made it possible for us to understand the concept of a vacuum. Cool, right?
A vacuum pump is any device which does work to transfer air from one volume to another volume, and thereby reducing the pressure of the first volume. There are several different types of vacuum pumps available, each operating over different pressure ranges.
If you are talking about a condenser attached to a steam turbine, then a vacuum is important because it extends the usefulness of the steam in the turbine. As you probably know, steam begins to condense back into water at 212 deg at atmospheric pressure. However, in a vacuum condition, the boiling and condensing temperature is lower. Because the condenser is under a vacuum, steam exits the turbine and enters the condenser around 130 deg. This results in more power (mega watts).
a vacuum former is a machine that is used to heat up plastic and mould it to the right shape.

A vacuum former is a plastics melter which has a springy bed and on it. Place the shape desired on the platform and the plastic sheet on the side opposite from the vacuum inlet. The plastic will be heated and pressed over the shape.Specific safety instructions should be followed depending on the model used.

what kind of timber would be best suited to make a mould for use ina a vacuum former
A vacuum former shapes a piece of plastic by drawing the heated, softened material down over a cast or mold. With a partial vacuum (lower air pressure) below, the outside air presses the plastic down to closely match the molding shape.
the plastic is HIPs (high impact polystrene) but the thing that you lamanate can be anything as long as it's reasonably flat!
A vacuum bed can be used for BDSM play. A vacuum bed is a latex envelope spanned by a frame, and a suction pump or floor vacuum removes most of the air out of the envelope.
It used 5200 vacuum tubes.
