RE: [OT]ish suction moulding machine?

Hello,



the food and chemicals business refer to this application as MAP - modified
atmosphere packaging (ie the packet you buy your sliced ham in).  They can
be expensive, such as here:

however I remember making a very capable device with a hot air gun, a piece
of ply with lots of holes, and a vacuum cleaner.  It was about 15 years ago
(about the same time I last posted to this group), so I'm afraid I cannot
give too much help, but I think it's more fun that way.



There may be easier ways to do what you want, though.  Depending on the
detail, it may be better to settle some placid material over the 'mould',
and then 'harden' it, but unless you remember papier mache (sp?) it may
hard
to get the materials.  If I find anything I'll come back to the group.



Cheers,

Paul

Hi all,

Odd request I know, but I'm putting the finishing touches to a touch panel
PC and need to smarten the front up a little. I'm thinking back to my old
CDT days in school where we had a machine a few feet square that was used
to

heat and then drop sheets of plastic onto moulds. Letting the plastic cool
down, you'd be left with some rigid plastic in the shape of your mould. I'm
trying to find a simple or cheap version on the web so I can design and
mould a front plate for my device.

If anyone knows a manufacturer or the technical name for such a product,
that'd be much appreciated.

Thanks in advance,

Jules
