Where to scavange and cut high density foam

Where to scavange and cut high density foam

(OP)
Hi,

 I need to line a plastic case with high density foam to package some equipment. I know that i can buy HD foam from case vendors but, I was curious if there are some places where I could scavenge it or get it cheaper. Also, how do you cut HD foam to get the nice clean cuts?

Any advice is appreciated.

Thanks,  

RE: Where to scavange and cut high density foam

Hot wire knife might be one approach.  Not sure which particular foam you're looking for, but many such foams are used in the packaging industry.  

I've also seen the inverse approach; the equipment is wrapped with plastic and suspended in the cavity of the box and instant foam is applied around it.  Home Depot sells something like that in pressurized cans.

Rubber foams like neoprene or silicone should be available from any seal company.

HDPE is more common for packaging.

We have a big bin of the stuff downstairs in shppiing, I'm guessing they wouldn't notice if some went missingwinky smile.  Seriously though, any place around you that ships/receives relatively high value stuff like fancy electronics etc may have scrap.

As to cutting it, hot knife seems to be how they do it for most of the stuff we play with.  However, I've used a band saw with adequate results - though lots of 'fuzz' gets generated.
