[sdiy] Plastic case fabrication

[Happy Harry]

Depends on the method used. Injection Molding is very
expensive, maybe $10K for the mold (from experience) I think
Rotomolding might work if the shape is very simple.. The SKB cases
are made like that. Blow molding is used to make milk jugs, if that would 
work.

If you can find a suitable container that someone ELSE is making, contact 
them. If its a mod to a standard product, you can save a lot of money.

Try the Thomas Register (if possible) or regional guides to get some
contacts, or search for some of the molding techniques that I mentioned 
above.
