Plastic injection molding is VERY expensive (prices quoted are correct) each
cavity side will be multipled up in a tool set to produce 2,4 or 8 sets. So
each ship is going to have to be pantographed up that many times into Tool
Steel (long process if its an artistic shape) The plastic set for the game
'risk' cost $45,000 to produce (in hong kong with cheap labour!!) cf this with
metal from a master many silicone moulds can be cast, fill these with hot lead
and when cool remove and re-use (no 100+tonne press required!)
The lead path is so simple many people can have a go and end up a co.

I'll admit, I'm curious... but then, I'm a Materials Engineering major
co-oping at a specialty steel plant. ^_^ (Where, in spite of what that
one fellow said, we *do* make corrosion-resistant steels for plastic
molding!)
Thanks,
