Sure its not metal but it's not politics or global warming!

I was wondering why rotomolded plastic water tanks are so expensive.

The raw materials are generally regarded as cheap, the manufacturing
process seems on the surface to be simple. I guess transport /
distribution of a bulky product could be costly. Anyone got some ideas?


How big? They are formed in ovens MUCH larger than the tank, and the mold
cycle times are very long when compared to injection molding.
