    Anyone have any suggestions for suitable companies to rota mold a 14 foot rowing boat, I'm east coast so eastern side of USA would be easier.

    There is a company in the Carolinas that specializes on that.

    I'd be interested in knowing more about the challenges of making an aluminum mold - and what they charge for the roto moulding.

    Gonzo, Do you happen to know the name or anything actually useful like that?

    Thanks for the replies guys. I was really looking for a recommendation based possibly on experience. I can go to the web and do a search but you can't beat a personal recommendation from someone that has had experience of a company.

    I made rotomoulded poo boxes and water tanks and deisel tanks, no big deal, but to make the mould for a dinghy certainly will be.

    I've wondered if it would be possible to hydroform thermoplastics - then you can have an open mold. It's also quick, so less heat damage to sensitive plastics such as ABS.

    not sure where you are there, the rotos are made from steel, they have a hole in them (or two or three etc) where you put in the pellets and off they go with burners on the outside keeping the mould hot. The pellets melt to the steel mould via centrifugal force...I would suspect that hydroform would need some sort of mechanism to get the little suckers to attach to the moulds.

    Yes, hydroforming is a different process that would typically start with a sheet or tube (vs pellets). Usually (always?) metal.
