Dear Masuo & List Members:
I recommend Rotational molding for prototyping large hollow
Patterns can be made via LOM or CNC from which cast aluminum
molds can be made at a substantially reduced cost.
I can estimate a pattern, cast tool, part price so that you can
perform a price comparison. Please e-mail IGES surfaces to

> Dear Mr.Dickens and my colleagues,
> In Japan, there's the need for the large parts prototypes such as dash

> Since they cannot believe the reliability of CAE, they prefer to have
> parts made by real plastics.
> Sometime they use the vacuum casting which is just used for their

> always look for the cheaper way of prototyping.
> Is there anyone who can suggest the solution for this kind of needs ?
> They're not satisfied with urethane vacuum casting but as far as I
> there's no good injection tool like epoxy tool to inject the large
> parts like dash board.
> Any suggestion is highly appreciated.
