General Pattern in Minnesota specializes in large parts like dashboards
and door panels. They have a lot of specialized equipment to handle the
large parts molded from SLA patterns. The company has been around for
decades molding large parts and they have recently switched (early
nineties) to SLA patterns as the masters. I believe they now have 10 or
so SLA's. They have a web site but I don't know what it is.

I've visited their site and it is very impressive. They do a lot of work
for the USA auto industry and have also done work for the Asia Automotive

Dear Mr.Dickens and my colleagues,

In Japan, there's the need for the large parts prototypes such as dash
and bumper.
Since they cannot believe the reliability of CAE, they prefer to have the
parts made by real plastics.
Sometime they use the vacuum casting which is just used for their initial
concept models but, they usually build the prototype injection tool to
inject the real plastics although it cost them 60-70% of the real tool,
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 know
there's no good injection tool like epoxy tool to inject the large size
parts like dash board.
Any suggestion is highly appreciated.
