Re: [Z_Scale] Re: Micro Trains wish list
Making the mold has to be kept in mind during every stage of the design
process, from prototype selection to the placement of details and textures.
Depending on the amount of detail, undercuts, etc. the actual manufacture of the
mold can take weeks or even months. I can't speak for MT's process
specifically, but mold making generally requires several different machining processes,
some automated, some not so much. The link below explains some of the basic
principles of mold design. This is a site that does rapid injection molds for
relatively basic parts. It is not the exact same process that MT or Bowser or
AZL(?) are using. But it is a pretty good source for general information on
the process. There is also a cool pdf document that explains the strengths
and weaknesses of various rapid prototyping techniques.

Pardon for asking, but I'm not familiar with the process
for making tooling for plastic injection molding. What are
the main costs associated with doing so? How does one
go from from a prototype to new tooling? (I'm leaving
out the cost of research, measurements of prototype cars,
etc. I'm talking just about actually making the mold.)

>Dom,Hi Mike, unfortunately I can't give you a reply with the match MTL Flex / MTL turnouts as I'm using Pater Wright's turnouts ( http://www.wrightturnouts.com ). Finally I chose them instead of MTL's samples because I found that even the MTL's are prone to stalls at very low speed, although they are power routing. Wright's turnouts are to this prospect completely "clean" due to their technology, with non-articulated points.

And About Marklin's turnouts and tracks I can't say, I don't use them as in my opinion they don't match prototype american track (and this ugly side mechanism bores me).
