'[OT]: Plastic cases'
2000\11\21@085639 by jb

I'm looking at having some plastic cases manufactured for a commercial
project. Anyone care to share their experiences with the process of
designing/manufacturing cases for your projects? Do you make them in-house,
or out source? Setup costs? Gotchas? Are there case companies with vast
pre-made selections that might save me setup/design costs?

My requirements are fairly reasonable (at least I think so): 4"x2"x2"
internal space required, holds a small circuit board, line transformer, a
switch or two. Should be a bright color and maybe have a raised/sunken
logo/brand (a decal would do in a pinch).

Thanks.

injection moulding is pretty expensive for small runs - the tool for the job will be a few K
dollars. per unit costs are obviously pretty cheap after that.

check out these people for custom manufactured plastic boxes. have not dealt with them myself.
apparently there are a few companies who do similar stuff:

these people make some nice standard boxes:

For off the shelf, check out Pac-Tec and Bopla.

At IFCO, we did our own case designs.  We used Solid Works for design and
things went quite well.  Tooling for a small complicated case (such as the
R21 receiver) can run $40k to $60k to get the kinks out of it.  After that
it is clear sailing except for QC issues (witness lines, color, etc.)

Currently at Capita we are using Pro Engineer which is a much more capable
package at a much more uncapable price.

The cheapest way to go is to have them custom molded for you if your
quantity is high enough.  For injection molding you will probably have to
produce over 50K per year to be cost effective in a steel tool.

For lesser quantities there are cheaper tools and methods.  Aluminum and
epoxy tools can be used for 10K to 50K runs.  Vacuum and thermal forming can
be used for low quantities (5k or less) if you design is not critical
mechanically.

SLA modeling can be used to get onesy twosies (don't ask me how to spell).
If the model is cleaned up enough, it can be used to make a mold for low
quantities.


A word of advice.... choose a molder and tool house close to you.  Use the
tool house that the molder wants to deal with.  We are all a little screwy
(no offense to you non-screwy ones) and these guys will know how to deal
with each other.  Little things like how the gating is done, how the mold
pulls apart, and how temperature variances occur in the tool itself mean
alot.

If volumes are sufficient you can probably get a standard case made in
a special colour without costing too much extra.

We went the other way - took our design and made it fit an off the shelf
PolyCase box. It seemed for the quantities that we were dealing with (<1K),
it wasn't worth the effort. A polyester metalized label fit perfectly on
the case and we are very happy!

You could try Serpac ( http://www.serpac.com ), Hammond Manufacturing (
http://www.hammondmanufacturing.com )
or LANSING ( http://www.lansing-enclosures.com ). I would try to get an off the
shelf enclosure unless
you will be selling them in large quantity.

Best regards,
Steve

You asked for plastic, but...  I believe that custom sheet metal is
significantly cheaper than custome plastic up through rather large
numbers of units (or very odd shapes.)

Also many screen-printing places can print logos and text
on a plastic or metal case quite easily if it is fairly
flat. Many places will happily do tiny quantities (10)
with no problems but expect you to pay for screen making
and then x per unit. The result looks very professional
and even some big manufacturers use a similar system.

Beg pardon but what is SLA ?

SLA: Stereo Lithography - It's that 3D process of using UV resin and lasers to create a 3D model from a drawing. I think there are actually several methods and materials, but that's one of them. See:

       http://www.stereolithography.com/slainfo.html

BTW, thanks to everyone for the numerous replies to my original question on this. That is some kind of an expensive process I guess, probably out of the realm of possibilities for me at this time. Looks like stock cases, modified to suit for this project.

stereo lithography. See these links.

http://www.bath.ac.uk/~en7rge/rmassn.htm
www.agocg.ac.uk/train/hitch/layerman/report.htm
http://www.designinsite.dk/htmsider/p0051.htm

The first link gives a very good description of the methods. I do have a caveat
about it though. I have not used it myself, and the only example of it I have
seen seemed to be  quite brittle. It is a great way to get a prototype shape to
test everything fits, and you have done the drawing right, you may even be able
to deliver a prototype or two so your end customer can do the same, but unless
there are better plastics available than I have seen I would be wary of using it
for even limited production.

the SLAs themselves are also very expensive, so you really don't want to be making more than one. a
common approach is to make a silicon mould from the SLA and then cast a number of copies from that
with a low temperature resin. depending on how critical exact dimensions are, you only get around 20
copies off that mould before it starts deteriorating too much to be of any real use. these casts are
not cheap either of course, and colours are pretty limited - pretty much 'beige or nothing' :)
if the design is not too complicated or dimensionally critical then for small quantities you would
be hard pressed to beat the cost of fabricated parts. fabricated metal parts would probably be
cheaper than fabricated plastic, as there are an awful lot of metal bashers competing for trade.

Regards,
Simon

>SLA explanations

Thank you all for that, SLA is new to me.

What about that other technology to make cardboard (?) models using a 3
axis router and a turntable ? (this I saw in a TV presentation). I don't
remember the names involved.

Try Hammond manufacturing.  They have standard line and will do custom.
