Metal or plastic case

[terry]

Hi,

Could anyone give me information of roughly the price to make a case
for a device which is about 6cmx6cmx3cm and has 2 retangular holes and
one circular hole.

Which one is cheaper if the case is plastic or metal?

The quantity is about 500.

Thanks!

This assumes that you want to draw up the exact model yourself. If you
want a 3rd party company to lay out the details and then make it, your
looking at a lot more. But if its simple enough, i like these guys.

Buy off the shelf cases and have them modified. I doubt there will be much
price difference for the machining.

I am not going to make prototypes but production items. So I need the
price reference.

500 is quite a low volume for a production item. If you want a custom
designed case then the biggest cost factor for plastic will be tooling.
Could be $10,000-$15,000 dependant on the exact design details. With metal
you might stand some chance of making a case by folding which needs far less
tooling - more like $1000-$2000. If you want real quotes sketch a design
and send it to manufacturers.

Is EMC is an issue? Its easier to solve this with a metal case than to try
plating/coating plastic.

For 500 off I would still look at modifying an off the shelf case. Standard
catalog items can look very boring I know but there are some reasonably
smart designs out there that use aluminium extrusions to good effect.

I've tried emachineshop. It seems like it might be a nice idea but so

far it's not worked very well for me (I don't know about ordering I've
not managed to get that far).
