Snap-fit drawn steel enclosure?

[deadeye]

I know this is not the right forum for this but I didn't know where else to go. Delete if inappropriate.

We do a lot of work with small (2"x2") deep-drawn steel enclosures. We're looking for a supplier who provides some kind of snap fit sealing method for same. I can find tons of deep-draw sources but see nobody offering a snap fit function. Probably because there's no-such-thing. Anybody have a place I can look? Or a more appropriate place to post?

If I must ask, it probaboy means I can't help but one never knows.

What is a snap fit sealing method/function? Can you describe it?

Sorry, after rereading my question, it does sound vague. Check out the drawn enclosures in the photo at this site:

We use similar square enclosures and we currently 'slipfit' a shallow drawn cover over the open end of them and then solder-seal. On some non-hermetic units, we would like to install a cover over them and have it be secure without having to solder. We have some 'custom' ideas for solving this but had hoped that there was something standard out there.

Thanks for the reply.

I have seen custom formed metal parts with mating "ridge and groove" to lock them together. It is another set of forming operations and they sure don't seal, they just provide location and retention.

A formed lip is always involved. Might be easier to form a 3rd piece with Z section
