Hi,
I was wondering if anyone know about these soft plastic coin holders/covers? & if so do you know who sells them or where I can get them from? This coin was taken from an ANDA show card with the 2011 kookaburra (I think). or maybe that's the 2009? Either way it come from a card.

is that a perth issue?

I have seen things like that on perth coins

[attachment=3218]That one is but they are made for these 50 cent coins aswell.

Yes I have seem the ram staff putting coins into them with the mobile presses.so the mint also has them

Coin capsules are just one of many coin storage methods

As I told you, these things are vacuum-formed from sheets, then die-cut. The material is probably PETG or PP, but don't quote me on that. Any thermoplastic would work, and polystyrene is common for opaque parts.

Here's an instructable on a DIY setup, as an alternative to $100+ commercial machines:

There are also a heap of youtube videos and other references, especially around the R/C aircraft modelling scene.

Given the ease of the process, and the large number of commercial users, I very much doubt you're going to find who's making these things for the mints, unless they tell you. Needle in a haystack and all that...

Back in 2009 the RAM capsules were made by a company in Brookvale NSW I peeked at the invoice on a box of them behind the counter when I was there for the master mintmark coin,goldseeker was there on the same day

I know but time is off the essence? what ever that means. If some one does make them for the right price it may be just better than the time spent making them. RAM told me to try Rennicks as I couldn't get it out of them. I will find them, and when I do.... your probably right and I was better off making them myself from the start!

as long as the time off work from the 3 degree burns doesn't out weight your cost savings .. well then you're on a winner!!

Not wrong, im dangerous at the best of times, my mate just bought a lathe and I know im definitely too careless for one of them. Im one of those blokes who would use an angle grinder and cut through the cord.

Thanks, you just made me remember the girl who literally ripped her face off when she got her hair caught in an auger. Her sister was driving the tractor IIRC and couldn't hear her screams over the engine noise.

Looking at the holder itself it appears as if it is meant to be heat sealed? Overall I recommend not attempting this outside an industrial environment as there are far too many things that can happen in a variable environment.

Trout's your Go-To guy for heat sealing Saflips.

Sorry I meant manufacturing them can be dangerous. Sealing them as intended by the producer would be fine.

Oh, I see.

Nah, not dangerous at all. These things are ultrasonic-welded.

Basically, you attach an ultrasonic horn with the shape of your weld to a transducer, then you stick your work pieces between the horn and an anvil and apply pressure. When you give it a pulse of roughly 20kHz sound energy, the contact point vibrates enough to melt the work pieces and fuse them together pretty much instantly, in the shape of the horn. The bigger the contact area, the greater the energy requirement.

You can make these welders yourself, using scrap parts. The only high-tech component is the horn, which has to be precisely tuned to the right frequency.

I've actually seen a small hand-held unit that could be used for crude 3D modelling. I think I was told it cost something like $300, but it was a while ago, so don't quote me on that.
