That's a good one.... Sounds like a mechanically resistant material with a crystalline structure (the reason I chose it) - also the corresponding low thermal-expansion coefficient, this is why together with molybdenum it is used with quartz... It shatters rather than bend.

I found a chapter of some guide about working Tungsten carbide (attached). See page 33 "low temperature soldering" do you think that might work on a ring... ?

Thanks all :)
The only gear I have in my lab is a simple soldering tool, silver melting temp is around 960 C, which is way too high for it...
I noticed that the electronic-shell configuration of silver is very different to that of tin - so I wonder if the 2 metals, the tin and the tungsten...
Hi all,
I bought a Tungsten-carbide ring which has turned out to be too large... I thought of making the inner diameter of the ring smaller by soldering some tin in a thin layer onto the inside of the Tungsten-carbide ring.
I know Tungsten carbide would not melt anywhere near the melting temp...
Hi Ninja182,
Thanks for your response. I am looking for someone who can build a casing to (my) CAD and yes - polishing and anodizing reflectors - getting harder and harder to find in the EU - I need that too.
This job in not for a once-off, but longer term, since we design new product on a...
Dear all,
I'm looking for a tool-shop in the EU that can make lamp-houses and reflectors, both prototyping and small-series.
Thanks :)

Oh and another thing..... When I registered here I selected (Electrical) for my field - because my real field (Applied Physics) was not available.
Now even when I go back to my "Personal profile" I'm unable to change this selection, it appears nowhere.
How do I change it ? An off-topic...
Hi greg, my other option is to have the system sent back to me, since the original adapter from Japan is not even sold in the EU, I still have to buy something local (standard product which I can buy at the HW store), I test briefly and ship back to the customer, I charge them some x3 the...

Custom-made parts are a different story - then the customer pays for engineering not only standard parts.
ya I guess I might be a bit of an idealist there - an approach I'm quite certain will not be reciprocated by most...
MikeHalloran :
Right about the documentation, generally engineers hate writing reports, but it is a necessity. My previous company won a claim from a supplier who screwed up due to documentation and emails I kept, this taught me never to delete anything.

Thank you all. Let me take it from the top :

Honesty and clarity are indeed the best policy IMO - I intend to pursue that.

1. I want them to repair simple parts by themselves - replacing a power-adapter with a standard connector should not be a problem for an...
Hi all,
The company I work for recently started selling complete systems rather than just loose components. As a product manager it is now my job to set up service policies and plan a future service department.
Naturally I find the challenge very exciting - because my first job was in field...
