First Linmar's problem:
I think that if the purpose is to hide fingerprints and microscratches, then sandblasting with the proper grain size should do.
Back to satin:
thanks Kenvlach for the definition “A diffusely reflecting surface finish on metals, lustrous but not mirrorlike." Are there...
I disagree with the two previous replies. Satin finish is characterized by surface appearance, that reflects light in a dull-yet-shiny way. This can only be obtained when the direction of the surface texture is parallel to one main direction.
In my industry (luxury accessories) this is usually...
We currently laser weld small Stainless Steel pins into through-holes. We are finding it impossible to do it with gold (we manufacture luxury-goods accessories). Does anybody have experience with laser-welding gold?
Our laser is a 700W Trumpf unit; welding speed 1000 mm/minute; laser beam...
Can anybody point me to additional sources of texture? At our company we have the UG module "Visualize", which already gives a fair smooth reflecting surface. We need though to arrive to an even better Mirror-Polished reflection, which is not available in "Visualize".

HellBent, thanks for the suggestion. I'm told though that think3 is the leader in PLM. Have you had any direct experience in comparing UG's PLM vs other companies' PLMs?

Hi,
very interesting what you say. But if
"param re-creation is VERY hard ... when you have to operate on a model made by someone else"
this goes counter the goals of team work, process independent from the operator etc. Then I have to make sure to standardize the rules for parametric...
Thanks Cbrn,
I agree that migration from one CAD application to another would be a nightmare. I wanted to understand which software had better parametric design. And that you clarified it for me, thank you.
I'm interested by your further comment that: "parametric modeling makes one save much...
I've stumbled into think3 software (www.think3.com), and that company shows demos of parametric design, where the designer can easily modify the 3D. We use UG, and my chief designer tells me that UG can do the same. He also says that in our type of design (metallic watchbands, with up to 300...
Unclesyd,
I would be very interested in reading the malleability chapter of the handbook you mention. Could you give me the title, author and editor please? (Ciriani@Promotion-Spa.Com) I would also like to find out which austenitic SS is more malleable (I believe it is 316, but you never know)...
I agree that malleability is a colloquial term, and that there isn't a measurable number associated with it. Actually I should have said ductility: from a linguistic point of view I'm always confused between malleability and ductility.
Quoting the web page of my previous message, at page 25...
Happy 4th of July!
Mike and Ed, thanks for the explanations, and the Allegheny website. I guess I completely overlooked the fact that ferromagnetism is also a no-no (watch components and accessories like the watchbands we produce) have to be non-ferromagnetic. Therefore duplex SS cannot be used...
Hi Mike! How do the new duplex grades compare relative to 316L in the following categories (all relevant to my industry, SS luxury goods):
(1) Machining ease (speed of utensil advancement);
(2) Malleability (it correlates well with mirror polishing ability);
(3) Nickel content;
(4) Nickel...
Thanks both Berti and BTrueBlood for your tips. After all input, I'm leaning toward VMQ (especially because of the easier colorabilty).
However, the vendor assures me that there are scubadiving goggles made of NBR, and that any compuond can be tweaked to improve resistance in certain...
Thanks Btrueblood! Would you say that skin grease is enough to break down EPDM over the long run? And would the break down turn eventually into cracks?
Thanks Berti! VMQ seems a good choice; is it also weather resistant? Do you think that FVMQ is good too?
An injection molding supplier said that NBR, start breaking down, even after 1 hour in salt water, and suggested EPDM. What would be the pros and cons of VMQ compared to EPDM?
I need a tip from a real elastomer experts!
I'm looking for an improved NBR (Acrylo-Nitrile Butadiene) for watchbands, that lasts longer than what is usually found in the market. I'm actually not sure if NBR is the best rubber around for this job, or if there are FKM-, EPDM-based compounds that...
Loctite has charts for what glue to use for what type of plastic. For polyolefins I've used their type 406 with a primer 770, and the bonding was very good. They are coming out now with a one-component glue called 3300.
I'm looking for an NBR-like o-ring to be used in a consumer-goods application. I'm confused by all the data sheets found in various sites, and I need some tip from elastomer experts.
Current need is for basic black color, but I will also need other colors, like red green, yellow, blue in future...
