Talk:Spin casting

message: :I agree, what the page says right now is all over the place and pretty misleading and I've only ever heard spin casting refer to either a fishing technique or the silicone mold cast procedure for metal or thermoset plastic parts.  Chocolate is news to me.  I'm going to try to draft a whole new article on this topic, but I'm not really sure how to link it with related articles and series such as the metal casting series.  If anyone is interested in offering some help there, i'd appreciate it.
:I'm working for TEKCAST Industries, Inc. a Spin casting equipment manufacturer in the US, so I should be able to provide something accurate and informative.

thread_title:  This needs a whole new article 

message: It seems two different methods of casting is being talked about as one here.  Spin casting does fill the mold cavity completely by centrifugal force.  However, slush casting (cermaic slip, chocolate, etc) the mold is only partically filled and is rotated on all axis (slushed) so the entire wall cavity is coated thus producing a hollow object.

thread_title:  Slush Casting 

message: Okay, so I just posted a new, much more expanded and informative article then that which covered this subject previously.  As I had said before, i work for TEKCAST Industries, a manufacturer of commercial spin-casting equipment.  I don't intend to use this article a veiled advertisement for our business, but as I add photos and additional details(external links and citations) I feel its difficult to provide a useful context without referring to the equipment manufacturer or source of information.
My impression is that Wikipedia doesn't necessarily encourage vendors to write articles about their markets, but the previous article lacked a lot of important information.  If anyone has any suggestions on how to go about contributing appropriately in this situation, please let me know or just comment as I continue to add more about spin casting.
Thanks

There is no group called spincasting. Please make sure you typed the web address correctly. If you have done so, the group may no longer exist.
Can anyone confirm if the group has closed or if it has changed it's name?

replies: text: Thanks for bringing this up, the group actually changed it's name, It's now "Freshwater Models Spincasting".  I'll add the new link now.  Pushlatency (talk) 22:22, 16 April 2008 (UTC)
thread_title:  Broken Link 

message: I noticed there is also an article called Centrifugal casting -what's the difference, if any? Shouldn't that just be a redirect to here? --Satrughna02 (talk) 22:59, 14 November 2008 (UTC)
replies: text: I've added the merge template. I'm not very familiar with the processes, but from the gist of the descriptions they seem to be the same or similar. Wizard191 (talk) 19:00, 29 January 2009 (UTC)

text: It sounds to me that they are two different processes that just share spinning as their common link, so I'm going to have to say they shouldn't be merged. Thanks for the explanation. Wizard191 (talk) 14:54, 21 February 2009 (UTC)
thread_title:  Proposed merge with [[Centrifugal casting]]

message: Pioneered by Roger Angel at the Steward Observatory's mirror lab, this makes large () thin parabolic mirrors by spinning the oven as the glass is melted and cooled.  I've generally heard it called "spin casting".

replies: text: Sounds like a separate article as Spin casting (mirrors). We already have three articles, so there should be a Spin casting (disambiguation) page too. Or would Centrifugal casting (disambiguation) be preferred? Andy Dingley (talk) 19:14, 8 March 2011 (UTC)
replies: text: The former, but now we have the latter. I've taken the liberty to start Spin casting (mirrors) based on the above suggestions, and to link it to rotating furnace. - Rod57 (talk) 00:15, 17 September 2012 (UTC)
thread_title:  What about the parabolic mirror making technique? 

message: Are the molds split into top and bottom or are the parts removed by stretching the mold ? What is the typical number of parts made in each mold in one casting operation ? - Rod57 (talk) 00:23, 17 September 2012 (UTC)
