Shouldn't this article be merged to casting? ··gracefool |☺ 00:56, 3 February 2006 (UTC)

No. Although the noun mould (mold) is used in both the areas (moulding and casting) and the terms moulding and casting may be synonymous, their application within industry is different. When used in relation to the plastics industry, moulding is the preferred term (injection moulding, blow moulding). Amongst the casting industry it's ...casting.

I notice that the french wiki links casting to Moulage which looks like it incorporates injection moulding and casting under the one term - underlining the (understandable) confusion with the terminology. Advances in technology have blurred the boundaries as areas borrow techniques from each other, ie: squeeze casting is a process very similar to injection moulding.

From a purely personal perspective ie: FWIW. If I pour liquid clay into my cupped hand - that's casting. If I then push and shove that clay into shape, that's moulding. And Yep, if that analogy was on slashdot it would end up an offtopic thread with a thousand corrections, but in the absence of anything better... — Graibeard ^(talk) 01:02, 5 February 2006 (UTC)

What does, "There are no known parallels for this mould." mean in the caption under the image? I'm drawing a blank as to what the author is implying. (160.84.253.241 21:13, 11 May 2007 (UTC))

My guess would be that "There are no known parallels for this mold." is referring to a second half of the mold. 10:35, 4 August 2007 (UTC)

Spelling

As an Englishman, I spell the word "mould". A mold to me is the fungal growth when my cheese starts growing whiskers. Is the spelling used here an American one, or is the word missplet in this and various related articles? Peterkingiron 14:24, 4 June 2007 (UTC)

In my UK English dictionary "mould" is how both the fungal growth and the subject of this article is spelled. Mold is the american version of this word in both cases85.210.133.86 10:48, 4 August 2007 (UTC)

Mold design and manufacture should be addressed

I noticed this article does not yet address the design and manufacture of molds themselves (except in the case when that is part of the mold creation). It seems there's both a mold-making process and a mold-using process (molding). I imagine abstracting this process to something more like:

1. design for object (materials, shape)

2. design of mold(s)

3. repeat 1, 2 as nec.

4. create mold

5. test mold

6. go back to 2 as nec.

7. utilize mold

This assumes that the mold would be for relatively large production. Perhaps, though, what I describe above is closer to something like a "molded object production".

The reason I bring up this topic is that I noticed that "parting line" was not in Wikipedia, yet determining one is an integral part of designing a mold for an object. The term Molding flash exists here, though.

What is the basis of the assertion that molding ( moulding ) is the opposite of casting ?

Seems like they are the same, to me .Eregli bob (talk) 07:02, 7 March 2008 (UTC)

Molding and casting (verbs) are the same, but mold and cast (nouns) are the "container" and its "content", so they are indeed different... --Janke | Talk 07:31, 7 March 2008 (UTC)
