Discussion about slush casting
editI wrote a paper on slush casting about a year ago, which appears to be about the same topic. Not being an engineer or metalworker (I'm an Industrial Design student) I didn't want to add the paper without a lot of editing, and frankly I haven't had the time.
Nice to see this up now, but can slush casting be mentioned in the article? Off the top of my head there are a couple of things which could be used to exapnd the article, but most entries about slush casting in textbooks were only ever a few paragraphs long.
1. The other type of toy made using this technique was toy cars. 2. The rate of cooling is dependant on the shape of the mould - ie metal cools faster on external corners and will therefore form thicker wall sections at those points (I had a good example picture, but it was from a textbook). 3. What types of metals were commonly used in this form of casting? Tin and lead alloys are about as much as I can remember. I think brass may also have been used. 4. Relation to ceramic slip casting. I see a very strong relationship between the two processes - does it deserve a mention?
A couple of edits I would make to the main page
edit'Molds come in two parts'. I would edit this to say that molds come in at least two parts, put perhaps more than two parts for complex casting shapes. 'Tooling costs are high'. Not if you make molds by casting the molds instead of milling the molds. — Preceding unsigned comment added by 50.47.108.136 (talk) 20:49, 22 February 2015 (UTC)
Discussion about Die casting vs Low Pressure Die Casting vs this
edit- I am not an expert, so forgive me if the differences are obvious, but i saw the term Low Pressure Die Casting being used, for something similar, if not identical to the Low Pressure process described on this page ( quick example of it's usage )
- Also i encountered the term "Coquille Casting" which seems to be a french(?) term for gravity, permanent mold casting (see This page ) (also This job site using the term )
Anyone here have experience in the area / know more about the terminology?
