Hi, I noticed that you removed <!--Note: Merge this info to the Casting (metalworking) article, and then redirect this article name to the disambiguation page --> {{Mergeto|Casting (metalworking)}} I'm no expert on the subject, but the way I'm seeing it, the types of casting can be divided in 3 types; these are: those

• Using an expandable mold (sand; divided in green sand & sand + resin) --> material (sand of mold) is recovered
• Using an expandable mold (ie lost foam process, lost wax process, concrete mold) --> material (mold) is lost
• Using an non-expandable mold (metal mold, plaster mold?) --> entire mold is recovered

The methode that uses a metal mold can be divided in, I read in Dutch "coquillegieten, lagedrukgieten, hogedrukgieten, centrifugaalgieten"; I assume that these are the forms mentioned at Casting_(metalworking)#Non-expendable_mold_casting

Hence, to me it seems like the articles have a very confusing set-up and have overlapping sections; it is therefore that I stated to merge the info from this "Casting" article to Casting (metalworking). Likewise, other article sections at "Sand casting" are also incomplete and confusing, particularly Sand_casting#Types_of_molds, and especially "no-bake molds" in this section,

• also the making of the seperate "Resin casting" article is confusing, this article would need to be part of "Sand casting",
• the "flask molding and flaskless-molding is confusing --> flaskless molding is best made part of the subsection of the Sandcasting article regarding "green sand"; this as the "Sandmold" is made by increasing the amount of bentonite (a substance (clay) of green sand);

There are different ways to categorized metal casting techniques, however I don't think any reputable sources do it based on the three types you outlined above. You would definitely need to supply a ref for that categorization. I'm not sure how you don't see that concrete casting and resin casting are completely different animals from metal casting. That is why the metal casting portion was split from

The

hatnote or something that's fine, but the material that's covered in the resin casting article has zero to do with sand casting. Siawase (talk) 23:40, 11 December 2010 (UTC)[reply

I didn't understand it that way, so that article is about Casting with resin ? However, from what I read in my book, I then think that Sand casting with resin also exists. That method indeed makes a mould from sand by combining the sand with resin. If indeed both types exist, should we distinct ? And/or can we integrate the second in the sand casting article ?

• Your many detailed and complex questions deserve an equally detailed reply.

However your evident ignorance of everything to do with casting (casting with resin has so very little to do with resin-bound sand casting) means that we can simplify this: No.

To a beginner, there is no way to distinguish or understand the precise difference between molding and casting. There is no hard fast rule? — Preceding unsigned comment added by Santropedro (talk • contribs) 19:01, 20 January 2019 (UTC)[reply]
