I have read a bit about using plasticine to create multi piece moulds. How would you break up the mould? I had a look tonight whilst cooking the Barbie- nothing jumped out at me as the obvious place to do it. Perhaps into thirds across ways using the edge of the centre opening? Otherwise into thirds vertically with the splitter, vertical surface with all the ducts, and then the curved headlight section?




It is a bit of a suck it and see kind of thing. It really depends on the shape. If you have curved surfaces that wrap around multiple axes, it is simply not possible to have a one piece mould, when you try to pull it off it is wrapped around the part. Don't look at it in a "how can i divide this mould up conveniently" kind of way - think about making it as easy as possible to get the part out.

Q: mold or mould? I have used both in this thread and both look wrong.




Mould it is. We speak and write the Queen's English here. Damn seppos and their inability to spell. Next thing you know, you will be telling me the color of something is gray
