These are samples of CB wheels (Guessing) Arm and arm with weapon in opposed quadrants for balance (or maybe 3-4 parts?). Aquiles bodies. A basic humanoid seems to be at least 2 moulds, and could be 3-4 (generic antennas, head, heavy backpack...). Edit: typo.
There isn't really a 'wrong' way to organize one's molds. There's definitely 'wrong' ways to lay out your individual molds, but assuming the individual molds spin properly, there isn't a 'wrong' way to organize them in terms of production. Here it look like CB is doing multiple molds for a SKU. Nothing wrong with that. It looks like the 'body' mold has 15-16 cavities whereas the 'bits' mold has 5-6 cavities for each piece. Assuming you get 100% fill rates (which you won't, but let's assume for the sake of simplicity), it means CB has to spin a bits mold three times for every body mold. You could do this by having three copies of the same bits mold for every body mold, for example. One reason to do this is that the 'bits' are smaller and could fill more consistently with different RPMs, or maybe with a slightly different alloy. So you run them on a different machine, or at a different time than the 'body' molds. The tradeoff is that you have extra labor in collating the various components, which are difficult to identify by purely visual inspection. And that's any miniatures. The parts are small and shiny. Details are hard to see. Obviously, CB does fine with its production process. You can easily make a balanced mold that has both the 'body' pieces and the 'bits' pieces that gives you a reliable fill rate. The reasons to do one versus the other comes down to minutia of personal preference, observed efficiency, pipeline, and so forth. Maybe your staff seems to get about 10% fewer miscasts on average with separate 'body' and 'bits' molds. Maybe you like to use a different alloy for the 'bits'. Maybe your miscast rate on 'body' parts is comparatively higher than 'bits'. In any case, it would be incredibly easy for CB to manufacture alternate parts if this is how the company sets up its molds. In fact, with the digitally sculpted miniatures, CB could theoretically design alternate arm options to fit on the extant models and simply insert new molds into the production process. Alternatively, CB could put all of the various alternate options into the 'bits' molds. The point is that it's eminently doable in a way that does not, in my guestimation, significantly alter the COGS.
