>>6122424>>6122424>>6122424Here's a Metal Build's elbow joint. There is a layer of heavy plastic (ABS or POM I assume) sandwiched between the diecast parts. The similar construction is used on the hips and (I guess) the double-jointed knees. The shoulders are entirely plastic. Do they work? I change poses infrequently, but I guess they do a good enough job of keeping figures stable for weeks and months on end. I'm not planning on doing a stress test anytime soon though, someone else do that to their overpriced collectible.
Also, from the measley few SoCs I own, I noticed that they also use a kind of diecast ratchet. This is obviously a great deal better than the disastrous metal ball joints used on stuff like some early Super Robot Chogokin figs (those were trash, I'm still bitter over the money I spent on those only for the damn things to die the diecast death-flop).
So, I suppose the lesson is that diecast on the joints really only work if they're engineered well. Which ultimately means using plastic on all the spots that matter anyway. Top kek.
