These are indeed the complaint of many.
And, you are correct that the hands and toes can be fixed by injection molded parts of high temperature plastic. However, they have many problems for a sellers point of view. Its another thing to break. You've now added 100 more joints to the doll, which means 100 more points of failure. Still, it would be better than the wire fingers for breaking.
And the breasts really require a completely different solution.

A part you might not know is that TPE is heated up to molten and poured into the mold.
So, it will melt previously cast TPE, especially the softer formulas.... and although it will probably work, the results will not be as planned, and may be better or worse and/or inconsistent.
Further, the biggest problem in casting sex dolls is getting the insides to stay where they are supposed to be inside of a mold. The placing of the skeleton into the mold is a pain in the ass, requiring a lot of accurate man-nipulation.
Now, a two stage pour might be beneficial, as you can do fixes to the internal (guts) layer and maybe have a piece that is more "one-piece-ish" to put into the final mold. But, i feel that you will get as many problems as you get solutions with this.
It may be a real boon to pour the internals in two parts, in an open face mold. So, you can see and position (fix) the skeleton while pouring.
Now, your ideas may work lots better with Silicone.
In silicone dolls, the silicone is really just a skin. So the internals are foam and metal. Unfortunately TPE eats silicone and silicone does not always work with other silicones.
Such as, platinum cure silicone (actually uses very fine platinum to cure it) will never cure right in mold that has ever used tin cure silicone. And silicone jells react poorly to silicone solids.
So, finding things that work well together is a pain, but doable.
The other problem you want to fix is breasts.
Breast physics are a pain to model. You have something that acts like firm water, inside an thin elastic containment vessel. And, we currently have no "firm water" or thin elastic material that is strong enough.
Now, people have done slime filling of TPE hollow breasts, with, to them, great results in giggle improvement.
But, really, the things that need to be worked out is strengthening the TPE to ripping, while encapsulating something that will stay like "firm water" for the life of the doll.
I am working on solutions, but it really isn't a problem of something i haven't thought of, it is a try various things until you get a better result.
This is where some shooters get their ballistic gel from https://humimic.com/product-category/medical-gels/ you are going to want number 4. I have not tried this myself so therefore, I do not know if it will shape shift. You know, if used on a doll for breast and you lay the doll down on her back will it spread out, or if she is on her knees will it dangle like, two soft fleshy milk-secreting glandular organs on the chest of a woman aka titties etc. Right now as of 05/30/2019 they have a sale on these gels that represent different body parts, from brains to breast and muscles.
The problem is the breast outer housing. To be durable it has to be a bit inflexible. Flesh is different. There's little else like it.
I'd love it when the doll is laying on her back that the breast sag the right way. But that's really really hard to do. The silicone (and I only deal in silicone) would have to be completely different than the rest of the doll. It's possible to mix silicone types on the same doll but it's really hard to get right.
There are many elements at play including ligament structure muscle density and Joint placement. These are all problems with every manufacturer I've come across. The solution is complicated definitely doable. I've already got very thorough plans laid out for such an endeavor. Just need to build up some funding to actually get a production run going. Hopefully the doll community like the designs I've been working on, then I get roll over those sales to fund a small design factory. That is unless someone out there wants to fund this artist
Something I have not seen anyone mention is shape. The shape of the breast is hugely important as well. If you make the breasts too perky then there will not be enough skin on the underside for the breasts to move much. The breasts on most of the dolls I see online (likely older models) do not have a shape that will allow for much bounce. The same is true for smaller breasted models. the Breasts need to have some sag and the skin of the underside of the breast needs to go under the breast; the more bounce you want the deeper under the breast the connection to the chest needs to go.
You can see what I mean with this gif.
If you look at her left breast, the one further away, when gravity pulls her and her breasts down it looks as normal but when you see her jump the shape changes to more of a triangle shape. That is the shape you would need to make the dolls in if you want to get a realistic bounce. If the doll is made like that then when the doll is standing, gravity will pull the breast down and it will look like normal but then also be able to to change shape when force is applied up. If you make the dolls with the tear shape then they do not have enough skin on the underside to allow for the bounce even if you use soft materials to allow deformation.
Here is a video of what I keep seeing with dolls today. https://www.pornhub.com/view_video.php? ... 3f74&t=260
Here the shape of the breast remains the same and just moves up down and side to side because the shape is stuck. What we think of as a normal shape is actually deformed by gravity and not the biological shape. Sadly we do not have footage of naked women in zero gravity. This video does show the transition between gravity pulling down on the breasts and then some other force pushing them up so you can see the deformation and how they should change shape. https://files.sexyandfunny.com/mp4/usr_ ... 694b4e.mp4
Slime seems to work pretty well but I think there is a more fluid solution: Glycerine as a filler. From what I've read, water based lube is made with it so it should be safe to use a mix of glycerine and water to fill up hollow tpe breasts. It should also be easy to inject the glycerine with needles instead of having to make an incision on the doll. What do you think?

How would you inject the cavity without creating a slow leak?

Modified turkey syringe. The needle would need a one way valve at the base with a quick connector to the syringe.
Then you just draw glycerine> connect and inject> detach> draw glycerine> rinse and repeat your way to jiggle paradise. Seal it with a soldering iron right after.
Also keep track on a sheet of paper the volume you injected so you can do both sides evenly. Do it from the armpit area near the breast like they do for implants on humans.
This is all rather interesting, just something I've been thinking about too as of late (nothing to detailed as posted/added on here). But while I do love the feel, size and general grab of my girls D's, I do kinda dislike how when laying down the boobs defy gravity (as it would be for woman). I'd sure say it would be an improvement.
The gel thing also read...One thing I'm unaware of, maybe someone here knows for sure, but the hollow breast are actually like bags (as in a wall of material other than TPE, well filled with air obv.) in/under the tits right? And the idea is to empty the air, and replace it with slime/fluid, right?

Air would not allow the breasts to move like real breasts, that is why they need a liquid filling. There needs to be something with weight in order to make gravity pull the breasts in different directions. Water has weight but is too viscous. Gel or a liquid silicone is less viscous but still allows for the breasts to be affected by gravity in the right way like real breasts. The problem then comes from the thickness of the skin of the breasts. If the skin is too thick then the breasts will not move properly but if the skin is too thin, it will move properly but it will be fragile. It is a difficult problem to solve.
Yes I understand that whole thing, just curious if there are like bags in there (sealed of from the tpe) or if putting in some 'border-material' is also part of the operation (if one would put something other than air).
The Kimber doll is constructed with an internal chest cavity of foam plastic and covered with a Silicone Rubber layer.
The quality of this outer material is damn good aesthetically, except when it comes to the breasts as you have discussed at length in your post. Would not want to get smacked around the ears with them
donoghu has some interesting thoughts on breast physics. Personally I don't have any experience with silicone/TPE compounds other than my observations that the feet of the Kimber mini have a nice fleshy wobble to them. A breast moulding with a similar wall thickness as that of these particular feet would leave a small cavity in the breast. As for the potential problem of the breast ballooning when a fatty such as I plonks onto the doll, having the cavity extend into the chest area (foam in the Kimber) allows ballooning internally.
Or looking further down the track of dolls being manufactured with density variation seems the way this industry is heading.
I still get weirded out by picking my doll up and there is no freaking backbone.
Along with breasts, rubbery heads, nonhuman skeletons and orifices that move with the orientation of the upper legs, there is much more to be discussed and done in this field.
even if they had a injection of a gel like semi liquid to make breast flow more life like in movement the problem then would even be the breast material skin would have to be thin enough to allow the breast to not be to stiff but yet thick enough to last and also durable to last otherwise what would happen is a tear in the breast etc. as we see happening on some dolls now. but in a gel injected breast the semi liquid would also leak out .
bottom like it's all about making a better durable doll skin , something i and many others have mentioned in the past.
