Rotate the mold to form the outer layer of the skin of the sex dolls

My biggest problem is the sex doll mold itself, and I haven’t collected information there yet (obviously, fiberglass / resin will be considered). As the manufacturer says, for the skin, this is a well-preserved mixture. In fact, if they sell dolls, most of them sell their toys. 4woods said it took 10 years, another took over his father’s business for 20 years, and so on. Impossible to mix successfully. Not to mention technical limitations, for example, the super soft doll ecoflex (which will be completely powdered) requires rotating the mold to form the outer layer of the skin of the sex dolls, and then casting silicone into it. I understand the difficulties very well and even have an annual budget. If I just want a sex doll, I will buy it, and it will cost less.
