There are several main methods for heating the dolls.
1. Wire heating
2. Heating sheet heating
3. Heating blanket.
The first and second methods are to wrap the heating wire or heating sheet along the skeleton.To prevent breakage, the heating wire can only be wrapped till to the upper arms and thighs.This forms the heating area shown in the figure below.
Of course, there is another technology. Subcutaneous heating technology. This technology allows the heating area to be extended to the entire leg and the entire arm.But due to the high price, only XTDOLL currently offers this option, and only silicone dolls.
In addition, because silicone has poor thermal conductivity, you cannot feel the heat obviously. Therefore, for silicone bodies, we do not recommend internal heating. A heating blanket is a good alternative.
