Heat and mold techniques are fundamental in producing highly realistic sex dolls. Heating is used during the molding process to ensure materials like silicone or TPE flow smoothly into molds, capturing fine details such as facial features, skin textures, and body contours. Controlled heat application allows artisans to achieve precise, consistent results and helps in removing air bubbles that can compromise realism. Mold techniques involve creating detailed negative impressions of the desired features, which are then filled with the chosen material. Advanced molds are often multi-part, enabling intricate details like facial expressions and hand features to be accurately formed. These techniques also facilitate the production of seamless surfaces, eliminating visible joints and seams that can detract from realism. The combination of heat control and sophisticated molding results in durable, high-fidelity replicas that closely resemble human skin and anatomy. Continuous innovation in these methods ensures that sex dolls become more realistic, comfortable, and aesthetically pleasing, elevating their craftsmanship to new heights.
