The manufacturing process of full-function sex dolls involves a combination of advanced materials science, precise engineering, and skilled craftsmanship. The core structure is typically made from a rigid internal skeleton, often constructed from metal or high-strength plastics, which provides stability and poseability. Over this framework, a soft, flexible material—such as medical-grade silicone or thermoplastic elastomer (TPE)—is applied to create realistic skin textures and features. These materials are chosen for their durability, flexibility, and lifelike feel. The face, hands, and other detailed parts are meticulously sculpted and painted to achieve natural appearance and expressions. Internal mechanisms, including motors, sensors, and heating elements, are embedded to enable movement, responsiveness, and temperature control. Wiring and electronic components are carefully integrated to ensure safety and functionality. Quality control involves detailed inspections, testing of mechanical parts, and calibration of electronic systems to guarantee smooth operation. Customization options, like eye color, hair, and body features, are incorporated based on user preferences. The entire process requires a combination of manual artistry and technological precision, ensuring each doll is both aesthetically appealing and functionally capable.
