Designing soft-touch silicone sex dolls involves a complex blend of artistry, engineering, and technology. Manufacturers start with detailed anatomical studies to ensure proportions and features are as realistic as possible. Advanced 3D modeling software is employed to sculpt lifelike facial features, body contours, and textures. Once the design is finalized, high-grade soft-touch silicone is used for casting, allowing for precise replication of intricate details like skin pores, wrinkles, and subtle expressions. The silicone is carefully formulated to achieve the desired softness and elasticity, ensuring the doll feels authentic to the touch. During assembly, internal support structures and joints are integrated to facilitate natural movement and positioning. Facial features are often crafted with replaceable inserts or movable parts to enhance realism. The surface is meticulously finished to create a smooth, velvety texture that mimics human skin, often with customizable options for skin tone, eye color, and hair. Customization options extend to body shape, height, and other aesthetic features. Overall, designing soft-touch silicone sex dolls is a sophisticated process that combines artistic detail with technical precision to produce a highly realistic and personalized product.
