WM Doll

WM Doll (金三玩美 / Jinsan) was founded in 2010 by Liu Jiangxia and Wang Qingfeng in Zhongshan City, Guangdong Province, China—now the world’s largest silicone doll manufacturing base. The company initially produced clothing mannequins before transitioning to adult dolls in 2012, and by 2016 had become one of China’s first manufacturers to integrate AI capabilities into sex dolls. Today, WM Doll operates from a 3000㎡ facility with over 200 full-time workers, produces approximately 2,000 dolls per month, and holds more than 100 patents. According to industry estimates, four out of every ten silicone dolls exported from China are manufactured by WM Doll, with 90% of sales coming from overseas markets including the US, Germany, Japan, South Korea, and Australia.

Material Innovation: S-TPE & The Evolution of TPE Technology

While WM Doll has earned its reputation as a TPE specialist, the brand has continuously refined its material science. In 2023, WM Doll introduced its proprietary S-TPE (Super Thermoplastic Elastomer) formula, which according to user reports offers significantly better tear resistance compared to other manufacturers’ S-TPE versions while maintaining exceptional softness. This advanced material retains the lifelike, skin-like texture that made WM Doll famous—with the brand claiming their TPE “is as close to human skin in feel you can get”—while improving durability and reducing oil seepage. WM Doll also offers full silicone options, primarily through their SS series silicone heads, which feature ROS (Real Oral Structure) upgrades by default.

AI Integration: The MetaBox Series & Emotional Companionship

WM Doll has distinguished itself as an early pioneer in AI-powered sex dolls. Their flagship MetaBox series integrates large language models including ChatGPT, Llama, and DeepSeek to create interactive companions capable of long-term memory, personalized feedback, and meaningful conversation. Users can select from eight distinct personalities, with the doll remembering previous conversations and responding accordingly—for example, recalling the user’s name and engaging in context-aware dialogue. The second-generation MetaBox, scheduled for release in wearable form (necklaces, bracelets, and rings), will make AI compatibility available for all existing WM Doll models, even those without built-in LLM capabilities. This technological leap is expected to drive a 30% increase in sales, with the brand positioning itself at the intersection of physical realism and emotional connection.

Skeleton Engineering: EVO, MLS, & The Articulated Finger Revolution

WM Doll was one of the first TPE manufacturers to introduce articulated finger skeletons with true joints (as opposed to simple steel wires), dramatically improving the realism of hand gestures and gripping capability. The brand’s EVO skeleton system—provided as standard on all Jinsan-manufactured dolls—enables a full range of natural human poses, including flexible spine movement, shoulder articulation, and durable steel-gear joints that maintain poseability over years of use. For users who prioritize ease of handling, WM Doll offers MLS (M-Light Skeleton) weight reduction technology on select models, with fully standing skeletons also available (featuring three bolt holes in the soles for stable posing).

ROS Movable Jaw Technology & SS Silicone Head Series

WM Doll’s ROS (Real Oral Structure) upgrade transforms select heads into fully functional oral companions. The ROS system includes a movable jaw, realistic silicone teeth, a flexible tongue, and an anatomically detailed oral cavity with approximately 10 cm depth. While ROS compatibility is gradually rolling across WM Doll’s extensive head catalog—which exceeds 400 different face sculpts—the SS series silicone heads feature ROS upgrades by default, including built-in tongue and teeth as standard equipment. Optional add-ons for ROS heads include heating function, suction capability, and even an electronic moving tongue. WM Doll’s naming convention follows a systematic pattern: body heights are denoted by numbers (e.g., WM-156/E, WM-166/C, WM-172/D, WM-188), while heads are numbered sequentially (#S10, #182, SS196, etc.).

Standard Inclusions & Customization Depth

When purchasing from authorized WM Doll retailers, customers typically receive significant added value as standard. Common free inclusions with Jinsan-manufactured dolls include: a second interchangeable head, EVO skeleton (the older standard skeleton is no longer supplied), implanted pubic hair, a USB warming rod, a hanging storage kit, and a half-twist/half-push head connector system for easy head swaps. Customization options span dozens of categories: body type (from petite 140cm to full-sized 172cm and 188cm), breast size and shape (including gel, hollow, or solid options), skin tone (light, natural, tan, ebony), eye color (blue, brown, green, hazel, and custom colors), wigs or implanted hair (head, eyebrows, eyelashes, pubic area), and makeup styles ranging from natural to dramatic. WM Doll also offers heating systems that warm the doll’s skin to body temperature for enhanced intimacy.
