Ensuring the safety of sex dolls is a critical part of manufacturing that involves multiple rigorous testing processes. Manufacturers start by selecting high-quality, body-safe materials such as medical-grade silicone or TPE, which are tested for non-toxicity and hypoallergenic properties. These materials undergo chemical analysis to confirm they do not emit harmful substances or volatile organic compounds (VOCs). Mechanical safety is also a priority; joints and movable parts are tested for durability and stress resistance to prevent breakage or injury during use. Manufacturers conduct stress tests by simulating extended use, checking for wear and tear over time. To ensure hygiene and safety, dolls are designed with removable and washable components, and their internal structures are tested for mold and bacterial growth resistance. Additionally, safety standards include electrical safety if the doll features electronic components like voice or movement functions. These components are subjected to electrical safety testing, ensuring they meet international safety standards for moisture resistance and electrical integrity. Quality control checks are performed at multiple stages, from raw materials to finished products, to ensure consistency. Ethical testing also involves user safety education, providing guidelines for safe handling and cleaning. Overall, the comprehensive testing process guarantees that sex dolls are safe, durable, and reliable for consumers.
