At its core, a cock ring (also known as a constriction ring) is a device designed to optimize hemodynamic stability. By applying a calibrated amount of pressure to the base of the penis, it restricts venous outflow while allowing arterial inflow. This leads to increased engorgement, enhanced rigidity, and prolonged duration of physical performance.
Modern engineering has evolved basic rings into neuro-stimulatory devices. By integrating micro-motors (vibration technology), these rings provide localized stimulation to both the wearer and their partner, addressing sexual wellness from a holistic perspective.
Beyond recreation, these devices are utilized in clinical settings for managing mild erectile dysfunction (ED) and as part of post-operative recovery protocols, emphasizing the need for medical-grade silicone compliance.
TOPARC TECHNOLOGY (SHENZHEN) CO., LTD. was established in July 2008 with a registered capital of HK$18 million. It is a modern Hong Kong-funded enterprise integrating the research and development, production, sales and service of sexual aids and sexual health products.
Our manufacturing base covers an area of 10,000 square meters in Shenzhen. We are a national and Shenzhen Double High-tech enterprise with ISO 9001, ISO13485, BSCI, CE, FCC, ROHS, and FDA certifications.
Our main products are Sexual Aid devices, Sexual Health devices, Massage equipment, Personal Health Care appliances, Postpartum Repair equipment and more.
Leveraging Shenzhen's unique ecosystem, TOPARC provides unparalleled manufacturing agility. From raw material sourcing to SMT assembly, we represent the peak of China's industrial efficiency.
We also provide our clients with OEM and ODM services. We have a robust R&D team including ID Designer, mechanical Engineer, software Engineer, and electronic Engineer. We have one-stop service capability from design to production.
Armed with a first-class mold manufacturing center (CNC EDM machines), we produce high-quality hardware. Our silicon formation and silicon injection molding production lines produce the necessary biocompatible components.
We have SMT production technology and can independently produce PCB with unique functions. We have self-developed motor technology to provide the power core for adult products.




The global male wellness market is shifting from "taboo" to "mainstream health." Retailers in North America and Europe are demanding products that look like medical technology rather than traditional adult toys.
The next frontier is Internet of Things (IoT) integration. TOPARC is already researching biometric feedback rings that track stamina, heart rate, and performance metrics, providing actionable data to users.
Factories must now prove sustainability. Our facility utilizes energy-efficient injection molding and focuses on recyclable packaging to meet EU Green Deal standards.

We deeply understand the importance of product inspection and test, we conduct full inspections and continuously improve product performance through test. We have aging testing, IPX7 waterproof testing, button life testing and battery comprehensive testing.
A: Medical-grade, platinum-cured silicone is the gold standard. It is non-porous, hypoallergenic, and can be sterilized, unlike TPE or vinyl which may contain phthalates.
A: We utilize vacuum pressure immersion tanks where products are submerged at 1-meter depth for 30 minutes. This ensures safety and longevity during cleaning and aquatic use.
A: Yes. Our in-house software engineers can program custom IC chips with specific frequencies, from steady pulses to complex escalating patterns, ensuring brand differentiation.
A: For a complete ODM project (from ID design to mass production), our typical timeline is 60-90 days, facilitated by our in-house CNC mold center.
