Product Features
Diverse material adaptation: Plastic materials are selected from medical-grade POM, ABS, etc., which have the advantages of light weight, good insulation and low cost, and are suitable for portable devices that are sensitive to weight; metal materials are 316L stainless steel. After blackening treatment, it is not only rust-proof and wear-resistant, but also has high strength and good biocompatibility, which is suitable for key parts that bear greater pressure.
Excellent protection performance: The black surface treatment process gives the components excellent protection capabilities. The antibacterial coating on the surface of plastic parts can inhibit the growth of bacteria; the blackening coating of metal parts can effectively resist the erosion of disinfectants and acidic and alkaline substances in the medical environment, and pass the 96-hour salt spray test to extend the service life.
High-precision design and manufacturing: Using precision injection molding or CNC machining technology, the component size accuracy is controlled within ±0.05mm, the annular protrusion and the groove are tightly matched, and the coaxiality error of the center circle hole is ≤0.02mm, ensuring precise assembly with other equipment components and ensuring the stability and accuracy of medical equipment operation.

Multifunctional application features: The annular protrusion and groove design can realize quick snap-on connection and sealing between components to prevent liquid leakage and dust intrusion; the center circular hole can be used as an installation position or fluid channel for shaft parts to meet the diverse functional requirements of medical equipment transmission and circulation.

3. Product Details
Material and process: Plastic parts are made of medical-grade POM or ABS raw materials, and are molded by high-precision injection molding with a mold precision of micron level to ensure the stability of product dimensions; after molding, the surface is treated with antibacterial treatment to improve hygiene performance. Metal parts are made of 316L stainless steel, which is blackened after forging and CNC processing to increase surface hardness and rust resistance. Some parts can also be electropolished to make the surface roughness Ra≤0.4μm.
Specifications and customization: A variety of standard specifications are provided, with a diameter range of 10mm - 100mm and a thickness of 2mm - 15mm. Customized services are supported, and materials, sizes, surface treatment methods can be adjusted according to customer needs, as well as special structural designs (such as adding positioning pin holes and threaded holes) to meet the personalized needs of different medical devices.
Application scenarios: In medical testing equipment, it is used as the core component of sample trays and reagent turntables to achieve accurate transmission of samples and reagents; in medical imaging equipment, it is used to fix lenses and detectors to ensure the coaxiality and stability of optical components; in surgical instruments, it is used as joint connectors and knobs to help doctors perform delicate operations. In addition, it can also be used in the outer shell sealing cover of medical equipment to prevent dust and liquid from invading the interior of the equipment.
