Artificial hand

Buyers must distinguish between prosthetic functional hands and aesthetic display hands. For functional prosthetics, prioritize myoelectric sensors, multi-grip patterns, and high-torque micro-motors. For display or medical training hands, focus on platinum-cured silicone for a realistic skin texture and internal wire armatures that allow for multi-angle posing. Ensure the durometer (hardness) of the material matches the intended use case, typically ranging from 20A to 40A on the Shore scale.

If the product is for medical use, it must comply with ISO 13485 (Quality Management for Medical Devices). For the US market, FDA Class I or II registration is required, while the EU market necessitates CE Marking under the Medical Device Regulation (MDR 2017/745). For non-medical display hands, ensure materials are REACH or RoHS compliant to guarantee they are free from hazardous phthalates and heavy metals.

Request tensile strength test reports to ensure the silicone or TPE does not tear under stress. For mechanical hands, ask for cycle testing data (e.g., 100,000 open-close cycles) to verify motor longevity. It is critical to confirm the UV resistance of the outer skin to prevent yellowing or degradation over time, especially for display models exposed to retail lighting.

Top-tier suppliers on Made-in-China.com should offer OEM/ODM services including custom skin tone matching using Pantone references, size scaling based on 3D scans, and integrated mounting hardware (e.g., M8 or M10 threaded inserts). For bionic versions, look for suppliers capable of firmware customization for specific gesture controls.

Always utilize Secured Trading Services provided by Made-in-China.com to ensure payment is only released upon confirmation of receipt. For large orders, hire a third-party inspection agency (like SGS or Intertek) to perform a Pre-Shipment Inspection (PSI) to verify that the technical specifications match the approved sample.

Focus on Total Cost of Ownership (TCO) rather than just the unit price. Negotiate for spare parts kits (extra silicone skins, batteries, or joints) to be included in the bulk price. Request a tiered pricing structure where the unit cost drops by 10-15% as volume increases from sample size to full container loads.

Artificial hands, especially those with electronics or delicate silicone, require anti-static packaging and custom-fit foam inserts to prevent deformation during transit. Ensure the shipment is marked as 'Fragile' and consider climate-controlled shipping if the route passes through extreme heat zones, which can affect silicone stability.

Verify the correct HS Code (typically 9021.39 for artificial parts of the body or 3926.90 for plastic display items) to avoid customs delays and incorrect duty applications. Ensure the supplier provides a Certificate of Origin to take advantage of potential Free Trade Agreements (FTAs) that could reduce import tariffs.
