About

About NIPPON PISTON RING Co., Ltd. Advance your next implantable or minimally invasive device with NPR’s nickel‑free NiFreeT™ alloy, titanium MIM components, and DLC/TiN coatings, backed by ISO 13485–certified manufacturing and practical device‑maker insights from Japan. Nippon Piston Ring Co., Ltd. develops NiFreeT™, a nickel‑free titanium‑tantalum‑tin alloy engineered for biocompatibility, low Young’s modulus, high elastic limit, non‑magnetic properties and strong X‑ray visibility for long‑term implantable devices. Target applications include orthopedic devices, dental screws, guidewires and catheter components. Their METAMOLD® metal injection molding process delivers near‑net‑shape CP‑Ti and Ti‑6Al‑4V components (ASTM F2885) for small, complex geometries and scalable production. Device‑oriented surface engineering includes wear‑resistant, low‑friction DLC and TiN coatings; TiN electrodes can be textured with pyramid‑shaped micro‑features to increase capacitance. Metal 3D additive manufacturing (BJT) enables rapid, tool‑less prototypes and supports a smooth transition to MIM mass production. As an active dental implant manufacturer (IAT), NPR brings real‑world medical device experience to engineers and sourcing teams.
