Zirconia Injection-Molded Threaded Rods

Zirconia injection-molded threaded rods are high-performance precision fasteners manufactured using the advanced ceramic injection molding (CIM) process. Made from yttrium-stabilized zirconia (Y-TZP) as the base material and produced through high-pressure injection molding, they enable the high-precision, near-net-shape production of custom-shaped ceramic components with complex external threads. Combining high fracture toughness, excellent wear resistance, and outstanding electrical insulation properties, this product is an ideal alternative to traditional metal fasteners.

From the user’s perspective, this zirconia threaded rod precisely addresses the many challenges you face under extreme operating conditions. When your equipment is exposed to highly corrosive environments, high temperatures, or requires strict electrical insulation, traditional metal fasteners are highly susceptible to rust, electrical conductivity, or fatigue failure. Our product not only offers exceptional impact and bending resistance but also maintains structural stability in environments with strong acids, strong alkalis, and high temperatures, completely resolving the issues of fastener fragility, short service life, and equipment failures.

Core Advantages and Customization Services
As a prime example of modern powder injection molding technology, zirconia injection-molded threaded rods demonstrate significant advantages in both manufacturing processes and material performance. Thanks to high-pressure injection molding, the green compacts have extremely uniform density, and the dimensions of the sintered products are precisely controllable, with tolerances as tight as 0.1%–0.2%. This near-net-shape process requires little or no machining, which not only significantly reduces manufacturing costs but also allows for the easy production of complex, irregularly shaped parts featuring transverse holes, angled holes, convex and concave surfaces, and precision threads.
In terms of material properties, zirconia ceramics demonstrate exceptional overall performance. With a flexural strength as high as 900–1,200 MPa and a fracture toughness of 7–10 MPa·m¹/², their strength and toughness are 3–4 times that of traditional alumina ceramics. In addition, it offers excellent wear resistance, outstanding surface finish, and superior electrical insulation (resistivity ≥ 10¹⁰–10¹² Ω·cm), and can withstand high temperatures of approximately 1000°C in air.
To meet a wide range of demanding industrial and research requirements, we offer comprehensive customization services for specifications and dimensions. Whether it’s metric threads from M3 to M16, imperial threads, standard lengths from 20–200 mm, or even tighter tolerance requirements, we can tailor our products exclusively to your specific drawings.

Typical Applications and Benefits
In the fields of semiconductor and electronic engineering, zirconia threaded rods—thanks to their non-conductive and non-magnetic properties—effectively resolve electromagnetic interference issues during the assembly of sensitive electronic components, making them the preferred choice for high-precision insulated fasteners. In medical and dental equipment, their excellent biocompatibility, corrosion resistance, and MRI-safe properties effectively address the biocompatibility challenges faced by surgical instruments and implants in the complex human body environment. Furthermore, in aerospace, precision machinery, and laboratory equipment, these rods successfully overcome fastener failure issues in extreme environments thanks to their outstanding vibration and shock resistance, as well as chemical inertness, providing users with long-term, highly reliable performance.
