Product Description

Product Name:
Ceramic Insert Tungsten carbide Core Needle

Product Overview: The ceramic insert Tungsten carbide core needle, designed as a high-end accessory for ceramic powder injection molding molds, is a precision needle tailored for the production of ceramic inserts in fiber optic connectors. With a high precision requirement of ±0.001 to ±0.0005, it meets the stringent precision requirements of ceramic insert products.
Material Selection: In the production of fiber optic connector insert cores using ceramic injection molding technology, the main material employed is zirconia ceramic, specifically yttria-stabilized zirconia (Y-PSZ) nanopowder. Zirconia ceramic exhibits characteristics such as high-temperature stability, excellent thermal insulation, and resistance to acid corrosion, making it an ideal choice for fiber optic connector ceramic inserts.
Process Characteristics: During the ceramic powder injection molding process for producing ceramic inserts, the ceramic insert Tungsten carbide core needle is required to have properties such as acid resistance, corrosion resistance, and high-temperature resistance. Tungsten carbide, as the core needle material, is capable of withstanding high-temperature corrosive environments, ensuring the long-lasting performance of the core needle in production operations.

Customization Services: Zhuzhou Sanxin Hard Alloy provides customization services for high-precision ceramic insert Tungsten carbide core needles, meeting customer requirements for precision tolerances in PIN needles. The customization process aligns with customer-provided drawings and requirements for ceramic powder injection molding molds.
Technical Requirements:
Precision Requirement: ±0.001 to ±0.0005
Material: Tungsten carbide
Ceramic Material: Yttria-Stabilized Zirconia Nanopowder (Y-PSZ)
High-temperature resistance, acid corrosion resistance, durable performance
Through the production process at Zhuzhou Sanxin Hard Alloy, this ceramic insert Tungsten carbide core needle can achieve large-scale, batch production in high-demand environments.
