Al2O3, Si3N4, and ZrO2 ceramic dowel rod pins from Xiamen Unipretec Ceramic Technology Co., Ltd. are precision-engineered components designed for high-wear and high-temperature applications. The supplier offers a range of ceramic compositions, including 92%, 95%, 96%, 99%, 99.5%, and 99.8% alumina, with 95% and 99% being the most commonly used for dowel pins. Silicon nitride (Si3N4) and zirconia (ZrO2) variants are also available, each tailored for specific mechanical and thermal demands.
Alumina ceramics provide excellent electrical insulation and wear resistance, making them ideal for use in electronics, pump components, and automotive sensors. Silicon nitride offers superior thermal shock resistance and fracture toughness, while zirconia stands out for its high strength and flexibility, often referred to as ceramic steel due to its resistance to crack propagation.
These dowel rod pins are used in industries where precision, durability, and resistance to corrosion or thermal stress are critical. Buyers typically specify material composition, dimensions, and surface finish to match their application’s tolerances. The supplier’s manufacturing techniques include uniaxial pressing, isostatic pressing, injection molding, and extrusion, with finishing achieved through precision grinding or laser machining.

Before ordering, confirm the exact material composition and its suitability for your application’s environmental conditions. For instance, verify whether the alumina grade (e.g., 95% vs. 99%) meets the electrical insulation or wear resistance requirements of your design. Request material test reports to validate key properties like density and fracture toughness.
Discuss logistics details such as lead time, preferred Incoterms (e.g., FOB Xiamen), and packaging to prevent damage during transit. Ceramic components are brittle, so ensure the supplier uses appropriate cushioning and protective packaging. Xiamen’s port infrastructure facilitates efficient shipping for international buyers.
Conduct quality checks upon receipt, including dimensional inspections and visual examinations for surface defects. For critical applications, perform additional tests such as hardness testing or non-destructive evaluation (NDE) to confirm the material’s integrity. Request documentation such as material certificates, test reports, and compliance declarations to ensure traceability and quality assurance.
