Product Introduction
Micro-precision equipment often has extremely limited space, making standard thick-walled tubes unsuitable. Thin wall ceramic tubes are designed for ultra-thin, high-precision applications. Made from 99%–99.7% high-purity alumina, they are sintered with segmented temperature control to achieve wall thicknesses of only 0.3–1.0 mm, providing a lightweight, compact solution. With minimal thermal inertia, they heat and cool rapidly for precise temperature control. High coaxiality and micrometer-level dimensional accuracy, along with stability up to 1400℃ and excellent insulation, make them ideal for precision thermocouples, micro-heaters, medical insulation components, and small aerospace parts. Thin wall ceramic tubes are essential for micro-equipment, offering both space efficiency and durability.

Key Advantages
Lightweight and Highly Responsive: Ultra-thin walls and low weight result in minimal thermal inertia, enabling rapid heating and cooling, and precise integration with instruments for accurate temperature control.
High-Temperature Insulation and Stability: Dense, pure alumina maintains excellent insulation at 1300℃, eliminating risks of leakage, breakdown, or creepage, ensuring safe operation of precision electrical components.
High Precision and Strong Compatibility: Precision forming and grinding ensure uniform wall thickness, roundness, and straightness, providing excellent interchangeability and seamless integration with automated precision assembly lines.
Applications
Widely used with micro-heaters, precision thermocouple protective sleeves, high-temperature sensor components, medical insulation parts, laboratory analytical instruments, micro-insulation components for new energy devices, and small aerospace high-temperature parts. Suitable for precision electronics, medical devices, renewable energy, aerospace, and scientific research industries.
Thin Wall Sintering Technology
Our factory has overcome the challenges of thin-wall ceramic sintering using segmented temperature-controlled sintering, reducing shrinkage stress and minimizing warpage or cracking. This ensures defect-free appearance and structural stability across mass-produced batches.
Micrometer-Level Quality Control
Equipped with high-precision optical inspection instruments, each tube is measured for wall thickness, outer diameter, and roundness at the micrometer level. Defective units are filtered out to maintain strict tolerance standards, meeting the demanding assembly precision of micro-equipment.
Small Batch Customization
Supports non-standard micro-sizes and special wall thicknesses for niche precision instrument applications. Flexible small-batch prototyping with short lead times is available, alongside standard ready-to-ship sizes for both R&D and large-volume procurement needs.
