Product Overview and Application Fields
Multi level stepped ceramic structural components are made of high-performance engineering ceramics (such as alumina Al ₂ O ∝, zirconia ZrO ₂, silicon nitride Si ∝ N ₄, etc.) as raw materials, and are formed by dry pressing, injection molding, or casting, followed by high-temperature sintering, and then CNC precision machining to form multi-level stepped components. It combines the characteristics of high hardness, good wear resistance, low thermal expansion coefficient, strong insulation, and excellent chemical stability of ceramics, while achieving precise positioning, layered sealing, or composite assembly functions through multi-level step design.

Typical application scenarios include:
-Semiconductor manufacturing: used for wafer transfer robotic arms, vacuum chamber positioning steps, etching equipment insulation brackets, etc.
-Optics and Laser: As a lens adjustment ring and laser resonant cavity step base, it ensures the accuracy of optical path alignment.
-Medical devices: applied to high-precision surgical instrument guides, ceramic guides for imaging equipment, etc.
-Automation and measurement: used as precision bearing seat, sensor isolation gasket, detection instrument positioning block, etc.

Core advantages of the product

1. Ultimate precision and stability
   After sintering, ceramic materials have almost no internal stress and are not easily deformed. They can achieve long-term dimensional stability in multi-level stepped structures and are suitable for high-precision alignment and repeated assembly.
2. Excellent environmental adaptability
   -High temperature resistance: Alumina ceramics can work in an environment of 1500 ℃ for a long time, while zirconia ceramics can withstand temperatures of over 800 ℃.
   -Corrosion resistance: Excellent resistance to acids, alkalis, and organic solvents, suitable for chemical and electroplating environments.
   -Long wear life: The hardness can reach HRA85 or above, and the wear rate is only 1/10 of alloy steel.
3. Function integration design
   The multi-level step structure can replace multiple component combinations, reduce assembly steps, lower cumulative tolerances, and improve overall equipment reliability.

Customer Application Case (Anonymous)
-Case 1: A semiconductor equipment manufacturer
The original stainless steel step positioning component experienced slight deformation in a vacuum high-temperature environment, resulting in wafer alignment deviation. After replacing with our company’s zirconia multi-stage step ceramic parts, there was no displacement after 6000 hours of continuous operation, and the product yield increased by 2.3%.
-Case 2: A precision optical enterprise
We need a stepped insulation positioning seat for UV laser modules, which is required to be resistant to UV aging and have a size error of ≤ 0.015mm. We use high-purity alumina to customize a dual step structure and perform surface refinement treatment. After delivery, the customer feedback shows that the assembly efficiency has been improved by 40%.
-Case 3: A certain medical device company
Developing a new type of image detection device requires non-magnetic and biocompatible guide components. We design zirconia ceramic multi-level step guide rails to achieve magnetic interference free and smooth movement, and the product has passed FDA related testing.
