Machining & Sheet Metal Fabrication

Siana-Tech provides precision machining and sheet metal fabrication services for mechanical components, machine structures, assemblies, and production parts.

Our capabilities include multi-axis CNC milling, CNC turning, combined milling and turning operations, EDM, wire cutting, bending, pressing, guillotine cutting, and the manufacturing of mechanical structures and assemblies.

These capabilities support both prototype development and serial production, allowing customers to move from engineering design to reliable manufacturing with controlled quality, repeatability, and production efficiency.


Advanced Ceramic Components for Semiconductor Applications

Siana-Tech supports the manufacturing of advanced ceramic components for semiconductor, precision engineering, and high-performance industrial applications. 

These components are selected for applications that require high hardness, wear resistance, dimensional stability, thermal resistance, chemical resistance, and electrical insulation.

Typical ceramic materials include silicon carbide, alumina, aluminum oxide, silicon nitride, and zirconia. Each material is selected according to the required operating conditions, including temperature, mechanical load, chemical exposure, electrical properties, surface finish, and dimensional accuracy.

Ceramic components can be used in wafer handling, positioning systems, insulating parts, wear-resistant inserts, precision fixtures, and other applications where conventional metallic or polymer materials may not provide sufficient performance.

Materials and Typical Properties

Silicon Carbide — SiC

Silicon carbide is a high-performance technical ceramic known for high hardness, excellent wear resistance, good thermal conductivity, low thermal expansion, and strong thermal shock resistance. It is suitable for precision components exposed to demanding mechanical and thermal conditions.

Alumina / Aluminum Oxide — Al₂O₃

Alumina is widely used for ceramic components requiring high hardness, wear resistance, corrosion resistance, electrical insulation, and good dimensional stability. High-purity alumina grades are commonly used in semiconductor, electrical, and precision industrial applications.

Silicon Nitride — Si₃N₄

Silicon nitride offers high strength, fracture toughness, wear resistance, low density, and excellent resistance to thermal shock. It is suitable for applications involving mechanical stress, temperature variation, and precision movement.

Zirconia — ZrO₂

Zirconia is a tough technical ceramic with high mechanical strength, wear resistance, corrosion resistance, and good dimensional stability. It is often selected for precision parts that require higher toughness compared with many other ceramic materials.

Manufacturing Focus

Our ceramic component support may include material selection, precision machining, grinding, polishing, dimensional inspection, and production coordination according to customer drawings, specifications, and application requirements.
