Custom Sapphire Triangular Component with High-Precision Through-Hole

Custom Sapphire Triangular Component with High-Precision Through-Hole

Product Introduction

Our Custom Sapphire Triangular Components are engineered for high-end industrial applications requiring extreme mechanical strength, thermal stability, and chemical resistance. Manufactured from 99.9% high-purity single-crystal sapphire (Al₂O₃), these components feature a unique triangular geometry with precision-drilled through-holes.

This product is ideal for applications such as semiconductor wafer handling, high-pressure viewports, and optical sensors, where standard glass or ceramics cannot meet performance requirements.

Technical Manufacturing Capabilities

To ensure your design is optimized for manufacturing, we provide the following specifications for our sapphire processing:

Notes:

• Triangular geometry and through-hole positions can be fully customized according to CAD or STEP drawings.

• High reproducibility ensures consistent quality for industrial applications.

Key Performance Advantages

• Extreme Hardness: Mohs 9 hardness ensures superior scratch resistance and durability in abrasive environments.

• High Thermal Resistance: Maintains structural integrity at extremely high temperatures, ideal for demanding industrial and semiconductor applications.

• Broad Optical Transmission: High transparency from UV (190 nm) to Mid-IR (5000 nm), supporting a wide range of optical applications.

• Chemical and Plasma Resistance: Excellent durability in corrosive or plasma-rich environments.

• Zero Outgassing: Suitable for Ultra-High Vacuum (UHV) and cleanroom processes.

Typical Applications

• Semiconductor Industry: Plasma-resistant triangular support plates, wafer positioning pins, and precision alignment fixtures.

• Fluid Precision Systems: Micro-orifices (0.2 mm) for high-pressure chemical nozzles or waterjet applications.

• Optical Systems: Triangular prisms, precision window mounts, and components requiring high optical clarity.

• Aerospace & High-Temperature Sensors: Extreme-pressure viewing windows and high-temperature optical sensor housings.

Frequently Asked Questions (FAQ)

Q1: What is the smallest hole diameter you can achieve in a sapphire triangular component?
We can precisely machine holes down to 0.2 mm with a tolerance of ±0.01 mm using advanced ultrasonic or laser drilling. The resulting hole walls are smooth and free of chipping.

Q2: Can the triangular shape and hole positions be customized?
Yes. We offer full customization of triangle geometry (equilateral, right-angle, or other types) and exact hole locations. CAD, STEP, or PDF drawings can be submitted for feasibility evaluation.

Q3: How do you ensure high surface quality and flatness?
Each component undergoes rigorous inspection using interferometers and optical comparators. We guarantee Scratch/Dig 20/10 per MIL-PRF-13830 standard and surface flatness up to λ/10 @633 nm, suitable for high-precision optical paths.

Q4: Why choose sapphire over fused quartz or alumina ceramics?
Sapphire provides superior mechanical hardness, thermal resistance, plasma and chemical durability, and broad optical transmission, making it ideal for extreme conditions where other materials fail.

Q5: What if my design exceeds standard specifications?
We frequently work on R&D and custom projects with challenging geometries. If your design falls outside listed parameters, please contact us — we can often provide solutions for unique or "impossible" requirements.
