This product is an irregular perforated alumina ceramic precision component, manufactured from high-purity alumina (Al₂O₃) ceramic raw materials via precision machining. It features a smooth surface, ultra-tight dimensional tolerances, and a perforated plate-like structure. Designed specifically for semiconductor, photovoltaic, and other precision equipment, it serves as a vacuum suction plate, positioning fixture, or wear-resistant structural component to meet demanding industrial working conditions.
Applications
Widely used in semiconductor wafer handling, photovoltaic cell processing, precision optical component positioning, lithium battery tab welding, and other scenarios. It can also be used as an insulating and wear-resistant structural part in automated equipment to achieve damage-free adsorption and stable clamping.
Core Advantages
Ultra-high Hardness & Wear Resistance: Mohs hardness 9, with excellent wear and impact resistance, offering a far longer service life than metal parts.
Insulating & Corrosion Resistant: Outstanding insulating properties and chemical inertness, resistant to acid and alkali corrosion, suitable for clean production environments.
Low Thermal Deformation: Low thermal expansion coefficient, ensuring strong dimensional stability at high temperatures to maintain processing accuracy.
Precision Machining: Hole and form tolerances controlled within ±0.01mm, compatible with high-precision automated equipment.

Instructions for Use
Clean the product surface before installation to avoid dust residue affecting adsorption performance.
When connecting to equipment, ensure the sealing ring is intact to guarantee vacuum line sealing.
Avoid severe impact to prevent brittle cracking of the ceramic.
Regularly check the patency of holes and promptly clean any clogged impurities.
After-Sales Service
Customization of sizes and hole designs is available, with free sampling services provided.
All products undergo full inspection before delivery, with inspection reports provided. Non-human-induced quality issues are eligible for return or exchange.
Technical support is available to assist customers with equipment adaptation and process optimization.
Frequently Asked Questions
Q: Can the product be customized?
A: Customization according to drawings or samples is available, including adjustments to dimensions, hole positions, and alumina content.
Q: Will the surface scratch workpieces?
A: After high-precision polishing, the surface is smooth and burr-free, and will not scratch precision components.
