PVD Coating Equipment Maintenance: Extend Lifespan

In the precision manufacturing industry, PVD Coating Equipment (Physical Vapor Deposition Coating Equipment) is a core tool for enhancing product surface performance. However, its high precision and complex structure mean that neglecting maintenance can lead to reduced efficiency, increased costs, or even equipment failure. This guide provides comprehensive maintenance tips to help you maximize equipment performance and minimize operational risks.

1、Daily Maintenance: Details Determine Equipment Lifespan

Lubrication and Cleaning Management

• Check vacuum pump oil levels monthly, and change oil every two weeks during the rainy season.
• Clean the vacuum chamber walls with a caustic soda solution after every 200 coating cycles to remove residual film materials.

Operational Monitoring

• Daily checks should include mechanical pump oil levels, diffusion pump vacuum levels (target: 6×10⁻² Pa), and key parameters like current and voltage.
• Immediately shut down and inspect the equipment if bearing jams or unusual noises are detected.

Safety Protocols

• Always hang a “Under Maintenance” sign and disconnect power before repairs to ensure safety.

2、Periodic Maintenance: Key Steps for Preventive Care

Diffusion Pump System Maintenance

• Check diffusion pump speed every six months. If efficiency drops, disassemble and thoroughly clean the pump.
• Replace diffusion pump oil every 1.5 years to avoid unexpected failures.

Sealing and Leak Detection

• Regularly inspect seals on vacuum chamber doors and pipe connections. Replace with high-temperature-resistant materials if damaged.

Data-Driven Maintenance Strategy

• Maintain equipment logs to track installation parameters, major repairs, and daily inspections. Use historical data to predict component lifespan.

3、Why is Maintaining PVD Coating Equipment Crucial?

• Cost Savings: Regular oil changes prevent costly downtime caused by diffusion pump failures.

• Quality Assurance: A clean vacuum environment reduces film impurities, improving product yield.

• Compliance: Reducing equipment failures minimizes energy waste and harmful emissions, aligning with ESG standards.
