TiB2 BN Boron Nitride Ceramics Evaporation Boat for PET Metallization | 12-24 Hour Life | <1850°C Temperature
TiB2 BN Boron Nitride Ceramics Evaporation Boats are engineered for PET metallization applications, offering exceptional high-temperature performance and electrical insulation properties in demanding industrial environments.
- Automotive, electronics, and electrical engineering sectors
- Aerospace, medical science, and scientific research applications
- Extreme environments requiring electrical insulation and thermal resistance
- High-temperature operations with chemical resistance capabilities
- Resistance-heated boats operate in vacuum chambers at 1500-1650°C (2732-3002°F)
- Evaporates various metals including aluminum, copper, tin, and silver
- Used for metallized films and papers in food packaging, capacitor films, decorative, and electronic industries
- Verify alignment and smooth surface of electrical contacts
- Utilize graphite tape for uniform electrical and thermal contact
- Employ aluminum wire pieces for initial temperature calibration
- Position wire feed centrally on boat surface
- Follow 12-14 minute heat-up cycle for proper reannealing
- Begin with 75% normal wire feed rate and adjust power for optimal wetting
- Gradually increase wire feed rate during first 15 minutes of production
- Post-coating: stop wire feed first, then cut power after 20-30 seconds
- Allow 2-minute cooling period before vacuum release
- Clean boats with wire brush after each cycle
