4. Application
As the heat-shield parts in the sapphire growth furnace, the most decisive function of upper and bottom cover plate is to prevent and reflect the heat in the furnace. Heat-shield parts with high-density, exact-measurement, smooth-surface, convenient-assembly and reasonable-design has great significance in improving the crystal-pulling.
5. Advantage of our W/Mo reflection shield
- long term stock for your ready choice
- bright and chemically cleaned surface with quality.
- uniform grain with densified microstructure ensures longer use time.
- precise machining tolerance.
- professional after-sales service
