Buyer's Guide

How to Choose AI Furnace Series for Your Dental Lab

Dental sintering and porcelain furnaces finalize zirconia and ceramic restorations. The AI-S8 sinters compatible blanks in 30-45 minutes, while the AI-A7 handles porcelain staining and glazing — both with ±1 °C control for consistent results.

🔥Sintering zirconia

  • AI-S8: fast sintering ~30-45 min for compatible blanks.
  • Up to 1600-1700 °C with controlled ramp/cool.
  • Pre-stored curves simplify daily operation.
  • Validate fast cycles on a test batch first.

🏺Porcelain & ceramic

  • AI-A7: porcelain/ceramic furnace for staining & glazing.
  • 100 pre-stored roasting curves.
  • ±1 °C control for repeatable aesthetics.
  • Touch-screen, easy program selection.

🔧Maintenance

  • Calibrate temperature against a reference pyrometer.
  • Keep a maintenance log per service schedule.
  • Replace heating elements as recommended.
  • Ensure stable power (AC 220V 50Hz).

Periodic temperature calibration keeps shrinkage consistent; always validate fast sintering cycles on a test batch before production runs.

FAQ

Product FAQ

How fast can Birfair furnaces sinter zirconia?
The AI-S8 supports fast sintering in roughly 30-45 minutes for compatible blanks; the A7 is a ceramic/porcelain furnace for staining and glazing. Always validate fast cycles on a test batch.
Do furnaces need regular calibration?
Yes — periodic temperature calibration against a reference pyrometer keeps shrinkage consistent. Keep a maintenance log and replace heating elements per the service schedule.
