Sintering Furnace Batch Throughput Optimization

Throughput is not about a bigger furnace — it is about filling the one you have without crowding it.

The crowding trap

Stacking discs edge-to-edge blocks heat flow; centre discs sinter hotter than edge discs, widening shade and shrinkage variation. Keep one disc-width gap between stacks.

Squeeze more through

• Batch by peak temperature — mixing 1450 and 1530 °C grades forces a compromise curve.
• Use a fast-debind program for thin smile-arch bridges.
• Pre-heat the next tray while one sinters.

Rough capacity maths

A 90 mm tray holds ~12单层 crowns; two stacked trays double output with no extra footprint, if your furnace allows stacking.

See stacking guidance for the AI Furnace Series.

Double throughput without a second furnace

Most furnaces sit idle 40% of the day between cycles. Stage trays so one cools while the next heats: a 6-hour program plus a 1-hour load swap gives near-continuous runs.

Loading rules

• Keep 5 mm between pucks; crowding slows the thermal soak.
• Put the same shade on one tray — different shades want different peaks.
• Never open above 200 °C; thermal shock cracks the muffle.
