Our two-station sintering furnace is based on our bottom loading sintering furnace, but is capable of simultaneously processing two loads, essentially doubling throughput within the same footprint. Our sintering furnaces are widely found in the electronics industry for sintering or heat treating electronic components at high temperatures. Cycles consist of atmosphere preparation, heating, rapid cooling and controlled oxidation.

The two-station furnace handles two loads simultaneously by heating one load in the hot chamber while cooling the second one in the bottom chamber.

This furnace has a usable zone of 12” diameter x 22” high (305 mm x 559 mm), and is suited for large batch processing.

The furnace features two chambers, a bottom chamber for loading and unloading, cooling and controlled oxidation, and the top chamber for sintering. Both chambers’ atmospheres are isolated. An electric lift moves the load stacks from the bottom chamber into the heating chamber.

The hot zone is capable of temperatures up to 2100°C with Tantalum or Tungsten hot zones..

A high throughput 10″ or 16″ diffusion pumping system handles load outgassing typically seen during product heat-up.

An intuitive customized HMI interface runs completely automated cycles start to finish.

Load Lift System

Our two-station furnace sintering furnace is identical to our single-station bottom-loading sintering furnace, with the exception of the load lift system and the control software. As this furnace handles two loads simultaneously, it has two electrical load lifts for vertical movement and additional servo motors to rotate the load arms horizontally.

This mechanism is able to switch loads internally without operator assistance. When the heat cycle in the top chamber is complete and a new load is ready for sintering, the top load stack will lower into the bottom chamber, and the new load will be lifted into the top chamber.

The newly-lowered hot load is then cooled in the bottom, undergoes controlled oxidation, and is unloaded when ready. The servo system also rotates the load arms of the bottom chamber to facilitate loading and unloading.

A load lift for the load support arm acts as both a transfer mechanism and vacuum seal between the top and bottom chamber.
