With indirect resistance heating technology, the mold is placed in a heating chamber.

"I'm putting a higher vacuum on the heating chamber."

The heating chamber was not a cooking oven, it was a kiln.

The retort consists of a series of connected individual heating chambers, stacked atop each other.

The paper is then soaked in phenolic resin and goes up to a heating chamber to be dried out before being rolled back up.

They altered the heating chamber and eliminated the recessed well which was hard to clean.

This process can be further improved by changing the aluminum construction of most heating chambers to a metal with superior heat transfer qualities, such as copper.

Because of the smaller heating chambers, there is a saving in heating costs compared to bi-axial machines.

Most shuttle machines hve two arms that moves the molds back and forth between the heating chamber and cooling station.

A conveyor furnace uses a flexible metal belt to convey soil through the primary heating chamber.
