1. A method of debinding using a binder trap system having at least two binder traps by removing binder from binder laden gas evacuated from a sintering furnace, comprising:
cooling the contents of at least one of the binder traps receiving the binder laden gas in order to condense the binder from the binder laden gas inside the binder trap being cooled as the binder laden gas flows through the cooled trap so that the cooled trap retains the binder from the binder laden gas;
isolating at least one binder trap that has been cooled so that gas flowing from furnace bypasses the isolated binder trap, allowing gas flowing from furnace to continue to flow to other binder traps without shutting down the furnace;
switching from cooling the isolated trap to heating the isolated trap for melting the binder in the trap and allowing the melted binder to drain; and
switching the isolated trap back to receiving binder laden gas from the furnace, so that another binder trap may be isolated.
