Abstract:
1. An inflator processing apparatus comprising a processing furnace for processing inflators, said apparatus being configured to process a batch of gas generating chemical-containing automobile air bag inflators, each said inflator comprising a metal case, by heating the inflators to a temperature not lower than an explosion temperature of the chemical and subsequently recovering the metal cases of the inflators, wherein a metal partition wall composed of heat-resistant steel is provided, between the inflators and an inner surface of a ceramic wall of the processing furnace for processing the inflators, so as to cover the inner surface of the wall of the processing furnace and to prevent the inflators, when actuated by heating, from striking and damaging the inner surface of the ceramic wall of the processing furnace, said inflator processing apparatus further comprising a module for charging the apparatus with a batch of inflators, in which module a timing of charge of the batch of inflators is judged by comparing a total number of charged inflators located in the apparatus with an observed number of peak points of furnace pressure due to explosion of the chemical in the charged inflators located in the apparatus.
