Brief Description:
To achieve high densities and remove gases and impurities, with
pre-sintering and binder removal MIM vacuum dewaxing, sintering
furnace can be accomplished in a gas atmosphere where the retort
gas outlet will remove binders or other out-gassing product
without allowing them to contact the heating element and zone,
while at the same time improving temperature uniformity. The
actual sintering process can be accomplished in a high vacuum
atmosphere or in gas to remove all contaminants from the product.
This construction guarantees that the parts are fully debound
through the even gas flow during the debind cycle and sintered
to full density through the close temperature. All controls
for flow, temperature, and partial pressure are fully computerized
and automatic. All operating data such as temperature, gas flow,
pressure, total power and gas consumption, is logged for each
run.
This type of furnace completes controlled economical production
and high quality and is a suitable efficient method as well.
