First introduced in 1997, the Gasbarre automatic die wall lubrication
system is now being used in a wide variety of applications, the
company reports. The main thrust of the development was to reduce or
eliminate internal lubrication of iron based materials for higher
green densities and to eliminate the problems associated in the
removal of these lubricants in the sintering furnace. According to
the company, the most common application is for the increase of
magnetic properties associated with the reduction of porosity through
the reduction of internal lubricant levels of the powder blend.
Through the reduction (or elimination) of internal lubricants, higher
densities can be achieved, which raises the maximum permeability and
lowers the coercive force of these magnetic components.
