Mechanization of the process of core making with the use of inorganic
and organic binders is based, almost solely, on core blowing
machines. Presently the core blowing machines are equipped with tools and
devices that allow for application of different technologies
of core making. Cold-box, hot-box and warm-air technologies require that core
blowing machines shall be additionally equipped with
either core-box pre-heating system or gas purging and neutralization system,
or hot air purging systems.
Considering the possibility of using varied, the most advantageous
technologies of core making, the production of universal core blowing
machines equipped with replaceable devices has been undertaken in Poland. The
universal core blowing systems allow for mechanization
of core making process also with the use of sand, bonded by modern,
eco-friendly binder systems.
The paper presents selected results-based evaluation of core blowing process
showing the scope of conducted design and implementation
works.
