Wytwarzanie odlewóww kokilkach wymaga niejednokronie stosowania rdzenie piaskowych. Mówi się również o rdzeniach piskowych stosowanych w odlewnictwie ciśnieniowym. Od kilku lat stosowane są masy rdzeniowe z ekologicznymi spoiwami nieorganicznymi. Masy z tymi spoiwami zapewniają komfort pracy, brak odoru i emisji szkodliwych substancji przy wykonywaniu rdzeni i zalewaniu form.

The paper presents the topics related with the production of small and medium-sized cores by means of blowing methods. The basic information concerning the manufacturers of the blowing machines and the general characteristics of machines offered by them are presented. The basic design of blowing machines are presented with discussions of the theoretical works of Boenisch, Axionov and J. Dańko determining important from the technology point of view sand and air flow parameters including different methods of core box filling factors and the factor eV representing the sand ability to evacuate from the shooting chamber.

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.
