At Królmet Iron Foundry some research and experimental studies have been carried out to develop technical and technological guidelines for the manufacture of pilot castings for machinery applications. The castings should be characterised by good mechanical properties, specially by good hardnesss, high abrasion wear resistance and impact resistance. Pilot castings have been made by lost foam technology on a modern casting installation. The output of the research and experimental work was designing and making of pattern tooling, determination of technical and technological parameters of the process, and making a batch of pilot castings. The produced castings had the required utilisation parameters.
