ALFE BRNO, Ltd.,a foundry founded in 1912

Manufacture of precision zinc castings

Besides the classic foundry production we are ensuring the manufacture of precision castings from zinc by a modern technology of centrifugal casting in rubber moulds. Centrifugal casting offers higher quality in the field of material strengths, casting accuracy and better reproduction of details. It gives high quality parts from common commercial zinc alloys.

Centrifugal casting offers an alternative solution to the die casting technology. In case of required amount of castings from 200 pieces up to several thousands’ series this technology is economically more advantageous. Besides high financial savings in manufacture of moulds this process is more economical as it is more time- and labour-saving one. After supplying the patterns the mould can be manufactured in several hours and castings can be made in several days.
