Foundry

Eirich specializes in systems for preparing bentonite-bonded molding sand. An increasing number of Eirich sand mixer systems for gray iron, steel, and non-iron castings are supplying the molding lines of major manufacturers worldwide, delivering quality, throughput, and efficiency. High-quality metal castings are imperative for many different industries. Foundries making sand castings want to avoid process variations and rejects/scrap due to low quality sand and therefore subpar molds. 

Benefits of Eirich’s innovative molding sand solutions:

The high-energy mixing tool allows for fast and even distribution of sand, added water, and bentonite. The rotating pan and wall-bottom scraper contribute to no dead zones and every grain of sand being transported through the pan. This results in optimal homogenization. 

The bentonite is completely activated and forms a uniform coating on the grains of sand. 

The results: top molding material quality, reproducibility, and less rejects/scrap. 

Eirich mixer sizes for foundries range from 75 liters up to 7,000-liter capacity.  Our foundry equipment includes sand testing with control software and correction, moisture analyzer with control software and correction, sand cooling with air and sand cooling under vacuum (EvacTherm®)
