Since the ’50s of the previous century, at Sipag Bisalta we have been supplying top quality and highly reliable products to foundries. This is the result of our consolidated technical know-how underpinned by on-going innovation and the use of first-class raw materials meeting the highest European quality standards. Leading-edge equipment and technology, coupled with consolidated expertise, and the use of the best available raw materials are essential in order to guarantee excellent products. Our production fully meets these requirements, so that all our products provide high, time-enduring performance, matched with environmental compatibility, and economics. Our metal casting product range features molding sand binders, such as bentonite and blends, coal dust, molding sand additives, and briquettes.
Our technical service provides expert pre- and post-sales assistance, with the formulation, if necessary, of customized products to meet specific needs. Our Central Lab carries out full analyses of molding sands, as well as specific studies upon customer’s request.
The company is based in Genoa, Italy, with production unit in Sovizzo, near Vicenza. Somies S.r.l.
In metal casting, bentonite is used together with carbonaceous materials as an inorganic bonding material in green sand molding. For this application, we supply a full range of top quality and high performing bentonite-based products to meet our customer needs. All our products have a high montmorillonite content, offer high thermal stability, excellent bonding power, and consistent quality.
BENTONITE-COAL DUST MIXTURE AND LUSTROUS CARBON FORMERS
Coal dust employed by us is ground from suitable, constantly controlled quality sea coal, low in ash and Sulphur, and high in lustrous carbon, with a constant release of volatile matter. Since proper size distribution is key to coal dust quality, we use leading-edge equipment for its most effective grinding. Our coal dust also contains a small bentonite percentage, to ensure against spontaneous combustion. The word ‘Blend’ refers to a calibrated bentonite-coal dust mixture, where the amount of bentonite exceeds coal content.
MOULDING SAND ADDITIVES AND AUXILIARES
Molding additives are also used to lend specific features to the sand, in order to eliminate certain metal casting defects. We also produce foundry auxiliaries.
Silicon carbide and ferroalloy briquettes are employed as corrective additives in cupola furnaces. They are produced with calibrated formulations through a controlled process using the best raw materials for best title and maximum quality.
