The pressure may be obtained by compressed air or by hydraulically operated plunger. A counter-gravity casting equipment (CGCE) has been developed, which is specially designed for the production of large-size thin-walled high-quality aluminum alloy parts with resin sand molds. These ferroalloy and casting standards are helpful in guiding metallurgical laboratories and refineries, product manufacturers, and other end-users of cast iron and its alloys in their proper processing and application procedures to ensure their quality towards safe use. Established in 1998, The Group has its headquarters and production plants in Padua.
