The lost foam casting process offers several advantages over conventional sand casting processes, such as simplified production techniques and reduced environmental waste due to binder system emissions and sand disposal.

Electroplating is a process that uses an electric current to reduce dissolved metal cations so that they form a thin coherent metal coating on an electrodethe term is also used for electrical oxidation of anions on to a solid substrate, as in the formation of silver chloride on silver wire to make silver/silver-chloride electrodes. Simulation software is a valuable tool that helps designers and engineers understand the details of the casting process, enabling them to consistently create high-quality parts faster and with lower costs than their competitors. The lost foam process is accepted as the process of choice for high-volume complex components such as blocks and heads the automotive and marine compressors for heating and air conditioning industry electric motor housings counterweights for heavy equipment hydraulic valves, hydrants, pipe and fittings for water distribution industry heat exchangers for various industries.
