Carburizing is the addition of carbon to the surface of low-carbon steels. Hardening is accomplished when the high-carbon surface layer is quenched to form marten site so that a high-carbon is superimposed on a tough, low-carbon steel core. Steels for case hardening usually have base-carbon contents. The steel, which has high carbon content, is heated in a carbon free furnace, such as air, the carbon will tend to diffuse out of the steel resulting in decarburization.

Carcass Washers are designed to remove foreign matter from the feathers prior to the scalder. This provides cleaner scalder water by reducing the amount of solids and pathogen load.

Card Cages are metal frames that support and contain electronic components and power supplies. They include a backplane with slots for installing expansion boards, a power supply, cooling fans and connectors. It supports active and passive backplanes of a specific bus type. It includes multi-system extension interface (MXI), embedded technology extended (ETX), embedded PCI extended (ePCI-X), advanced telecommunication computing architecture (AdvancedTCA) and host media processing (HMP).
