Nodular cast iron


Nodular cast iron is a high-strength cast iron material developed in the 1950s. Its comprehensive properties are close to steel. It is based on its excellent properties that it has been successfully used to cast some complex components which ask for high forces, strength, toughness, and wear resistance.
Nodular cast iron is obtained by spheroidization and inoculation treatment to obtain nodular graphite, which effectively improves the mechanical properties of cast iron, especially the plasticity and toughness, thereby obtaining higher strength than carbon steel.

 

Green Sand Molding Process

 

Green sand molding is by far the most diversified molding method used in the current casting processes. The process uses a mould made of compacted moist sand. The term “green” denotes the presence of moisture in the molding sand and indicates that the mold is not dried. The mold material consists of silica sand mixed with a suitable bonding agent “clay” and moisture.

To produce the mold, usually a metal frame, although wood may be used for some processes and types of castings, is placed over the pattern to produce a cavity representing one half or one part of the casting. Compaction is achieved by either jolting or squeezing the mold. The other half of the mold is produced in a like manner and then the two halves or three parts are positioned together to form the mold.

If the casting has hollow sections, a core consisting of hardened sand (baked or chemically hardened) is used. Cores are located in pockets formed by projections on the pattern equipment to produce core prints. Should extra support for the cores be required, chaplets or spacers are properly positioned to maintain the required dimension. These will fuse with the molten metal when the casting is poured. This type of molding is the best known of all the sand casting molding methods, as the molds may be poured without further conditioning. This type of molding is also most adaptable to light, bench molding for medium sized castings or for use with production molding machines.
