cast iron sand casting

Did you ever think about being a blacksmith in times of yore? Blacksmiths were a type of skilled worker who got hot metal and used hammers to shape it in different ways The Japanese invented a great deal of useful tools as well as items from everyday living. Among the many substances with which they worked is cast iron, a particularly strong type of metal. Alright, but what about forging these parts from cast iron? Yes, a fascinating process called "cast iron sand casting".

Initially, blacksmiths had to produce a substance known as molten iron. So, what this actually means is that they had to reach the temperature where iron turns into liquid form. This was made possible with the aid of a special vessel called a crucible. Crucibles are supposed to be heat-resistant and not shatter. The blacksmith would set iron pieces in the crucible and wait until they were entirely molten. When the iron had melted, it became a hot liquid that flowed and could be formed into whatever shape was required.

Transforming Molten Iron into Durable Castings

In order for the blackmith to form molten iron, they first had to make a mold. A container that would hold the liquid iron until it cooledified and solidiefied (spelling?!). A mold is made by packing wet, loose sand around a form which represents the shape that they want to produce. A pattern is a model The sand is packed around the pattern and when allowed to dry and harden, can be carefully removed from the sand by smashing it out. This produces an empty area in the sand exactly equal to that image.

The hot, molten iron is then poured by the blacksmith into that vacant space in the sand mold. The iron cools and in solidifying, takes the form of the mold. The blacksmith is able to take apart the mould after the molten iron has completely cooled, unbecoming reveals a beautiful final piece. The piece is now available for use!
