Iron Casting

What is Iron Casting

Iron casting is a manufacturing process by pouring the molten material into a mold, which contains a hollow cavity of the desired shape, and then allowed to solidify.

The solidified part is also known as a casting, which is ejected or broken out of the mold to complete the process. Casting materials are usually metals or various cold setting materials that cure after mixing two or more components together; examples are epoxy, concrete, plaster and clay.

Iron casting is frequently used to make the complicated shapes

Iron Casting Material

1. Gray Cast Iron

This is the most common cast iron. They derived its name from the presence of small fractures which give the color gray in it. This is mostly used in many applications, especially for kitchen pans and other utensils.

3. Ductile Cast Iron

The other term for this is nodular cast iron. Its ductility comes from the iron alloy with high levels of carbon.

Common Used Material Standards in Iron Casting:

Cast Iron








Grey Iron



Grade 220






Grade 260






Grade 300






Grade 350




Ductile Iron



















Iron Casting Process

Resin Sand Casting

Resin sand casting process is a kind of casting process by using the resin sand as the molding material. Resin sand is a kind of mixture of quartz sand and resin. After mixing and burning, the resin sand could become very hard and solid, so we called it as the hard mold. The iron casting made by resin sand will be usually called as resin sand casting.

Resin Sand Casting advantages:

1. Dimensional accuracy, clear external outline

2. Smooth surface, good quality

3. Energy saving, labor saving.

Green Sand Casting

Green sand casting process is a kind of casting production method, which uses green sand as the molding material, the process called "green sand" casting not because the sand is green but because the sand is moistened with water and clay rather than oil. The term Green Sand means the presence of moisture in molding sand and indicates that the mold is not baked or dried. Green sand is a kind of wet quartz sand.

Except of green sand, this process need to use the cupola or medium frequency furnace. As for the molding equipment, some iron foundries use the molding machines, automatic molding lines, or just use manual molding method.

Green Sand Casting Advantages:

1. Simple production process

2. Lower production costs

3. Higher production rate
