Different kinds of molding sand are green sand, dry sand, facing sand, core sand, loam sand, parting sand, backing and floor sand, system sand, and molasses sand. 1. Green Sand: These …
Almost every manufacturing industries uses moulding sand to make moulds. Casting of materials without use of moulding sand is impossible. Here we are going to discuss about different types of moulding sand.

From grain size distribution to permeability, refractoriness, and cohesiveness, each property influences the behaviour of the sand during mould preparation, metal pouring, and solidification.
Moulding sand is classified into different categories according to the nature of its origin. The principal constituents of moulding sands are as follows: i. Silica (SiO 2)—86 to 90%, ii. Alumina (Al 2 O 3)—4 to 8%, iii. Iron oxide (Fe 2 O 3)—2 to 5% with smaller amounts of the oxides of Ti, iv. Mn. v. Ca, and some alkaline compounds. Natural Sand:
Different kinds of molding sand are green sand, dry sand, facing sand, core sand, loam sand, parting sand, backing and floor sand, system sand, and molasses sand. 1. Green Sand: These types of molding sand are natural sand with enough moisture in them.
In this article, we shall explore the types of molding sand and their properties. We have provided a PDF download for the same. Molding sands are usually compressed or heated as well as moistened by engineers to induce a specific shape. The sand is also termed Foundry Sand as it is used in the casting process.

Following are the 8 different types of moulding sands: 1. Green Sand. Green sand is a sand or sandstone which has a greenish colour. it is a mixture of silica sand with 18 to 30% clay, having total water of 6 to 8%. It is soft, light and porous with clay and water furnishing the bond for green sand.
Moulding sand essentially contains the following three constituents. 1. Refractory sand. 2. Binder. 3. Additive. These types of sand are used in moulding for the following reasons. 1. It maintains …

According to the use, moulding sand may be classified as below: 1. Green Sand: The green sand is the natural sand containing sufficient moisture in it. It is mixture of silica and 15 to 30% clay with about 8% water. Clay and water act as a bonding material to give strength. Molds made from this sand are known as green sand mould.
Moulding sand essentially contains the following three constituents. 1. Refractory sand. 2. Binder. 3. Additive. These types of sand are used in moulding for the following reasons. 1. It maintains shape at very high temperature. 2. It makes a mould porous. 3. It can be used again and again. 4. It is inexpensive. 1. Constituents of Moulding Sand.
