With the advance of science and technology and the foundry industry's vigorous development, different casting methods have different casting preparation content. The most widely used sand casting, for example, casting preparation, including modeling material preparation and modeling, core-making two major operations. Sand casting used to modeling, core-making a variety of raw materials, such as casting sand, sand binder and other auxiliary materials, as well as formulated by them into the sand, core sand, paint, etc. collectively referred to as modeling materials, modeling materials to prepare for the mission is in accordance with the requirements of the casting, the nature of the metal, selecting the appropriate raw sand, binder and auxiliary materials, and then according to a certain proportion of the mixture into the sand with a certain function of the sand and core sand. Commonly used sand mixing equipment are wheel mixer, counter-current sand mixer and continuous sand mixer. The latter is designed for mixing chemical self-hardening sand, continuous mixing, sand mixing speed.

Manufacture and application of ferrous castings
Ferrous castings are a common manufacturing material with a wide range of applications. Its manufacturing process includes mold making, melting, casting and cooling. First of all, the manufacture of ferrous metal castings requires the production of corresponding molds according to the design requirements to ensure the accuracy of product size and shape. Next, the metal raw materials are melted at high temperatures, the metal liquid is poured into the mold, and after cooling and solidification, the casting with the required shape and structure is obtained.
