What Are the Different Types of Casting Machines?

Strictly speaking, casting machinery and equipment is a machine that uses this technology to smelt metal into a liquid that meets certain requirements and pours it into a mold. After cooling, solidification, and cleaning, a casting with a predetermined shape, size and performance is obtained. On the other hand, it is also possible to attribute casting-related machinery and equipment to casting equipment

Casting is one of the basic processes of modern machinery manufacturing industry. As a metal thermal processing technology, casting has gradually matured in China. Casting machinery and equipment are generally classified according to the molding method, and are conventionally divided into ordinary sand casting and special casting. Common sand casting includes wet sand casting, dry sand casting, and chemical hardening sand casting. According to the different modeling materials, special casting can be divided into two categories: one class uses natural mineral sand and stone as the main modeling material, such as

1.

There are mainly two types of sand casting and special casting. 1 Normal

1. Gravity casting: sand casting, hard mold casting. The molten metal is poured into the cavity by the gravity of the metal itself. 2. Pressure casting: low pressure casting, high pressure casting. Relying on the additional pressure, the molten metal is instantly pressed into the casting cavity. The casting process usually includes

With the development of science and technology and the vigorous development of the foundry industry, different casting methods have different contents of mold preparation. Taking the most widely used sand casting as an example, the preparation of the mold includes the two major tasks of preparation of modeling materials, modeling, and core making. Various raw materials used for molding and core making in sand casting, such as raw sand for casting, molding sand binder and other auxiliary materials, as well as molding sand prepared from them,

The labor conditions in the foundry industry are very harsh, and the harm to the environment is also relatively large. As a foundry company, regardless of scale, it is necessary to pay more attention to environmental protection, save energy and reduce pollution as much as possible, and lay a solid foundation for the "green" casting in the 12th Five-Year Plan. Building a resource-saving, energy-saving and environmentally-friendly foundry enterprise is a major and urgent issue facing the industry. After more than ten years of scientific experiments by industry professionals and relevant experts, continuously absorbing foreign advanced technologies and summing up their own level, the problems of substandard product quality and severe environmental pollution by the foundry industry have been basically solved. This is mainly an improvement and innovation in foundry equipment. The innovation of environmental protection casting equipment has largely promoted the development of domestic foundry industry to green casting. In the future, domestic green casting will be just around the corner. ^[2]
