Green sand casting medium-sized sand is reusable and recyclable; It is mainly composed of old sand, and new sand (quartz sand, silica sand), bentonite, coal powder, water and other auxiliary materials are added during the mixing process. After stirring evenly, casting sand that meets the forming and pouring conditions is obtained;

In the process of transitioning from traditional casting enterprises to mechanized and automated casting workshops, it is very important to have a reasonable layout and planning of the workshop site; Mainly including: area allocation of casting workshop, layout of casting equipment, environmental requirements, and protective measures to be taken (safety protection);

The main function of the clay sand processing line is to recycle and reuse the old sand from the molding line. After being processed through steps such as sand falling, crushing, and screening, it is mixed with new sand to provide sand for the molding line molding host again. In normal operation and production, the fully automatic horizontal molding line can be equipped with a clay sand processing production line with a processing capacity of 20T per hour for single machine sand boxes within the range of 420mm-610mm.

With the development of machinery and automation technology, many casting enterprises are also following the pace of technological development to achieve automation and mechanization in casting; And China's casting industry also achieved rapid development after the Chinese government fully implemented the "Blue Sky Protection Plan" in 2018; The development of any macro level casting enterprise cannot be separated from the development of automation and mechanization, which is also a stage that enterprises need to go through for development;

After completing the molding of the sand mold through an automated casting molding machine, timely emission of gas from the internal cavity of the sand mold is also crucial when pouring metal liquid into the sand mold; Under the thermal action of liquid metal, a large amount of gas is generated inside the sand mold. If the sand mold does not have good exhaust capacity, various unexpected situations are prone to occur during the pouring process, such as cracking of the sand mold, gas promoting the reflux of the metal liquid, inability of the metal liquid to fully fill the mold cavity, and the production of pores in the casting;

Using tidal sand as a casting material to produce castings is a relatively traditional and widely used casting process, suitable for casting iron based castings, and also commonly used in the production of copper based castings. The difference between this casting process and other casting processes is that most of the old sand can be recycled through appropriate treatment processes after tidal sand casting. Therefore, the tidal sand casting process has the greatest advantage in terms of casting material cost compared to tidal sand casting process.

The mold of the fully automatic horizontal parting casting molding machine is a double-sided mold, usually made of lighter aluminum molds, and steel molds are also used; The fundamental difference between the traditional semi-automatic molding machine and the fully automatic horizontal parting casting molding machine lies in the fact that the automatic molding machine uses hydraulic cylinders to compress the sand inside the sand box in one go and with high strength, which has certain requirements for the hardness and strength of the mold to avoid damage to the mold when the compaction pressure increases during the sand mold compaction process;
