At normal temperature and humidity, the casting sand mixing ratio suitable for automated molding lines is: mixing ratio (weight ratio) casting old sand 95%, new sand 3%, bentonite 0.8-1.0%, coal powder 0.4-0.5%, water accounts for 3% of the total weight of all materials (not exceeding 3%);

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);

We can customize a molding machine with suitable sand box size and height according to the user's casting design requirements. The appearance color can be selected and matched according to the culture of different regions and user needs

After starting the molding machine, run the hydraulic device first. The equipment can only be operated normally after the hydraulic device reaches the normal oil temperature; 2. Regularly check the lubrication pump of the molding machine. When the oil level in the lubrication pump's oil tank is insufficient, lubricating oil should be added in a timely manner;

The green sand automated foundry mainly consists of melting equipment, sand mixing equipment, molding equipment, pouring equipment, cleaning equipment, testing equipment, processing equipment, etc;

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.

When the moisture content in the casting sand increases by 1%, the permeability of the sand will decrease by about 15%. Once the permeability decreases, if the gas generated inside the mold cavity during casting cannot be discharged in a timely manner, the surface of the casting is prone to defects such as porosity, which seriously affects the quality of the casting;

The development of enterprises cannot be separated from the development of automation and mechanization, which is also a stage that enterprises need to go through; The following will introduce the advantages of casting enterprises using automated casting equipment in production compared to traditional manual casting:
