     Coated sand is a high-quality sand with many advantages. The mold is specially used for casting workpieces of various shapes. A manufacturing method of precision casting, coated sand has the advantages of high energy resistance, easy molding, low cost, so it is widely used.

In the streets, all kinds of cars, form a hundred. So these cars are specially molded? Mold! Yes, 90% of the above parts processed by our molds on the car are manufactured by molds. Then you can imagine what kind of society a modern society would be without cars; what kind of world would it be without molds; what kind of product would it be without a coated sand mold.

Coated sand molds can be used to process high-precision parts such as auto parts, aerospace parts, and mobile phone parts. It can be seen that the coated sand is widely used in the outside life. Without it, our car would not be black and smoky, noisy, severely underpowered, and ugly in appearance. Without coated sand mold, can the plane soar in the lifeless days? Is the place passing by "dark clouds"? Without coated sand, is the mobile phone very heavy, bulky, rough surface and intermittent signal?

Coated sand mold, a "tip" in life, although many people do not know his existence, but the products cast in our hands, feet, etc., have been integrated into every corner of life.

Production of coated sand recovery equipment should pay attention to the following matters:

1. Regularly carry out dust removal and dust prevention work, check whether the dust collector is operating normally, and replace the dust bag that is damaged or used for too long. Prevent excessive dust from affecting the performance of the coated sand.

2. Improve the utilization rate of old sand. The regeneration of the old coated sand reflects the operation and circulation of resources, reduces the casting waste, makes the old sand become the raw material, realizes the circulation operation, reduces the pollution of the old sand to the environment, and saves the raw material. Improve the bonding strength and reduce the amount of phenolic resin.

3. Pay attention to the ambient temperature: the silicon oxygen bond activity of the reclaimed sand is enhanced, which increases the coverage of the phenolic resin, thereby increasing the combination of sand and resin to prevent slag inclusion in the casting. Adjusting the ambient temperature can increase productivity, reduce sand mold damage and casting defects, reduce resin addition, save costs, and reduce environmental pollution.

To sum up, the electrical equipment automatic control system of the coated sand production line is determined according to the production and manufacturing outline, the level of automation machinery and the total investment, the level of automation technology and the total investment, and the resin sand production line with efficient automation technology is equipped with an intermediate main control room to monitor the modeling design, sand vacuum equipment, etc.
