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;

The common automated casting and molding production lines for tidal sand (clay sand) mainly include vertical parting box less injection molding line, horizontal parting box less injection molding line, and multi contact static pressure box molding line. In the past decade of rapid development and widespread application, machine automatic molding technology, automated pouring, and automated sand mixing and sand making technology have become very mature. Currently, most casting molding lines work on the principle of using pneumatic sand addition and hydraulic compaction to achieve automatic molding of sand molds.

The chemical composition of ductile iron castings must be strictly controlled, otherwise it is difficult to meet customer requirements. Strictly control the process from the selection of raw materials, formulation of smelting process, temperature control, and pre furnace spheroidization incubation treatment. Below, we will summarize and introduce the key points of ductile iron smelting and spheroidization treatment!

The frame sleeve of the horizontal parting automatic casting molding machine is widely used in sand mold casting production. The main material used is aluminum or ductile iron (QT) material, which is cast and formed. The inside of the frame sleeve is finely processed into serrated and inclined concave and convex patterns using a milling cutter, ensuring that the sleeve box and sand mold can be accurately and tightly fitted, and also facilitating the heat dissipation and exhaust of the sand mold inside the cavity during the pouring process.
