The chuck is a special metal form, it can be either one-piece or collapsible, depending on the complexity of the part being made. This method makes it possible to create a casting with excellent mechanical properties with high precision and fast manufacturing speed. In addition, the chill mold can also be used repeatedly. Before pouring molten metal into the chill mold, the mold is heated to a temperature of about 300 degrees Celsius and fire-resistant paint is applied to its inner walls. With the help of special rods, installed after processing with paint, both halves of the chill mold are securely and with maximum accuracy, fastened together. The melt is also prepared before casting. In the distributing furnace, it undergoes a special metallurgical treatment, which is: degassing - removal of harmful toxic substances, gases; modification - improving the properties of a substance by mixing it with other substances; and settling — removal of insoluble oxides from the melt. Then the melt with a volume of one part is poured into a special ladle, from which it is poured directly into the gating system of the casting mold. Due to its liquid state, the melt completely occupies the mold, filling each of its contours, until it reaches the top of the mold, which is called a profitable extension. Before removing the casting from the chill mold, remove the metal rods. Then, the casting itself is removed with pushers. If necessary, the resulting product is subjected to cleaning and heat treatment, and the obligatory cutting of the profitable extension. In order to avoid frequent thermal burns by workers, at most enterprises, the technology of casting aluminum into a chill mold is automated. A person only drives a car at a distance safe for his health. Over the method of casting parts under pressure, casting in a chill mold has many advantages, among them the fine-grained structure of the resulting casting, which contributes to an increase in the strength and ductility of the metal. Due to the strong fastening of the chill mold, errors in the shape of the product practically disappear. However, this method, like any other, has disadvantages, such as the increased cost of creation due to the profitable extension, as well as the possible appearance of warpage, internal stress, cracks, due to the intense prevention of shrinkage of the casting.
