What Is Freeze Casting?

Freeze casting method: Freezing refers to the process of smelting metal into a liquid that meets certain requirements and pouring it into a mold. After cooling, solidification, and finishing, a casting with a predetermined shape, size, and performance is obtained.

Casting is the process of smelting a metal into a liquid that meets certain requirements and pouring it into a mold. After cooling and solidifying and finishing, a casting with a predetermined shape, size and performance is obtained. Because the casting blank is almost formed, the purpose of avoiding machining or small amount of machining reduces the cost and time to a certain extent. Casting is one of the basic processes of modern machinery manufacturing industry.

There are many types of casting, which are customarily divided into: ordinary sand casting, including wet sand, dry sand and chemically hardened sand. Special casting, according to the molding materials, can be divided into special castings with natural mineral sand and gravel as the main molding materials (such as investment casting, mud casting, shell casting in foundry, negative pressure casting, solid casting, ceramic casting) Etc.) and special castings (such as metal casting, pressure casting, continuous casting, low pressure casting, centrifugal casting, etc.) with metal as the main mold material. The casting process usually includes: Preparation of casting molds (making liquid metal into solid castings). The casting molds can be divided into sand, metal, ceramic, clay, graphite, etc. according to the materials used. For casting, semi-permanent and permanent, the quality of casting preparation is the main factor affecting the quality of castings; melting and casting of casting metals, casting metals (casting alloys) mainly include cast iron, cast steel and nonferrous alloys; castings Treatment and inspection, casting treatment includes removal of foreign bodies on the core and casting surface, removal of sprues, burrs and burrs, etc., as well as heat treatment, shaping, rust prevention and rough processing.
The casting process can be divided into three basic parts, namely the preparation of the cast metal, the preparation of the mold and the processing of the casting. Casting metal refers to the metal material used for casting in casting production. It is an alloy composed of one metal element as the main component and the addition of other metal or non-metal elements. It is customarily called a casting alloy. Cast steel and non-ferrous alloys.
