One Minute Takes You Through The Forming Process Used in Foundries

What is the molding process for foundry casting? Let's take a look together. 1. Gravity casting: sand casting, hard mold casting. Relying on the gravity of the metal itself, the molten metal is poured into the hollow. 2. Pressure casting: low pressure casting, high pressure casting. The foundry relies on the extra pressure to instantly push molten metal into the casting cavity.

What aspects of the foundry casting process typically include? Let's take a look together. Casting mold preparation, casting mold according to the material used can be divided into metal type, ceramic type, clay type, graphite type, etc., according to the number of use can be divided into one-time type, the casting mold preparation of the foundry is the main factor affecting the quality of castings. Melting and casting of cast metals, casting metals mainly include various cast iron, cast steel, cast non-ferrous metals and alloys.

Casting treatment and inspection in foundries, casting treatment includes removing foreign matter on the core and casting surface, removing main channels, wear, protrusions such as capes, heat treatment, molding, anti-rust treatment, rough machining, etc. The foundry casting process can be divided into three basic parts: casting metal preparation, mold preparation, and casting processing. The casting metal of the foundry is a metal material used for casting castings in casting production, with a metal element as the main component, plus other metal or non-metallic elements made of alloy, customarily called casting alloy, mainly cast iron, cast steel and cast non-ferrous alloy.

Metal smelting in foundries is not just simple melting, but also includes the smelting process to bring the metal poured onto the mold to the desired temperature, chemical composition, and purity. To this end, various testing tests for the purpose of quality control are carried out in the smelting process, and liquid metals can be allowed to be injected after reaching various specified indicators. Sometimes, in order to meet higher requirements, the molten metal in the foundry is also processed outside the furnace after baking, such as desulfurization, vacuum degassing, out-of-furnace refining, incubation or deterioration. Commonly used equipment for smelting metals include cupola, electric arc furnace, induction furnace, resistance furnace, reflex furnace, etc.

The foundry will introduce the advantages for you: 1. It can produce parts with complex shapes, especially blanks with complex inner cavities. 2. Wide adaptability, commonly used metal materials in industry can be cast, ranging from a few grams to hundreds of tons. 3. Raw materials come from a wide range of sources and low prices, such as chips, waste, chips, etc. 4. The shape and size of the casting of the foundry are very close to the parts, reducing the amount of cutting, which belongs to no cutting processing. 5. Wide application, 40%~70% in agricultural machinery, 70%~80% of the weight in machine tools are castings.
