Die Casting Wide Adaptability Of Process Flexibility

die casting are metal forming objects obtained by various casting methods, including steel castings, cast iron parts, cast copper parts, cast aluminum parts and other types. Casting is the smelting of liquid metal, with casting, injection, inhalation or other casting methods into the prepared mold, cooling, etc., the resulting in a certain shape, size and performance of the object.

Castings have a variety of classification methods: According to the different metal materials used, it is divided into steel castings, cast iron parts, cast copper parts, cast aluminum parts, cast magnesium parts, cast zinc parts, titanium castings and so on. Each type of castings can be further divided into different types according to their chemical composition or metallographic structure. such as cast iron parts can be divided into gray iron parts, ductile iron parts, vermicular graphite cast iron parts, malleable cast iron parts, alloy castings, etc. according to the different casting molding method, the castings can be divided into ordinary sand-type castings, metal-type castings, die castings, centrifugal castings, continuous casting parts, investment castings, ceramic-type castings, Electroslag remelting castings, bimetal casting and so on. Among them, the most commonly used sand castings, about 80% of the total production. Aluminum, magnesium, zinc and other non-ferrous metal castings, mostly die castings.

Performance

The theory of casting forming metal liquid forming is often called casting, casting forming technology has a long history. As early as more than 5,000 years ago, our ancestors were able to cast copper and bronze products. Casting is the most widely used metal liquid forming process. It is the liquid metal pouring into the mold cavity, after its cooling and solidification, to obtain a certain shape of the blank or parts of the method.

In the machine equipment, the proportion of liquid forming parts is very large, in the machine tools, internal combustion engines, mining machinery, heavy machinery, liquid forming parts of the total weight of the $number; in the automobile, the tractor occupies the $number, occupies the $number in the agricultural machinery. The liquid forming process can be widely used because it has the following advantages:

(1) can produce the inner cavity, the shape very complex blank. such as a variety of box, machine bed, cylinder body, cylinder head and so on.

(2) Process flexibility, wide adaptability. The size of the liquid molded parts is almost unlimited, the weight can be from a few grams to hundreds of tons, the wall thickness can be from 0.5mm to 1m. Metals that can be dissolved into liquids in industry can be used for liquid forming. For ductile iron with poor plasticity, liquid forming is the only way to produce its blanks or parts.

(3) Low cost of liquid forming parts. Liquid molding can directly use waste parts and chips, equipment costs lower. At the same time, the liquid molding parts processing allowance is small, saves the metal.

However, the process of metal liquid forming is much, and it is difficult to control accurately, so the quality of castings is not stable enough. Compared with the forgings of the same material, due to the loose liquid forming structure and coarse grains, the internal porosity, shrinkage, porosity and other defects are easy to produce. Its mechanical properties are low. In addition, the labor intensity is big, the condition is poor. have excellent mechanical, physical properties, it can have a variety of different strength, hardness, toughness, combined with the comprehensive performance, but also a combination of a variety of special properties, such as wear-resistant, high temperature and low temperature, corrosion and so on.

Casting weight and size range are very wide, the lightest weight only a few grams, the heaviest can reach 400 tons, the wall thickness of the thinnest only 0.5 mm, the thickest can exceed 1 meters, the length can be a few millimeters to more than 10 meters, can meet the requirements of different industrial sectors.

Use

The use of castings is very extensive, has been used to hardware and the entire machinery and electronics industry, and its use is becoming increasingly expanding trend. Concrete use, construction, hardware, equipment, engineering machinery and other large machinery, machine tools, ships, aerospace, automobiles, locomotives, electronics, computers, electrical appliances, lamps and other industries, many are ordinary people contact all day, but do not know the metal objects.
