Die Casting Use Very Widely

Castings are made of various casting methods of metal forming objects, including cast steel, cast iron, cast copper, cast aluminum and other types. Castings are smelted with good liquid metal, with casting, injection, suction or other casting method into the prepared mold, after cooling, etc., the resulting shape, size and performance of the object.

Casting applications have a long history. Ancient people with castings and some life appliances. In modern times, castings are mainly used as blanks for machine parts, some precision castings, and can also be used directly as part of a machine. Casting in the mechanical products occupy a large proportion, such as tractors, the casting weight of about 50 ~ 70% of the weight of machinery, agricultural machinery accounted for 40 ~ 70%, machine tools, internal combustion engines in 70 ~ 90%. All kinds of castings, the largest use of mechanical casting varieties, the most complex shape, the largest amount, accounting for about 60% of the total output of castings. Followed by metallurgical ingot molds and engineering pipes, as well as some of the tools in life. Casting is also closely related to daily life. For example, often use the door handle, door locks, radiators, water pipes, wok, gas stove, iron, etc., are cast.

Casting forming the theory of metal liquid molding is often called casting, casting forming technology has a long history. As early as 5000 years ago, our ancestors will be able to cast red copper and bronze products. Casting is the most widely used metal liquid forming process. It is the liquid metal pouring into the mold cavity, to be cooled after solidification, access to a certain shape of the blank or parts of the method.

In the machine equipment, the proportion of liquid molding is very large, in the machine, internal combustion engine, mining machinery, heavy machinery in the liquid molding parts of the total weight of 70% to 90%; in the car, tractors accounted for 50% to 70%; Agricultural machinery accounted for 40% to 70%. Liquid molding process can be so widely used because it has the following advantages:

(1) can create a cavity, the shape is very complex blank. Such as a variety of boxes, machine bed, cylinder block, cylinder head and so on.

(2) process flexibility, wide adaptability. The size of the liquid molding is almost unlimited, its weight can be from a few grams to several hundred tons, the wall thickness can be from 0.5mm to 1m or so. Industry can be dissolved into liquid metal materials can be used for liquid molding. For poorly castable cast iron, liquid molding is the only way to produce its blanks or parts.

(3) the cost of liquid molding is low. Liquid molding can be directly used waste parts and chips, equipment, low cost. At the same time, liquid molding parts processing margin is small, saving metal.

However, the metal liquid forming process and more difficult to precisely control, making the casting quality is not stable enough. Compared with the same material forging, due to liquid forming tissue loose, coarse grain, the internal easy to produce shrinkage, shrinkage, porosity and other defects. Its mechanical properties are low. In addition, labor intensity, poor conditions. Has excellent mechanical and physical properties, it can have a variety of different strength, hardness, toughness with the comprehensive performance, but also both one or more special properties, such as wear, high temperature and low temperature, corrosion resistance.

Casting the weight and size range is very wide, the lightest weight of only a few grams, the most important can reach 400 tons, the wall thickness of the thinnest only 0.5 mm, the thickest can be more than 1 meter, the length can be from a few millimeters to ten meters, To meet the requirements of different industrial sectors.

use

Casting is widely used, has been applied to the hardware and the entire machinery and electronics industry, and its use is to continue to expand the trend. The use of large-scale machinery, machine tools, ships, aerospace, automotive, motorcycle, electronics, computers, electrical appliances, lighting and other industries, many are ordinary people all day contact, but do not understand the Metal objects.
