Casting Molding Process

- Sep 25, 2017 -

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, Casting Parts lighting and other industries, many are ordinary people all day contact, but do not understand the Metal objects.

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. Casting Parts 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 cars, tractors accounted for 50% to 70%; Casting Parts Agricultural machinery accounted for 40% to 70%. Liquid molding process can be so widely used because it has the following advantages: (1) can produce the 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, Casting Parts 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. Casting Parts 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, Casting Parts 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, Casting Parts 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.
