Casting historic application. Ancient people used to make castings and some life appliances. In modern times, mainly used for casting machine parts blank cable trough, some precision castings, can also be used directly as machine parts. Casting mechanical products occupy a large proportion, such as tractors, the casting weight of about 50 to 70% by weight of the machine, agricultural machinery accounted for 40 to 70 percent, machine tools, internal combustion engines, such as the 70 to 90%. All kinds of castings, casting machinery used in the most varieties, the most complex shapes, the amount is also the largest, accounting for about 60% of total production of castings. Followed by the ingot mold and metallurgical engineering pipeline, as well as some of the tools of life. Casting is also closely related to daily life. For example, often use the door handles, locks, radiators, down the water pipes, pots, gas hob, iron, etc., are casting. Liquid metal forming processes and more cable slot manufacturers, and it is difficult to precisely control, making the casting quality is not stable enough. Compared with the forging of the same material, because the liquid forming tissue loose, coarse grains, internal easy to produce shrinkage, shrinkage, porosity and other defects. Its low mechanical properties. Another dock cable trough, labor-intensive, poor conditions. Have excellent mechanical and physical properties, it can have a variety of strength, hardness, toughness overall performance, but also combines one or more specific properties such as wear resistance, high temperature and low temperature resistance, corrosion resistance and so on. Casting weight and size range are very wide, weighs only a few grams of the lightest and heaviest cable ducts up to 400 tons, the thinnest wall thickness of only 0.5 mm, the thickness can be more than 1 meter in length by a few millimeters to ten Jimmy, can meet the requirements of different industrial sectors.
