Casting weight and size range are very wide, weighs only a few grams of the lightest dock cable roller, the heaviest up to 400 tons, the thinnest wall thickness of only 0.5 mm, the thickness can be more than 1 meter cable roll price, length can be a few millimeters to ten meters, can meet the requirements of different industrial sectors. Casting quality has a great impact on the performance of mechanical products. For example, wear resistance and dimensional stability of the casting machine, a direct impact on the accuracy of the machine to maintain life; all kinds of pump impeller, housing and hydraulic cavity size, accuracy and surface roughness profile, directly affect the pump and hydraulic system efficiency roll supply cable, power consumption and cavitation development etc; the strength of the internal combustion engine block, cylinder head, cylinder, piston rings, exhaust pipes and other castings and resistance to spalling resistance, direct impact on the engine working life. Casting is an ancient method of manufacturing in the country can be traced back to 6,000 years ago. With the development of industrial technology, quality casting large castings directly affects the quality of the product, therefore, plays an important role in casting machinery manufacturing industry. Casting technology development is very fast, especially on the late 19th and 20th century, there have been many new casting methods, such as low-pressure casting, ceramic casting, continuous casting, etc., in the second half of the 20th century, has been improved and practical .
