Casting weight and size range are very wide dock streamer tank equipment, only a few grams of the lightest and heaviest 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 mm 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 efficiency of the hydraulic system, the development of energy consumption and cavitation etc; intensity combustion engine block, cylinder head, cylinder, piston rings, exhaust pipes and other castings and resistance to spalling resistance, direct impact on the working life of the engine.

Casting historic application. Ancient people used to make castings and some life appliances. In modern times, mainly used for rough casting streamers dock slot machine parts, precision castings, and some can also be used directly as machine parts. Casting mechanical products occupy a large proportion, such as tractors, casting about 50 to 70% by weight of the whole weight of the towing tank ports, agricultural machinery accounted for 40 to 70 percent, machine tools, internal combustion engines, etc. up to 70 ~ 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.
