Casting historic application. Ancient people used to make castings and some life appliances. In modern times, mainly used for casting blank ports three slot machine parts cable ducts, 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, castings up to a maximum variety of machinery, shape the most complex three-slot dock cable trough price, the amount is also the largest, accounting for about 60% of the 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. 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 also very fast three-slot dock cable ducts supply, especially in the late 19th century and the first half of the 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 Leaf has been improved and practical.
