Welcome to inquire! Contact: Yuan Xi Chuan. Casting historic application. Ancient people used to make castings and some life appliances. In modern times, mainly used for rough casting machine parts, precision castings, and some can also be used directly as machine parts. Casting mechanical products occupy a large proportion of the streamer tank equipment, such as tractors towing tank, 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 Delta 70 to 90%. All kinds of castings, machinery used to breed up casting streamers trough shape the most complex, 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. Casting detection include visual inspection to check the size, appearance and surface chemical analysis and mechanical testing streamer tank manufacturers, the requirements of the more important problems or prone to casting the casting process, but also the need for non-destructive testing work, available Ductile Iron Castings quality testing in non-destructive testing techniques include liquid penetrant testing, magnetic particle testing, eddy current testing, radiographic testing, ultrasonic testing and vibration testing.
