High quality Full painting cast alloy car wheel, 15×6.5J 4holes 4X100 ET35 alloy car rim

Aluminum alloy wheels have two production processes-casting and forging. Compared with casting, the former of the Golden Phase is crushed grain and forging tissue, and the latter is a chipocarne -like grain and cast state tissue. In terms of single mechanical performance indicators, forging parts are generally 20%to 30%high, and individual indicators are higher. In the international market, the price of forging wheels is twice as high as cast. Domestic aluminum alloy wheel manufacturing mainly adopts a low -pressure low -voltage casting process, accounting for more than 80%of the total output; followed by a simpler gravity casting process, less than 20%of its total output; and the use of extrusion casting process. , Its product quality has improved, but the proportion is small.
At present, nearly a hundred companies in China have used low -pressure casting processes to produce cars and motorcycle aluminum alloy wheels 1. The advantages of the low -voltage casting process are manifested in the following aspects: ① The liquid metal charging is relatively stable: ② the casting of the casting is good, which is conducive to forming a clear contour and a smooth surface. Crystal under pressure, dense tissue of castings, and good mechanical properties; ④ Because there is no need to take a surgery, the utilization of metal liquid is greatly improved, generally 90%; ⑤ good labor conditions, easy to achieve mechanization and automation.
Low -voltage cast aluminum alloy wheels find that the SI bias is found during material testing, which will affect the use of aluminum alloy wheels in severe cases. Under the premise that the customer’s material and safety performance of the car aluminum alloy wheels are constantly high, the SI bias analysis of the aluminum alloy wheels is controlled to meet the needs of the customer.
