China’s foundry industry has been developing steadily since the 12th Five Year Plan, but its growth rate has slowed down
The 13th five year development plan for foundry industry (hereinafter referred to as the plan) predicts that the medium and
Al-Cu system cast aluminum alloy is the earliest used casting alloy, which has high heat treatment effect and thermal stability.
1.Current situation Aluminum and magnesium are typical light metal materials. Aluminum alloy has relatively light weight, high specific tensile strength
According to the global casting production census conducted by modern casting magazine of American Foundry Association, in 2018, the global
In this design, a new aluminum silicon alloy is used as the shell casting material. By adding Al-10Sr modifier and

Casting coating is one of the indispensable raw and auxiliary materials in the casting process, which has a significant impact
For the same casting, the pouring time is different when the pouring speed is different. If the pouring speed is
Pouring temperature is the temperature at which the liquid metal enters the gate. If the pouring temperature is too high,
1 Inspection for fleshy defects of castings The contour of the two blanks is clear, and there is no obvious
The black area is the casting part, which is divided into two parts: embedded box and casting. The embedding process
EPC is divided into white area, yellow area and black area, and each part is closely linked and highly related.
Dimensional tolerance of castings refers to the difference between two allowable limit dimensions of nominal dimensions of castings. Within two
