Aluminum die casting characteristics and detection methods

Aluminum die casting characteristics and detection methods:
1,the aluminum die casting in alkaline solution, the crack was dark gray metal matrix destruction and split straight or wavy, lines narrow and long. The types of die casting products was diversified, including automobiles, motorcycles, telecommunications, home appliances, hardware, power tools, IT, lighting, escalator step, toys lights
2,aluminum die casting plant on the surface of molten metal flowing in the same direction with the stripes, there are visible and metal matrix color is not the same non-directional lines, no trends.
3,Shenzhen, aluminum die casting plant on the surface as a mesh hair raised or sunken traces, with the increase in the number and continuous casting to expand and extend.

Cause
1, the first molten metal into the cavity to form a very thin metal layer without completely after being offset by subsequent liquid metal leaving traces.
2, the mold temperature is too low
3, the inner runner cross-sectional area is too small and poorly located generate splashes.
4, acting on the lack of pressure on the liquid metal pattern: Paint excessive amount.
