Solution of burr and flash of die-casting aluminum alloy

Release time:

2024-02-29

Features:

Die castings have a sheet of metal on the edge of the parting surface.

Cause:

①The clamping mode is not enough; ②The injection speed is too high, and the pressure impact peak is too high; ③The sundries on the parting surface are not cleaned up; ④The mold strength is not enough to cause deformation; ⑤The insert and slider are worn and the parting is uneven.

Processing method:

① Check the clamping force and pressurization, and adjust the die casting process parameters; ② Clean the cavity and parting surface; ③ Trim the mold; ④ It is best to adopt a closed injection end time control system to realize die casting without flash.

What are the causes of direct defects in aluminum die castings?

After the completion of the production of aluminum die castings will appear some small defects such as bubbles, cracks and deformation and other phenomena, affecting our use, so what is the direct cause of these defects!

China's aluminum alloy die casting production continues to rise

In recent years, the output of aluminum alloy die castings in China has been rising, and the industry has developed rapidly, which is mainly due to the continuous casting orders in China, and the casting industry in China has also begun to be recognized and praised by foreign enterprises.

China will vigorously support the development of domestic die-casting and foundry industry

China's mechanical castings are in rapid development, with the slogan of the road of innovation advocated by our country, the continuous development of casting technology, and strive to occupy the independent research and development of technology and the right to use, in order to really lay a good foundation for the development of China's casting industry.
