Solution to surface strain of aluminum alloy die casting

Release time:

2024-02-29

Cause:

① The surface of the mold cavity is damaged; ② The direction of the mold is not inclined or the inclination is too small; ③ The ejection is unbalanced; ④ The mold is loose; ⑤ The casting temperature is too high or too low, and the mold temperature is too high to cause the alloy liquid to adhere; ⑥ The effect of the release agent is not good;

⑦ The iron content of aluminum alloy composition is less than 0.8%;⑧ The cooling time is too long or too short.

Processing method:

① Repair the surface damage of the mold; ② Correct the slope to improve the surface finish of the mold; ③ Adjust the ejector rod to balance the ejector force; ④ Tighten the mold; ⑤ Control the reasonable casting temperature and mold temperature of 180-250;⑥ Replace the mold release agent: ⑦ Adjust the iron content of aluminum alloy; ⑧ Adjust the cooling time; ⑨ Modify the internal gate and change the direction of aluminum liquid.

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.
