Deformation Solution of Die Casting Aluminum Alloy

Release time:

2024-02-29

Features:

① Overall deformation or local deformation; ② Die casting geometry drawings do not match.

Cause:

① Poor casting structure; ② The mold is opened too early, and the rigidity of the casting is not enough. ③ The ejector rod is improperly set, and the force is uneven during ejection. ④ When the gate is located or the thickness of the gate is too thick, it is easy to deform when the gate is removed. ⑤ The resistance caused by the rough local surface of the tool is large, and the product is deformed when it is ejected.

Treatment:

① Improve the casting structure; ② Reasonably adjust the pressure holding and mold opening days ③ Reasonably set the ejection position and the number of ejector pins, preferably 4 in an open place; ④ Change the gate position so that the gate has a point and reduce the gate thickness, so that the product will not deform easily when the gate is removed, subject to ensuring the casting quality of the product; ⑤ Strengthen the mold surface treatment to reduce the demoulding resistance; ⑥ Control the temperature of the local mold to maintain the thermal balance of the mold.

"Die Casting Weekly"-On June 2, 2022, Zhejiang Tianya Jiangtao Power Co., Ltd. ("Tianya Jiangtao") and Lijin Group Ningbo Lijin Technology Co., Ltd. ("Ningbo Lijin Technology") jointly held a signing ceremony for batch purchase of large die casting units and strategic cooperation. It is reported that Tianya Jiangtao will introduce 10 sets of 1250-6000T large intelligent die casting units from Ningbo Lijin Technology. Tianya Jiangtao Chairman Hu Ronghui, Vice President Zhao Hongfu, Factory Director Peng Wenjiang, Ningbo Lijin Technology General Manager Zhang Jun, Sales Director Zhou Kang and other leaders attended the signing ceremony.

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.
