Aluminum casting pinhole formation causes

In the aluminum alloy casting production process, molten aluminum pouring environment temperature is generally 610 ~ 660 ℃. Under such conditions, many vapors (usually radon gas) melted in lithium bromide solution. Aluminum alloy profile hydrogen solubility and aluminum alloy material environment temperature is closely related. 660 ℃ about liquid aluminum liquid is about 0.69cm3/100g, 660 ℃ about solid aluminum alloy profile is only 0.036cm3/100g. Therefore, when the aluminum alloy profile condensation, aluminum alloy casting is a lot of hydrogen deposition of the way of the vapour bubble.

Let me tell you aluminum alloy die casting process and die casting mold optimization analysis

Die casting process is refers to the use of high pressure effect, the metal liquid quickly added to the die casting mold cavity, the metal liquid cooling condensation casting parts produced after the process way. The die-casting process mainly includes two basic methods: cold chamber die-casting and hot chamber die-casting. In the contemporary industrialized production, die casting process is mainly used for manufacturing all kinds of metal parts, the application of die casting process production process is very little or no need to carry out metal cutting, production and manufacturing work efficiency is high, with significant economic benefits.

Aluminum die casting surface mold how to deal with

As we all know, in the die-casting aluminum alloy field aluminum alloy die casting air oxidation problem, alias "long mold", "long mold", "moldy powder", "surface mold". Will not only lead to a lot of waste material to enhance the cost of fees, and also due to delayed supply or customers at the occurrence of mold new products lead to the return of goods and many other problems, so aluminum alloy die casting air oxidation problem can not be ignored.
