How to choose the correct casting process for aluminum alloy die castings
Among hardware Die Casting Part, Aluminum Alloy Die-Casting is the most widely used and has unparalleled characteristics of other hardware die casting. Different aluminum alloys have different physical and chemical properties, and their crystallization processes are also different. According to the characteristics of different aluminum alloys, choosing a reasonable aluminum alloy casting method can better reduce defects caused by the casting process. The process performance of aluminum alloy casting can be subdivided into many types. Different aluminum alloys have different characteristics due to their different alloy compositions. The heating temperature of the alloy, the complexity of the process, artificial casting factors, etc. will also bring differences to the characteristics of aluminum alloys.
One of the main characteristics of aluminum alloy casting is gas adsorption. This is caused by the chemical reaction between the components of the aluminum alloy and the moisture contained in the combustion products, resulting in gases being absorbed by the aluminum liquid. The aluminum alloy casting process can also be divided into two categories: sand casting and metal mold casting, each with its own advantages and disadvantages. Customers can choose the aluminum alloy casting process suitable for their own production according to their own conditions.
Basic requirements for die casting part aluminum alloy die-casting parts:
1. The mold craftsmanship should be good.
2. The level of the operator.
3. Whether the performance of the die casting machine is good enough.
4. Whether the quality of raw materials passes the standard.
