1. Aluminum alloy gravity casting, is there any specific requirements?

Gravity casting of aluminum alloy material is called aluminum alloy gravity casting, and it has some specific requirements, so we should have a clear understanding and timely grasp. The specific requirements are: the product must have a certain strength, and good corrosion resistance. In addition, if surface treatment and heat treatment are to be carried out, then it should be able to meet the requirements and proceed smoothly in order to obtain good performance.


2. Aluminum alloy gravity casting, can it be electroplated? If the product is 1 kg, what is the weight of the gate?

Aluminum alloy gravity casting, which can be electroplated, but at this time, it should be noted that its pretreatment formula is different from ordinary aluminum alloy gravity casting. And if the product is 1 kg, then, according to the ratio of 1:1, the weight of the pouring port is also 1 kg, but it depends on the wall thickness and shape of the casting, and the need to increase the shrinkage package, etc. These aspects.


 3. What is the hot section in aluminum alloy gravity casting?

The hot section in the gravity casting of aluminum alloy, in particular, refers to the part of the casting which is later than the peripheral cooling, and if it is not noticed, the problem of shrinkage occurs at the hot section. The specific location is where the casting is thick or rounded. In addition, we also need to know that during the development of the casting process, the hot section is the basis for placing risers and cold iron.
