Zinc Die Casting Defects
Die casting can be simply defined as a metal casting process in which the molten metal is poured into a cast to produce a finished product with desired specifications and superior quality. Die casting is considered as one of the most effective and best metal shaping processes for creating components with excellent properties. In fact, a number of die casting companies from all over the globe implement the use of this metal shaping process to produce automobile, electronic, and mechanical products.
One of the most common alloys used in die casting is zinc. Zinc is one of the most preferred choices of several die casting companies due to the number of benefits this alloy offers. For instance, zinc alloys are highly ductile and they are also capable of withstanding wear and tear for a greater period of time. These two excellent attributes of zinc alloys make them an ideal choice for die casting applications.
However, it is significant to note that some defects may accidentally happen during die casting. Some of these defects may cause slight or severe damage to the finished product while other might not even have an effect on the manufactured product. Below are some of the most common defects that may happen during zinc die casting.
Shot Over
If zinc alloys from any of the previous mold are still present in the mold during the pouring of the next batch, then there is a chance for a shot over to occur. When this happens, you will be able to see that a piece of the zinc alloy is attached to the next mold. The good news is that this defect will not affect the finished product’s strength.
Crack
If the temperature during the die casting process falls below or above the normal casting temperature, then cracks may develop on the surface of the finished product. If the cracks on the surface of the product are bigger, they may force the finished product to break.
Shrink
This is one of the most common defects that happens during zinc alloy die casting. If the die casting alloy is subjected to cooling after the completion of the die casting process, then there is a good chance for this defect to happen. However, seeking the help of an expert die casting company will enable you to stay away from these kinds of die casting defects.
