The Defects Of Die Casting
In fact, each metal die casting process has its unique advantages and disadvantages that we’ve discussed in the previous chapters.
Below is a summary of the defects of die casting process:
HIGH INITIAL COST
Setting up the metal die casting plant can be an expensive process.
This is the main reason why it is highly recommended for the metal die casting companies to conduct a comprehensive feasibility study.
It is through this that they can tell whether the process is feasible or not. The cost of the dies, machines and other equipment is somehow high.
LIMITED TO HIGH PRODUCTION
This process is only economical for large production. The small scale production makes the process very expensive.
This explains the reason why most companies avoid small quantity production.
THE PROCESS IS LIMITED TO FLUIDITY METALS
This refers to those metal alloys that can flow.
It will be nearly impossible to force a metal that can’t flow through the die.
Therefore, it is important to evaluate all factors that can affect the fluidity of the metals.
The company should have a lab to test each metal to ensure that they meet the desired die casting criteria.
LIMITATION OF THE TYPE OF METALS TO DIE CAST
Not all metal alloys can be die cast. In most cases, the process is suitable for non-ferrous alloys.
Apart from this, it is also worth noting that the process may not be suitable for heavy casting.
This is the main reason why companies opt for the sand casting processes.
Thus, you need to be sure of the exact specifications of the metal to die cast.
Again, you need to take special considerations when removing the cast part from the die. This is to avoid porosity problems.
From the above, it is quite evident that the advantages of die casting process are actually more than the disadvantages.
This further confirms the reason why it has been adopted for a number of manufacturing processes.
You need to have effective measures that will eliminate any circumstance that may compromise the quality of the final die casting component.
