Die casting process is widely used in the manufacturing sector and automobile industries because of many advantages of the die casting process. Let us have a deep insight into the pros and cons of die casting.
Advantages of die casting :
- Because of the use of movable cores, it is possible to obtain complex casting than that by permanent mould casting.
- Production rate is very high. The typical rate could be 200 pieces per hour.
- Die casting process is completely automated.
- Very small thickness can be easily filled because the liquid metal is injected at high pressure.
- Very good surface finish in order of 1 micron can be obtained.
- The surface generated by the die casting process is directly electroplated without further processing.
- Dimensional tolerance is very close in order n between +0.08 to -0.08 can be obtained.
- The die has a long life.
- Inserts can be readily cast in place.
- This process is very economical for large scale production.
- It will give better mechanical properties compared to sand casting.
Disadvantages of die casting :
- Material limitations all material and alloy can not be cast.
- The cost of the machine dies and other equipment is high.
- Not economical for small quantity production.
- Heavy casting can't be cast by this process.
- Limited to high-fluidity metals.
- The air in the die cavity gets trapped inside the casting causes a problem of porosity.
