Advantage
1) High productivity, easy to realize mechanization and automation, and can produce thin-walled castings with complex shapes. The minimum wall thickness of die-casting zinc alloy is only 0.3mm, the minimum wall thickness of die-casting aluminum alloy is about 0.5mm, and the minimum casting hole diameter is 0.7mm.
2) The casting has high dimensional accuracy and small surface roughness. The dimensional tolerance level of die castings can reach CT3~CT6, and the surface roughness is generally Ra0.8~3.2μm.
3) Parts can be embedded in die castings, which not only saves precious materials and machining time, but also replaces the assembly process of components, which can save assembly processes and simplify manufacturing processes.

2. Disadvantages of pressure casting
1) During die casting, the filling speed of liquid metal is high, and it is difficult to completely remove the gas in the cavity. The castings are prone to defects such as pores, cracks, and oxidation disasters. Die castings usually cannot be heat treated.
2) The structure of the die casting mold is complex, the manufacturing cycle is long, and the cost is high, so it is not suitable for the production of small batch castings.
3) The die-casting machine has high cost and large investment, and is limited by the clamping force of the die-casting machine and the size of the die, so it is not suitable for the production of large-scale die-casting parts.
4) The types of alloys are limited, such as zinc, magnesium, copper and other non-ferrous alloys.
