Process the liquid metal material under high pressure, and when it cools down, it will become relatively qualified casting.
When the metal liquid is processed, it will bear high pressure, and its flow rate is also very fast. So the quality of pressure custom casting is better.
Moreover, the production efficiency of pressure custom castings is very high, and the products can be used for much more times; so it is more suitable for large-scale production, which will bring more benefits.
Of course, pressure custom castings also have shortcomings, first of all, they are more prone to small pores or shrinkage phenomenon. The plasticity of the die casting is relatively low, and it is not suitable to work in the impact load and vibration situation.
