Die casting, as a metal casting process, can be divided into the following main types according to technical characteristics and application scenarios:
Traditional die casting process
This is the most basic die casting method, which uses high pressure to inject molten metal into the mold cavity at high speed and cool it under pressure. It is characterized by high production efficiency and high dimensional accuracy of castings, but it is easy to produce defects such as pores.
Non-porous die casting process
This is an improved process of traditional die casting. By optimizing process parameters and mold design, it reduces pore defects in castings and improves the density and mechanical properties of castings.
Direct injection process
It is mainly used for processing metals such as zinc. It reduces waste and improves the yield rate by direct injection. This process has significant advantages in improving material utilization and reducing costs.
Precision speed and density die casting technology
Invented by General Dynamics, it further improves the precision and surface quality of castings by precisely controlling the pressure and speed during the die casting process. This technology is particularly suitable for the manufacture of parts with high precision requirements.
Semi-solid die casting
This is a new die casting process that uses semi-solid metal slurry for die casting, which can effectively reduce casting defects and improve the mechanical properties and surface quality of castings. This process has broad application prospects in the manufacture of high-performance alloy castings.
