What are the critical process parameters in die casting?

Critical die casting parameters include: Injection pressure (typically 10-175 MPa, affects filling and density), Injection speed (slow shot and fast shot phases), Die temperature (controls solidification and surface quality), Metal temperature (affects fluidity and cycle time), Cycle time (productivity vs quality balance), and Vacuum level (for high-integrity parts). Optimizing these parameters through DOE and simulation reduces porosity, improves surface finish, and minimizes cycle time while maintaining dimensional accuracy.
