Basic Principles and Characteristics of Die Casting
Common Fluid Principles and Applications
Overview of Liquid Metal Filling Theory
Flow State and Characteristics of Liquid Metal
Die Casting Process Cycle
Semi-automatic die casting cycle: Clean the mold → Spray → Place inserts → Close the mold → Pour material → Inject → Cool and solidify → Open the mold → Eject → Take the part
Automatic die casting cycle: (Same steps as semi-automatic)
Conditions Related to Die Casting Production
Die casting design: Requirements (performance, appearance); Structure (fillets, draft angles, wall thickness, holes); Gating system design
Die casting operation: Keep in normal state; Coating (type, spray amount); Die casting cycle; Mold temperature
Die casting process: Specific pressure, filling speed, filling time; Process parameters
Mold: Material and heat treatment; Machining accuracy; Design; Maintenance
Alloy material and melting: Furnace charge ratio; Alloy composition; Flux usage; Temperature control; Cleanliness (gas, hard spots, foreign matter); Ratio of return material
Die caster: Safe operation; Professional knowledge; Proficiency; Dedication; Physical strength
