Die Casting: High-Efficiency Precision Metal Forming
Die casting (pressure casting) is an efficient, precision metal-forming process. Its core principle: Injecting molten/semi-molten metal (e.g., aluminum/zinc/magnesium alloys) under high pressure (tens to hundreds of MPa) and high velocity into precision metal dies. The metal rapidly solidifies under pressure, forming near-net-shape components. The die determines final geometry, dimensions, and surface quality.
Key Advantages of Die Casting:
Ultra-High Productivity
Fully mechanized/automated process with short cycle times (seconds to minutes), ideal for mass production—yielding hundreds to thousands of parts hourly.
Complex Thin-Wall Capability
High pressure/velocity fills intricate cavities, producing parts with: Complex geometries Ultra-thin walls (0.5mm for Al / 0.3mm for Zn alloys) —unattainable by other casting methods.
Enhanced Strength & Density
High pressure refines grain structure during solidification, improving mechanical properties (strength/hardness) and density.
Exceptional Precision & Surface Finish
High-pressure filling replicates die details precisely. Achieves:
High tooling costs offset by extreme efficiency and material recycling, delivering low per-unit costs at scale. Our die-cast components serve: Automotive (engine blocks, transmission housings, structural parts) | 3C electronics (phone/laptop casings, brackets) | Power tools | Appliances | Hardware

Injection Molding Production Process
Intensification & Cooling
After cavity fill: Intensification pressure maintains solidification under compression → Enhances density while minimizing shrinkage Circulating water rapidly cools the mold.
Mold Preparation & Preheating
Mounting precision-crafted metal molds (ejector & stationary dies) onto the die-casting machine. Preheating prevents premature solidification defects in molten metal.
Metal Melting & Holding
Heating alloys (Al/Zn/Mg) to molten state in furnaces, then transferring to the machine’s holding furnace for temperature maintenance.
Clamping & Injection
Dies securely close Injection plunger forces metered molten metal at high pressure (tens-hundreds MPa) and high velocity into the cavity through the gating system.
Intensification & Cooling
After cavity fill:
Intensification pressure maintains solidification under compression → Enhances density while minimizing shrinkage Circulating water rapidly cools the mold.
Mold Opening & Ejection
Post-solidification: Moving die retracts Ejector pins push the casting out.
