Comparison of High Pressure Die Casting, Low Pressure Die Casting, and Gravity Casting
HPDC vs LPDC vs Gravity Casting
HPDC: High-pressure (10-200MPa) for thin-wall mass production (e.g., auto parts), efficient but porous. LPDC: Gas-driven (0.5-1bar), dense grains for load-bearing parts. Gravity: Low-cost for thick-wall small batches. Key: Cost (HPDC>LPDC>Gravity), quality (LPDC best), eco-friendly.2025-05-21
