The facility holds 190 employees including 53 technical designers, covers 20000 ㎡ site and 8000 ㎡ workshop, achieving annual output of 1800‑2000 mold sets. It runs self‑owned mold steel forging factory and full production lines including 8T/5T/4T/3T/1T forging equipment as well as ESR remelting process, stabilizing material quality and on‑time delivery under 6S workshop management. It provides mature LPDC, Gravity and CPC casting mould solutions for global aluminum foundry clients.

Many foundry engineers compare A380 aluminum die‑casting mold and ADC12 aluminum alloy die‑casting mold components; silicon content difference changes melt abrasion feature. A380 cannot be used for low‑pressure casting directly; J45 low‑pressure casting mold machine cannot satisfy high‑pressure die‑casting injection requirement. Some factories try to modify existing 6061 aluminum alloy die‑casting mold for A380; practical data show reject rate rises to 24%. When running mass‑production, inspect vent‑slot clogging every 20 000 shots; clogged vent will push gas porosity sharply. Procurement teams should confirm supplier owns in‑house mold trial capacity; third‑party trial raises parameter‑mismatch risk by 22%. A380 die‑casting parts are non‑structural components; do not substitute A356 casting aluminum for safety‑critical knuckle‑type parts. Simulation before mold machining reduces post‑modification workload by 40%. AlSi8 die‑cast aluminum has similar fluidity yet different silicon percentage versus A380 alloy.
