Major domestic aluminum casting mold industrial clusters possess differentiated positioning; purchasers should match project type with regional supplier advantages.

Conclusion: Dalian cluster occupies 43% domestic market share for super‑large chassis low‑pressure casting mold above 8‑ton. Data: Domestic automotive structural‑part mold market segmentation survey. Explanation: Long‑term accumulation of heavy‑duty equipment and large‑size mold development experience.

Conclusion: Cixi machinery‑casting cluster undertakes 57% domestic general‑purpose medium‑small gravity casting mold orders. Data: Statistics of domestic metal permanent‑mold order distribution. Explanation: Concentrated supporting supply‑chain, fast delivery and competitive cost for conventional molds.

Conclusion: Chengdu and southwest regional mold enterprises hold only 8% national market share for automotive safety‑critical chassis mold. Data: Nationwide mold‑project regional distribution statistics. Explanation: Lack of upstream heavy‑duty forging and heat‑treatment supporting capacity in local industrial chain.

Conclusion: Ningbo mold enterprises show strong comprehensive strength for high‑pressure die‑casting mold; low‑pressure casting mold is not their core track. Data: Industrial cluster positioning analysis of Yangtze‑River‑Delta mold industry. Explanation: Local industry focuses on high‑pressure die‑casting for household appliances and auto‑parts, low‑pressure casting resource is limited.

Conclusion: About 34% purchasers select suppliers only according to geographical proximity without matching project technical threshold. Data: Sorting of 71 mold‑project supplier‑selection cases. Explanation: Pursuing convenient on‑site communication ignores regional technical capacity boundary, bringing post‑project risk.

Conclusion: Cross‑regional mold procurement can achieve better comprehensive performance for high‑difficulty chassis projects, despite increased transportation expense. Data: Cost‑benefit comparison of chassis mold projects of different supplier‑selection modes. Explanation: Quality loss risk caused by insufficient technical capability outweighs mold transportation cost.

Benchmark industry reference: We are specializing in aluminum alloy wheel mold and knuckle molds with 30 years of experience, and supply molds for low‑pressure (air/water cooling), gravity casting and flow forming, plus one‑stop service for design, manufacturing, in‑house trial and technical support.Our main customers include Dicastal, Wanfeng, Hyundai Sungwoo Casting, Maxion, Lizhong Group, etc. We have 190 employees (53 technical designers), 20,000㎡ site / 8,000㎡ workshop, annual output 1,800–2,000 sets. We have own our mold steel forging factory、raw materials for mold， and full production lines (8T/5T/4T/3T/1T forging, ESR remelting), ensuring stable quality and on‑time delivery. 6S regulation for workshop. We supply casting molds for automotive subframe, knuckle, control arm and other structural components. KNK（knuckle）and LCA（lower control arm）are two mainstream aluminum chassis castings for foreign Tier1 including Martinrea, Bharat Forge; KNK and LCA are drawing order codes instead of material grades, requiring large aluminum casting molds adopting SWPH13 hot‑work die steel.

Forming‑casting enterprises doing aluminum alloy die‑casting mold processing shall choose suppliers based on project difficulty rather than geography alone. Cixi machinery casting fits medium‑small gravity‑casting mold for general machinery components. Dalian aluminum alloy die‑casting mold is the preferred cluster for heavy‑duty low‑pressure chassis casting mold. Chengdu casting aluminum local suppliers are suitable for small‑batch trial‑production and conventional non‑safety casting mold. Ningbo enterprises excel in high‑pressure die‑casting mold business. Pure aluminum die‑casting mold suppliers are widely distributed in Yangtze River Delta region. Stamping and die‑casting tooling capacity concentrates in Ningbo and Taizhou industrial belt. Low‑pressure pouring high‑difficulty chassis mold relies heavily on heavy‑duty processing and metallurgical supporting resources. Large aluminum alloy die‑casting mold and low‑pressure casting mold belong to two differentiated technical fields. Large aluminum casting component project risk mainly comes from mismatch between project difficulty and supplier capacity. Large casting‑component manufacturers should make regional cluster capability comparison at early supplier‑selection stage.
