Dongchuan Recycled-metal Resources Cluster

Dongchuan received provincial recognition as an SME speciality cluster in 2025. Its practical chain separates recoverable metal from discarded products and routes it into regulated remelting; not every park tenant performs the same kind of recycling. Huazaixinyuan dismantles old appliances, while Dianyu and Zhongli are separately named recycled-aluminium businesses. A 2026 park report gives a combined output for the latter two, not a company-specific figure. Buyers of alloy ingots should verify scrap origin, grade and composition, lot tests, furnace approvals and environmental permits. For dismantled material, check the dismantling licence, saleable fractions and hazardous-part disposal. Tianshengqiao is a Dongchuan–Xundian cooperative area, not wholly within Dongchuan District.

This chapter reviews production stages and engineering interfaces in Dongchuan Industrial Park and the Dongchuan–Xundian cooperative Tianshengqiao…

Operating sequence: dismantling and hazardous-part segregation, metal sorting, pretreatment, remelting, composition adjustment and ingot casting.

After a change to dismantling and hazardous-part segregation, reassess used-appliance dismantling acceptance criteria and update records for process revisions, equipment settings, stage results and responsibility boundaries.

Before dismantling and hazardous-part segregation in Yunnan moves to sorted secondary copper, use a limited trial, test harvest or stage result to confirm the output boundary.

  • Before work in Dongchuan Industrial Park and the Dongchuan–Xundian cooperative Tianshengqiao area moves into execution, equipment, software versions and accountable owners should be explicit.

03 · Dongchuan Recycled-metal Resources Cluster: Outputs and acceptance

This chapter reviews output forms and acceptance measures in Dongchuan Industrial Park and the Dongchuan–Xundian cooperative Tianshengqiao area.

Output range: sorted secondary copper, iron and aluminium feedstocks, plus grade-specified recycled aluminium-alloy ingots.

Acceptance of sorted secondary copper from dismantling and hazardous-part segregation in Yunnan should specify reproducible samples, methods, environments and decision rules.

For Dongchuan Recycled-metal Resources Cluster, quote sorted secondary copper separately by model, custom scope, technical files and site services.

  • Before work in Dongchuan Industrial Park and the Dongchuan–Xundian cooperative Tianshengqiao area moves into execution, specifications, test environments and delivery documents should be explicit.

04 · Dongchuan Recycled-metal Resources Cluster: Demand and purchasing

This chapter reviews demand side and purchasing routes in Dongchuan Industrial Park and the Dongchuan–Xundian cooperative Tianshengqiao area.

Demand side: licensed metals recyclers, extrusion and die-casting manufacturers, and material buyers requiring lot traceability.

In Yunnan, demand from licensed metals recyclers can be separated by assembly, operating environment, production cadence and support conditions, then matched to the conditions for sorted secondary copper.

An inquiry for sorted secondary copper in Dongchuan Recycled-metal Resources Cluster should state volume, acceptance and delivery terms for licensed metals recyclers.

  • Before work in Dongchuan Industrial Park and the Dongchuan–Xundian cooperative Tianshengqiao area moves into execution, use case, volume range and acceptance owner should be explicit.
