INDUSTRY MODERNIZATION REFERENCE · SAND CASTING
Foundry modernization connects sand preparation, moulding, metal transfer, pouring, cooling, material handling and controls. The images below illustrate the transition from traditional manual operations to an automated moulding and integrated production line.
Before: Traditional Sand-Casting Operations
After: Automated Moulding & Integrated Production
Publicly Reported Foundry Modernization
A Guang’an government report published on 5 June 2025 describes the modernization of 四川弘融新精密铸造有限公司 in Linshui, Sichuan. The report identifies an AFM-407 wet-clay-sand double-station automatic line installed in 2024, with weighing, transfer, pouring and inspection connected through a control centre.
| Reported item | Manual stage | Automated stage |
|---|---|---|
| Pouring duty per operator per day | 2 tonnes | 40 tonnes |
| Operating model | Manual-dependent casting operations | Integrated automatic production line |
| Reported plant production | Not stated on a comparable basis | Approximately 90 tonnes / day and 40,000 components / day |
These are the cited company’s reported results, not guaranteed figures for another plant. The traditional-process images are process references; they are not presented as a verified baseline survey of that company.

What a Foundry Upgrade Can Include
- Sand preparation, return-sand handling and moulding-system interfaces.
- Equipment replacement, automated transfer, cooling and production-line balancing.
- Controls, interlocks, traceability and inspection integration.
- Fume capture, dust collection, machine guarding and maintenance access.
- Existing-building, electrical, utility and shutdown interfaces.
Engineering Workflow
- Survey existing equipment, product mix, melt duty, sand system, layout and operating constraints.
- Define required casting quality, target throughput and which assets will be retained.
- Develop the moulding, pouring, handling, environmental-control and automation interfaces.
- Plan phased installation, safe changeover, testing and operator training.
- Verify performance against the agreed casting mix, quality criteria and operating conditions.
Information for a Retrofit Proposal
Provide casting drawings and weights, metal grades, current output, scrap records, moulding and melting equipment, sand analyses, building layout, utilities, dust-control requirements, available shutdown windows and automation objectives.
