2026: New Year, New Goals with focus of Large and Heavy Castings

For Woosung Metal Company, this year is not about changing direction or making loud announcements. Our focus remains practical and consistent: manufacturing large, technically demanding castings and underground lining systems, with full control over quality and delivery.

Over recent years, our work has become more focused. We take on fewer generic enquiries and spend more time on projects where engineering input, manufacturing discipline, and predictability are genuinely important.

Manufacturing in South Korea

All casting and machining operations are carried out in South Korea.

This allows us to directly control:

• melt practice and metallurgical consistency

• moulding and pouring parameters

• machining accuracy and tolerances

• inspection and final acceptance

There is no outsourcing of critical manufacturing steps. For customers, this usually means fewer unexpected issues during production and more stable project execution.

Large and Heavy Castings

One of our main focus areas in 2026 remains one-piece heavy castings up to 80 tons.

These are typically components where welded fabrications are technically possible but introduce long-term risks related to fatigue, distortion, or maintenance. Producing them as single castings simplifies installation and improves operational reliability.

Typical applications include:

• turbine and power-generation housings

• large gearbox and drive frames

• slag pots, ladles, and furnace components

• bases and structural castings for heavy machinery

Such components require careful coordination between casting design, feeding systems, heat treatment, and machining. Experience and process stability matter more here than speed alone.

SGI Tunnel and Mine Shaft Linings

We continue to manufacture SGI (ductile iron) lining segments for underground projects.

This includes:

• mine shaft linings

• tunnel eyes and junctions

• cross passages and opening sets

• applications requiring watertight performance under pressure

Each project is engineered individually based on geology, loading conditions, and construction method. There are no standard “off-the-shelf” solutions for these applications.

Inspection and Documentation

Inspection is part of the normal production process. Chemical analysis, mechanical testing, dimensional checks, ultrasonic testing, and test assembly are performed according to agreed inspection plans.

Customer representatives and independent inspection agencies are regularly involved during production. Documentation is prepared alongside manufacturing, not retrospectively.

Lead Times and Planning

For new projects, a typical timeline remains:

• contract and commercial alignment: around 4 weeks

• design finalisation and approvals: around 8 weeks

• trial batch and mobilisation: around 8 weeks

This allows first deliveries in approximately 20 weeks, depending on scope and complexity. We prefer to set realistic timelines early and keep them stable throughout the project.

Project Selection

Not every enquiry is the right fit, and we are transparent about this.

In 2026, we primarily focus on projects where:

• the technical scope is clearly defined

• engineering discussion happens early

• quality and reliability are prioritised

• there is potential for repeat or long-term cooperation

This approach allows us to stay technically involved and responsive, rather than spreading resources too thin.

Looking Ahead

2026 is about steady, controlled progress. No radical changes — just consistent work on demanding projects in tunnelling, mining, energy, and heavy industry.

If you are planning a project involving large castings or SGI lining systems and want to discuss it at an early stage, we are always open to a technical conversation.

That is often where the best results begin.
