Bespoke Investment Castings for AI Data Centre Liquid Cooling

Your Component. Our Casting Expertise.

 

If you have a complex component that is currently:

• CNC machined from solid

• fabricated from multiple pieces

• welded

• forged

• difficult or expensive to manufacture

• no longer available from your existing supplier

• being produced at an unsustainable cost

​

Giayoung can assess whether investment casting can provide a better manufacturing solution.

Our engineers work with your design to develop a production-ready casting while maintaining the critical dimensions, material properties and functional requirements of the finished component.

​

From your drawing to a finished, inspected component.​

Bespoke Castings for Liquid Cooling Systems

Pump Castings

We manufacture complex pump castings where hydraulic geometry, dimensional accuracy and material performance are critical.

​

Typical components include:

​

• Pump bodies

• Pump housings

• Volutes

• Impellers

• Diffusers

• Covers

• Bespoke hydraulic components

​

Investment casting can reproduce complex hydraulic geometry while reducing machining and material waste compared with manufacturing the entire component from solid.

 

Have a pump component currently machined from solid?

Send us the drawing and we'll assess its casting feasibility.

​

Valve Castings

Liquid cooling systems depend on reliable control of coolant flow throughout the system.

Giayoung manufactures bespoke valve castings to customer drawings and specifications, including complex pressure-containing and flow-control geometries.

​

Typical components include:

• Valve bodies

• Bonnets

• Covers

• Flow-control bodies

• Actuator interfaces

• Bespoke valve components

​

Components can be manufactured in stainless steels, duplex and other alloys selected for the operating environment.

​

​

Bespoke Fluid Manifolds

Complex liquid-cooling systems require controlled distribution of coolant between pumps, heat exchangers, cooling loops and high-density computing equipment.

​

Investment casting can provide an effective manufacturing solution for complex multi-port fluid manifolds and distribution bodies, particularly where internal passages or multiple machined connections make conventional manufacture expensive.

​

We manufacture the manifold to your design not from a standard catalogue.

​

​

​

Bespoke Castings for Coolant Distribution Units (CDUs)

Coolant Distribution Units are central to direct liquid cooling in high-density AI data centres.

Depending on the system design, CDUs incorporate pumps, valves, filters, heat exchangers and fluid-distribution hardware.

​

Giayoung manufactures the bespoke cast metal components within these systems, made to customer drawings and specifications.

 

This can include complex pump, valve, manifold and fluid-control geometries where conventional machining or fabrication may be inefficient.

​​

​

​

Materials for Demanding Fluid Environments

The material used for a liquid-cooling component must be selected according to the coolant, pressure, temperature, corrosion conditions and operating environment.

​

Giayoung manufactures bespoke investment castings in a range of engineering alloys, including:

​

Stainless Steels

For corrosion resistance and demanding fluid-control applications.

​

Duplex & Super Duplex Stainless Steels

For applications requiring increased strength and enhanced resistance to corrosion.

​

High-Alloy Materials

For demanding operating environments where conventional materials may be unsuitable.

Material selection is based on your specification and the requirements of the finished component.

​​

​

Engineering for manufacturability

Can your existing component be manufactured more efficiently as an investment casting?

The most expensive way to manufacture a casting is to treat it simply as a drawing to be reproduced.

Giayoung works with customers during the engineering stage to identify opportunities to improve manufacturability, reduce machining and simplify production.

​

We assess:

• Wall thickness

• Hydraulic geometry

• Core requirements

• Draft and casting geometry

• Gating and feeding

• Machining allowances

• Critical tolerances

• Inspection requirements

• Material selection

• Component consolidation

​

Where appropriate, we can help convert components originally designed for:

​

CNC machining → Investment casting

Fabrication → Investment casting

Multi-piece assemblies → Single cast component

Forging → Investment casting

​

The objective is not simply to cast the component. It's to manufacture it more efficiently without compromising its performance.

​

From Prototype to Production

Giayoung supports customers through the complete manufacturing process.​

​

01 Engineering review

Send us your drawing, 3D model, existing component or specification.

We assess whether investment casting is appropriate and identify potential manufacturing improvements.

​

02 Casting development

Our engineers develop the tooling, gating, feeding and ceramic-core requirements needed to reproduce the component accurately.

​

03 Prototype & validation

Initial castings are manufactured and inspected against the agreed specification.

​

04 Machining

Where required, castings can be CNC machined to your finished dimensions and tolerances.

​

05 Inspection & testing

Inspection and testing are established according to the component's function and customer requirements.

​

06 Repeat production

Once approved, the manufacturing process is controlled to provide consistent repeat production and full traceability.

​​

​

Quality when the component matters

AI data-centre cooling systems operate continuously and protect high-value computing infrastructure.

The components within those systems therefore need to be manufactured consistently and verified against defined requirements.

​

Giayoung's inspection and testing capabilities can include:

• CMM dimensional inspection

• 3D and contour inspection

• Visual inspection

• Endoscopic inspection

• Material verification

• Heat-treatment control

• Non-destructive testing

• Air-tightness testing

• Pressure testing

• Surface inspection

• Full material and production traceability

​

Inspection and testing are specified according to the component, material and customer requirements.

A Bespoke Casting Partner for Your Engineering Team​

You don't need to redesign your product around our manufacturing process.

We work with your existing engineering requirements and help determine whether investment casting is the right manufacturing route.

​

Whether you are developing:

• an AI data-centre liquid-cooling system

• a coolant distribution unit

• a high-performance pump

• a specialist valve

• a fluid manifold

• a thermal-management system

• or another complex fluid-control application

​

We can assess your component and develop a manufacturing route around your requirements.

​

Have a difficult component that needs manufacturing?

Have a pump component currently machined from solid? Send us the drawing and we'll assess its casting feasibility.

​

Our engineering team will review:​

Casting feasibility · Material · Geometry · Machining · Inspection · Production route

We advise whether Giayoung can manufacture the component more efficiently through investment casting.
