Case Study: Aluminum Die Casting Heat Sink for Automotive Applications

Complex Aluminum Casting Component Manufactured from Customer Design

A global automotive customer required a manufacturing partner to produce an aluminum heat sink component for their electronic system.

The customer provided:

• Product drawings
• 3D CAD files

Before tooling development, YS Precision performed a detailed DFM review to evaluate:

• Casting feasibility
• Mold structure
• Material flow
• Manufacturing risks

After engineering validation, we developed the aluminum die casting mold and supported:

• Die casting production
• CNC precision machining
• Surface finishing

Production requirement:

Approximately 3,000 Sets per Production Batch

for international delivery.

Project Overview

Engineering Challenge: Reducing Die Casting Tooling Risk

DFM Analysis Before Mold Manufacturing

Die casting tooling requires significant investment.

Unlike CNC machining, major design changes after mold completion can be expensive and time-consuming.

Therefore, early engineering review is critical.

YS Precision evaluates:

Parting Line Design

To ensure:

• Proper mold opening
• Easy demolding
• Stable production

Draft Angle Optimization

To reduce:

• Ejection problems
• Surface damage
• Mold wear

Wall Thickness and Material Flow

To minimize:

• Porosity
• Shrinkage
• Casting defects

Heat Sink Fin Structure

For cooling components, we analyze:

• Filling performance
• Mold durability
• Thermal design requirements

Aluminum Die Casting Manufacturing Process

1. Engineering Review & DFM

Before tooling begins:

• Customer drawings are reviewed
• Casting risks are identified
• Manufacturing improvements are suggested

2. Die Casting Mold Development

After DFM approval:

• Mold design
• Tool manufacturing
• Trial casting

are completed.

3. Aluminum Die Casting Production

Production control includes:

• Casting parameter control
• Surface inspection
• Process monitoring

4. CNC Secondary Machining

After casting:

Critical features are CNC machined:

• Mounting holes
• Precision surfaces
• Assembly areas

5. Surface Finishing

Final processing includes:

• Polishing
• Deburring
• Passivation
• Painting
