Why Choose Investment Casting for Heatsinks?
Design Flexibility
Investment casting allows near-net-shape production of complex heatsink geometries that are impossible or cost-prohibitive with extrusion or traditional machining. This includes:
- Internal cooling channels
- Integrated mounting brackets
- Variable fin density and orientation
- Thin-wall fin structures (down to 0.5mm)
Cost Efficiency
For low-to-medium volume production and prototype-to-production transitions, investment casting offers lower tooling costs compared to die-casting or extrusion dies, especially for complex stainless steel heatsink designs.
Technical Capabilities & Quality Assurance
We provide complete documentation packages for every stainless steel heatsink order:
- Dimensional inspection reports (CMM measurement)
- Material certificates (Mill Test Certificate / EN 10204 3.1)
- Chemical composition analysis
- Thermal performance simulation reports
- Surface roughness and passivation test reports
- X-ray or dye penetrant inspection (upon request)

Frequently Asked Questions (FAQ)
|
Q1: |
What is the minimum order quantity for custom stainless steel heatsinks? |
|
A1: |
We accept prototype orders starting from 10–50 pieces. Volume production MOQ depends on heatsink size and complexity. |
|
Q2: |
Can you produce heatsinks with internal cooling channels? |
|
A2: |
Yes. Investment casting enables complex internal geometries including cooling channels and hollow structures. |
