Aluminium cooling components
Heat sinks shaped around your product
As an aluminium heat sink manufacturer in India, we focus on gravity die cast solutions for geometry that is difficult or uneconomical to produce from a continuous extrusion profile. The process can combine fins, bosses, mounting points, covers and enclosure walls in a single cast component.
Customers searching for an aluminum heatsink or aluminum heat sink are looking for the same product; “aluminium” is the standard spelling used in India. Every enquiry is reviewed against the drawing, annual quantity, dimensional needs and operating environment before a manufacturing route is proposed.
- Custom aluminium fin and finned heat sink configurations
- Wide or non-symmetrical cooling components
- Heat sink and electrical enclosure integration
- Machined mounting faces, holes and component interfaces

Manufacturing capabilities
From heat sink concept to finished casting
Our foundry and machine-shop capability supports custom OEM heat sink development, with practical input on castability, weight and secondary operations.
Cast Fin Geometry
Application-led aluminium fin heat sink layouts, developed within gravity casting design limits.
Machined Features
Machining of mounting faces, holes, bosses and interfaces where the assembly requires controlled fits.
Die Design & Making
Tool development informed by the part geometry, casting flow and production requirement.
Part Integration
Potential to combine a cooling body with covers, brackets or enclosures and reduce separate parts.
Value Engineering
Review of existing sand-cast or heavily machined components for gravity die casting conversion.
Choose the right process
Cast, extruded or CNC-machined heat sink?
The correct manufacturing route depends on shape, volume and performance—not on a keyword. We specialise in gravity die cast heat sinks and assess where they offer a practical advantage.
| Route | Often suited to | Design consideration |
|---|---|---|
| Gravity die cast aluminium | Wide, non-symmetrical, three-dimensional or enclosure-integrated heat sinks | Requires casting-friendly fin, draft and wall geometry |
| Aluminium extrusion | Long, constant cross-section profiles and conventional parallel fin arrays | Complex local features may require cutting, drilling or additional machining |
| CNC machined aluminium | Prototype, low-volume or very specific geometry machined from stock | Material removal and machining time can affect unit cost |
If your drawing currently specifies an aluminium extrusion heat sink, custom extruded heat sink or CNC-machined aluminium heat sink, send it for a manufacturing review. Where extrusion is clearly the better route, the project may not suit our gravity die casting process.
Thermal management applications
Built for electrical and industrial equipment
Custom aluminium heat sinks help conduct and dissipate heat from components into the surrounding air. Final thermal performance depends on the full system design, airflow, interface material, orientation and operating conditions.
Power Electronics
Cooling bodies for converters, rectifiers, drives and power-control assemblies.
LED Lighting
Aluminium LED heat sink castings for luminaires and industrial lighting housings.
Electrical Systems
Heat-dissipating cast parts for control and electrical applications.
Industrial Equipment
Custom cooling components and integrated enclosures for demanding machinery.
OEM project workflow

Frequently asked questions
Custom aluminium heat sinks
Do you manufacture custom aluminium heat sinks?
Yes. Gravity Diecasting develops custom gravity die cast aluminium heat sinks from customer drawings, samples or application requirements, subject to design and feasibility review.
Are you an aluminium heat sink supplier in India?
We manufacture aluminium gravity die cast heat sink components from our facility in Kalyan, Maharashtra, and support OEM enquiries from across India.
When is a die cast heat sink preferred to an extruded heat sink?
Gravity die casting can suit wide, non-symmetrical or enclosure-integrated parts where an extruded profile would need substantial secondary machining or assembly. Conventional constant-section profiles often remain better suited to extrusion.
Can a heat sink include machined features?
Yes. Mounting faces, holes, bosses and component interfaces can be reviewed for machining. Tolerances and inspection requirements should be supplied with the enquiry.
What should I send for a quotation?
Please send a dimensioned drawing or 3D model, required quantity, alloy or performance requirements, target weight, machining details and application notes. Thermal validation remains the responsibility of the complete system designer unless separately agreed.
Do you accept aluminium heat sink enquiries from all Indian states?
Yes. We accept OEM enquiries from all 28 states and 8 union territories. Supply is subject to technical feasibility, commercial terms and delivery arrangements, so please share the destination together with your drawing and quantity.
