Custom manufacturing
Custom Extruded Heat Sinks Made to Customer Drawings
BY Thermal supports B2B engineers, purchasing teams and product development teams with aluminum extruded heat sinks manufactured according to project drawings. The heat sink profile, mounting interface, contact surface, finishing and assembly requirements should be reviewed from the drawing package before production.
Extruded heat sinks are used when the customer’s product requires a dedicated aluminum profile with defined fin geometry, base structure, mounting direction and installation space. CNC secondary machining and assembly steps can be added according to the confirmed drawing.
Custom profile tooling
Custom Extrusion Tooling for Project-Specific Heat Sink Profiles
Most extruded heat sink projects require a profile designed around the customer’s product structure, installation space and thermal path. BY Thermal reviews the 2D/3D drawing to evaluate the extrusion profile, tooling requirements, CNC machining features and finishing route before quotation.
Profile Designed Around Your Product
The fin structure, base thickness, mounting direction and installation envelope should be reviewed according to the customer’s product drawing, not selected from a generic catalog shape.
Tooling Review Before Quotation
For a new extruded heat sink profile, the drawing package should define the cross-section, critical contact areas, machining needs and surface treatment requirements for tooling review.
CNC Features After Extrusion
After extrusion, CNC machining can be used for holes, slots, grooves, cutouts, steps, threaded features and contact surfaces according to the confirmed drawing.
Tooling and profile review
Extrusion Tooling and Profile Review
For new custom profiles, BY Thermal reviews the drawing to understand fin structure, base shape, mounting interfaces, profile length, contact areas and later machining requirements. This review helps evaluate whether the custom aluminum extrusion profile can match the product structure and manufacturing route.
- Profile cross-section and fin direction review
- Mounting holes, slots, grooves and cutout planning
- Heat pipe or assembly interface review where required
- Surface finish and appearance requirements checked from the drawing
Machining and assembly
CNC Secondary Machining and Heat Pipe Integration
Extruded heat sinks often require additional machining and assembly after extrusion. BY Thermal reviews the required secondary processes from the customer drawing.
CNC Secondary Machining
CNC machining can create mounting holes, threaded features, grooves, cutouts, pockets, steps and contact surfaces according to the drawing. Machining access and datum requirements should be reviewed before production.
CNC-machined thermal partsExtruded Heat Sinks with Heat Pipes
Heat pipes can be integrated into selected extruded heat sink assemblies when the project requires heat spreading from a concentrated or offset heat source. Heat pipe route, groove design, contact method and assembly direction should be confirmed with the drawing.
Heat pipe heat sinksMaterial and finish
Aluminum Materials and Surface Treatments
Extruded heat sink projects should define material grade, surface finish, appearance requirements and any electrical or assembly requirements in the drawing or RFQ package. BY Thermal can review aluminum extrusion material and finishing requirements based on the project documentation.
Aluminum Extrusion Material
Material selection should be reviewed according to mechanical structure, thermal path, surface treatment and assembly needs.
Surface Finishing
Anodizing, conductive conversion coating, painting or other project-specific finishes can be reviewed when specified by the drawing.
Contact Surfaces
Machined contact areas, mounting relationships and interface surfaces should be marked clearly in the drawing package.
Assembly Requirements
Heat pipes, inserts, fasteners or other assembly requirements should be defined before quotation and production review.
RFQ preparation
Design Information Required for Quotation
A clear drawing package helps BY Thermal review the manufacturing route and prepare a more useful RFQ response.

FAQ
Custom Extruded Heat Sink FAQ
Do you manufacture custom extruded heat sinks from customer drawings?
Yes. BY Thermal can review customer 2D/3D drawings and manufacture aluminum extruded heat sinks with project-specific machining, finishing and assembly requirements.
Do custom extruded heat sinks usually require new tooling?
For most project-specific extruded heat sink designs, the profile is reviewed around the customer’s product structure and may require dedicated extrusion tooling before production.
Can CNC machining be added after extrusion?
Yes. CNC secondary machining can be used for holes, grooves, steps, cutouts, pockets, threads and contact surfaces according to the drawing.
Can extruded heat sinks include heat pipes?
Yes, when the design supports heat pipe integration. Heat pipe route, grooves, contact method and assembly direction should be confirmed during drawing review.
What aluminum materials can be used?
The aluminum material grade should be specified in the drawing or RFQ package. BY Thermal can review material requirements based on the project documentation.
What surface treatments can be reviewed?
Surface treatment options such as anodizing, conductive conversion coating, painting or other specified finishes can be reviewed when they are included in the project requirements.
What information is needed for quotation?
Please provide 2D/3D drawings, profile requirements, machining details, material and finish requirements, application information, target quantity and any inspection or packaging requirements.
