Product Description

Service Process for Extruded Aluminum Heat Sink for LED Lighting

1. Pre-Production Collaboration

(1) Requirement Confirmation
Confirm heat sink specifications including profile cross-section design, fin height and spacing, overall length, tolerance requirements, aluminum alloy grade, surface finish, order quantity, and delivery schedule.

(2) Drawing & File Review
Receive profile drawings or 3D models showing fin structure, mounting interfaces, and key dimensions for LED lighting applications.

(3) Design & Feasibility Review
Evaluate extrusion feasibility and cooling performance. Optimize fin layout and profile structure to balance heat dissipation efficiency and extrusion stability.

2. Tooling & Aluminum Extrusion Planning

(1) Die Design & Preparation
Design and manufacture extrusion dies according to approved heat sink profile drawings, ensuring smooth material flow and consistent fin geometry.

(2) Material Selection
Select suitable aluminum alloys such as 6063 or 6061 based on thermal conductivity, extrudability, and surface treatment requirements.

(3) Extrusion Parameter Setup
Set extrusion temperature, speed, and cooling methods to ensure dimensional accuracy and stable heat sink performance.

3. Extrusion Production & Quality Control

(1) Aluminum Extrusion
Extrude aluminum billets through precision dies to form continuous heat sink profiles with uniform fin structure.

(2) Cutting & Straightening
Cut extruded profiles to specified lengths and perform straightening to meet assembly and installation tolerances.

(3) Inspection & Testing
Inspect profile dimensions, fin spacing, straightness, and surface condition. Visual checks ensure clean fins and consistent quality.

4. Post-Processing & Delivery

(1) Surface Treatment
Apply anodizing or other surface finishes to improve corrosion resistance and heat radiation performance for LED lighting.

(2) Secondary Machining (Optional)
Provide CNC machining such as drilling, tapping, or slotting for LED module mounting and assembly.

(3) Packaging & Delivery
Pack heat sinks with protective materials and deliver according to agreed logistics methods for both prototype and mass production orders.
