Custom Machined Aluminum Heatsink Plates
These custom aluminum heatsink components are intended for integration into lighting and other equipment. Production is based on customer drawings or supplied samples rather than a fixed standard size. CNC machining supports the production of required profiles and features. The final structure, including any mounting holes, threads or other machined details, depends on the part drawing and confirmed manufacturing requirements.

01 Product Overview
These custom aluminum heatsink components are intended for integration into lighting and other equipment. Production is based on customer drawings or supplied samples rather than a fixed standard size.
CNC machining supports the production of required profiles and features. The final structure, including any mounting holes, threads or other machined details, depends on the part drawing and confirmed manufacturing requirements.
02 Material & Machining Specifications
The following information reflects materials and machining capabilities listed for aluminum components. Material selection and achievable tolerances must be confirmed for each heatsink drawing.
| Item | Available Information |
|---|---|
| Aluminum grades | 6061, 6082 and 7075 are listed for related aluminum LED parts. Confirm the suitable grade for each heatsink application. |
| Other aluminum grades | 5052 and 6063 are listed within general aluminum machining capabilities; availability for a specific heatsink part requires confirmation. |
| Machining processes | CNC milling, turning, drilling and tapping |
| Machining equipment | 3-axis, 4-axis and 5-axis machining centers |
| General machining tolerance | ±0.05 mm |
| Tighter tolerance | Up to ±0.01 mm for suitable features, subject to geometry, material, process and inspection requirements |
| Surface roughness | Ra 1.6–3.2 μm for standard machined surfaces; Ra 0.8–1.6 μm for fine machining |
The tolerance and surface-roughness figures above describe general aluminum machining capabilities, not guaranteed values for every heatsink feature. Confirm critical dimensions and surface requirements against the part drawing.
03 Customization & Surface Finishing
Custom CNC aluminum heatsink plates can be produced from 2D drawings, 3D files or physical samples. Depending on the design and machining feasibility, the specified work may include:
- Overall dimensions and component geometry
- Milled profiles and machined surfaces
- Drilled holes and tapped threads
- Other drawing-defined features
Anodizing in different colors is listed for the aluminum heatsink products. Sandblasting and natural-color anodizing are also listed for related aluminum parts; confirm the required finish and its availability for the specific component before ordering.
04 Manufacturing & Quality Control
Production can involve CNC milling, turning, drilling, tapping and multi-axis machining, depending on the part geometry.
Before production, confirm the material grade, critical dimensions, hole and thread requirements, surface condition and finishing details against the approved drawing. Any tighter tolerances or special inspection requirements should be agreed before the order is placed.
05 Production & Supply Support
The company's general aluminum machining capabilities cover prototype, small-batch and repeat production. Small orders are also accepted for related aluminum LED parts; confirm the minimum order quantity and production arrangement for the specific heatsink component.
Production is carried out at the company's own factory in Dongguan, China. Order quantity, lead time, packaging and delivery arrangements should be confirmed according to the drawing, finishing requirements and order scope.
06 Request a Quote
Send your 2D or 3D drawing, sample or part specifications for a manufacturing review and quotation.
To help assess the part, include the required aluminum grade, overall dimensions, critical tolerances, machined features, anodizing color, order quantity and expected delivery schedule. Any application-specific requirements should also be stated so they can be reviewed before production.
