Machined heat sinks from a controlled drawing
Machined heat sinks may include a base, fins, mounting features and interfaces for an electronic or mechanical assembly. The drawing should define the geometry and material required for the part. Machining alone does not guarantee a temperature drop or overall thermal performance.
Specify the features that affect assembly
Show the base dimensions, fin spacing and height, mounting pattern, locating features and any areas that contact another component. Identify flatness or surface-finish requirements only where they affect the thermal interface or assembly. State the material grade and any coating, anodizing or masking requirement.
Explain the operating context
If thermal behavior matters, provide the design conditions and system-level acceptance plan to the responsible engineering team. Thermal transfer depends on material, geometry, airflow, contact resistance, heat source, installation and other system factors. A machined part should not be described as meeting a performance target without test evidence.
Prepare an RFQ
- Current drawing and 3D model with revision
- Material grade, quantity and approved alternatives
- Fin, base, mounting and contact-interface dimensions
- Surface treatment, color and masked areas
- Inspection features, packaging and destination
For prismatic features, see the CNC milling service. If the design includes different materials or finishing operations, state which items must be included in the quotation.
Confirm the final part requirements
Review the drawing revision, critical dimensions, finish and acceptance criteria before production. Validate thermal performance in the assembled system using the project's measurement method.
To request a quote, submit the drawing package, material, quantity and inspection expectations through the custom CNC machining quote page.
