Thermal Management Parts
CNCALPARTS specializes exclusively in custom aluminum CNC machining. This category covers the thermal management components we manufacture every day — heat sinks, cooling plates, cold plates, and thermal housings — engineered for flatness, fin integrity, and consistent heat transfer.

Focused on Aluminum Thermal Components
Thermal parts are unforgiving of inconsistency. Flatness affects contact resistance, fin geometry affects airflow, and wall thickness affects both weight and heat spreading. Because aluminum is our only material focus, we control the cutting conditions, workholding, and deformation behavior that these parts demand.
From single prototypes to repeat production, CNCALPARTS machines aluminum heat sinks, cooling plates, cold plates, and thermal housings to your drawings, tolerances, and surface requirements.
Flatness & Parallelism Control
Datum-driven setups and controlled cutting sequences hold flatness and parallelism down to 0.02 mm on plates and bases.
Thin-Wall & Fin Machining
Minimum wall thickness of 0.5 mm with careful chip evacuation and heat management to protect fin integrity.
Anodizing-Ready Surfaces
Surface condition and dimensions are prepared for clear, black, color, or hard anodizing without surprises.
Capabilities for Thermal Parts
Thermal management components often combine tight tolerances, large pockets, thin walls, and cosmetic requirements. Our equipment and process planning are built around these conditions.
