Thermal Management
Custom aluminum heatsinks & cold plates
Heat sinks are where our extrusion capability runs deepest. We build extruded, skived fin, bonded fin, CNC machined and liquid cold plate heatsinks to your thermal specification — and assemble them with heat pipes, fans and fittings.
One of our strongest extrusion branches
A heatsink is fundamentally an extruded aluminum profile with fins — so it sits naturally inside our extrusion flow. That means we control the fin geometry, base flatness and post-machining in one process, and we can move from finned extrusion to bonded, skived or liquid-cooled designs as your power density demands.
Share your power dissipation, airflow and ambient temperature and we'll propose a construction and alloy.
To choose a type, we need
- Power to dissipate (W) and hot-spot location
- Airflow (natural / forced, m/s) or liquid flow rate
- Ambient and target junction temperature
- Space envelope and mounting method
- Finish (anodized helps radiation & looks)
Heatsink types we make
From cost-effective extruded fins to high-density skived and liquid cooling.
Extruded Heatsinks
High-fin-density profiles, economical for medium power. Up to ~40:1 fin ratio.
See extruded →Extruded vs skived vs bonded — quick guidance
Extruded
- Best for medium power, high volume
- Lowest tooling cost
- Fin ratio limited (~40:1)
Skived / Bonded
- High power density, tight space
- Very thin, tall fins
- Higher piece cost, no die

Surfaces & finishes
Most heatsinks are anodized (clear or black) to improve emissivity and protect the surface; some are powder coated. We also do brushing and sandblasting for specific looks.
