LED Heat Sink CNC Machining
LED Heat Sink CNC Machining
CNC machined LED heat sinks produced from aluminium extrusions, delivering the flatness, hole accuracy and surface finish required for reliable LED thermal management in lighting fixtures.













Product Overview
Engineered Heat Dissipation for LED Lighting
LED efficacy depends on keeping junction temperature under control. Our extruded and CNC machined heat sinks are produced with controlled flatness and precise mounting hole positions so that thermal contact resistance stays low and light output remains stable over the product lifetime.
Zhigao is a manufacturer of led heat sink cnc machining serving customers in Europe, North America and Asia. Every order is produced to your drawing and inspected against your specification before shipment, with full documentation supplied.
