Other Profile Heat Sink CNC Machining
Other Profile Heat Sink CNC Machining
CNC machining of non-standard extruded aluminium profile heat sinks, covering custom cross-sections, irregular fin patterns and application-specific mounting features.
Product Overview
Custom Profiles Machined to Your Application
Off-the-shelf profiles rarely fit every design. We manufacture custom extruded sections and machine the critical features afterwards, so the heat sink fits the enclosure, the mounting pattern and the thermal path you have designed for.
Zhigao is a manufacturer of other profile 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.
