Heat Sink Extrusion-FAQ's
What alloys are used for heat sink extrusions?
Common alloys include 6061 and 6063, providing high thermal conductivity and excellent extrusion capability.
Can you design custom profiles?
Yes-custom extrusion dies allow us to produce profiles with unique shapes and performance characteristics.
What finishing options do you provide?
Surface finishes include anodizing, powder coating, chromate conversion, and painting for durability and appearance.
How are extrusions processed after production?
Profiles are cut to length and can be CNC machined, drilled, tapped, or slotted as required.
Are extruded heat sinks cost-effective?
Yes-extrusion technology provides efficient, scalable, and low-cost solutions compared to skiving or forging.
What dimensions are available?
Profiles can be manufactured in small PCB sizes or large industrial modules depending on requirements.
Do you provide prototypes and small batches?
Yes-we support sample runs and small batch production for testing before mass orders.
How do you ensure consistent quality?
Every batch undergoes dimensional inspection, coating checks, and thermal performance testing before shipment.
