Extrusion Profiles

Extrusions are a method of making heat sinks that is cost effective. The metal is forced through a die producing an extrusion profile (Tooling required). The result is bar stock extrusions that can be cut to the required length of the heat sink. Most heat sink profiles can be made into an extrusion profile. We offer short lead time and inexpensive tooling.
