Customer Case:

A European LED lighting manufacturer required custom Heat Sink Enclosure units to manage thermal output of high-power LED arrays. Previous suppliers delivered enclosures that warped under thermal stress.

We fabricated aluminum enclosures with TIG-welded reinforced frames and CNC-machined fins for maximum thermal dissipation. Electroless nickel plating provided grounding and corrosion protection.

The client reported improved thermal stability, reduced maintenance, and extended component lifespan. This solution has since become their standard for new high-power LED lines.
