High performance geometries at high volume, low unit cost.
Cold forging produces pin-fin, elliptical and complex shaped heat sinks by forcing aluminium into a die at ambient temperature. The process gives excellent grain structure, tight tolerances and complete freedom over fin geometry — perfect for omnidirectional airflow.
The product range
A closer look at the materials we supply.
Cold forged aluminium pin fins for omnidirectional airflow and low pressure drop.
Bespoke base sizes and pin patterns formed straight from the tool to your specification.
Elliptical and shaped pins that extrusion or machining can't achieve.
Mounting bosses, standoffs and fixing points formed as part of the base for volume production.
Formed under pressure
Cold forging produces dense, fine-grained aluminium parts with excellent thermal conductivity.
Complex geometries
Round, elliptical and profiled pin fins that extrusion and machining can't achieve.
Omnidirectional airflow
Pin-fin arrays perform equally well from any airflow direction.
Tight tolerances
Repeatable, high-precision parts straight from the tool.
Volume-ready
The process shines at medium and high volume, driving unit cost down.
Integrated features
Mounting bosses, standoffs and fixing points formed as part of the base.
