Ionthis Extrusions and Heat Sinks, Heat Pipes, Enclosures and Components

Ionthis manufactures Extruded Aluminum Heatsink, Aluminum Extrusions, and Heat Sinks, and Heat Pipes, including Aluminum Extruded Enclosures, Housing and components, and  multitudes of Mechanical Heat Dissipating Components, including: :

  1. Traditional Extruded Heat Sinks from aluminum heatsink extrusion profiles.
  2. Heat Pipe: utilizes a sealed copper tube to transfer heat from a source to a traditional heat sink.
  3. Liquid Cooled Heat Pipes: utilizes copper tubes to flow liquid through a plate our an extruded heat sink for additional cooling.
  4. Spreader Bars / Cold Plates Heat Sink: utilizes solid copper bars are plate inserted into an aluminum plate or heat sink to move heat rapidly away from the heat source.
  5. Folded Fin Heat Sink: Utilizes thin copper folded sheet metal and soldered on a plate.
  6. Bonded Fined Heat sinks: uses a thin aluminum or copper cut plate that is boned perpendicular to a think plate allowing the fins to be flat, taller, and closer together than a traditional Extruded Heat Sink.
  7. Skived Heat Sinks Made from a Skive Machine shaving thin fins off a plate.
  8. Stamped Sheet Meat Heat Sinks; economical stamped from sheet metal.
  9. Extruded Enclosures, Housings, and other Custom OEM Components.

We specialize in finished components. We are capable of extruding the smallest cross-sections up to 30″. This means we only extrude the material that meets the quantity requirements, not force-feed our customers’ hundreds of feet they cannot use.

We also finish the part including Machining, Welding, Anodizing, Plating, Powder Coating, Silk Screen, and much more, as shown below. By providing full service, contract manufacturing, our customers’ complete control of their quality from a single source. For more information about the Extrusion Process and more details on the other heat sinks above, please see our section “Extrusion and Heat Sink Process” under MFG Processes explained.

  4. GTAW and GMAW Welding as well as soldering
  5. Thermal Pad and Past installation including robotic EMI application on extrusions and heat sinks

We are a “one-stop-shop “ for extrusions and heat sinks. This eliminates resending out your extrusions and heat sinks for a secondary process to separate multiple vendors. The significant advantage to this is our extrusions, and heat sinks customers now only have one source responsible for your quality and on-time delivery needs.

"Cradle To Grave" Contract Manfacturer

“Cradle to Grave” means as your extrusions and heat sinks mature, we will continually give you suggestions (process changes, material changes, sub-assemblies) to reduce your cost giving you an improved sales advantage. An example would be perhaps at the beginning of marketing your product, and your volumes are low. Since Ionthis is a component manufacture, we can produce low volumes. Typically extruders want customers to buy thousands of feet of the extruded bar even when the customer only needs 100 sets.

Ionthis is set up to meet the customer requirement on extrusions and heat sinks and will run only one or two Randoms with a lower cost; low volume dies to meet our customer’s smaller quantity requirements. When our customer volumes become high enough to justify a high production die or other processes to reduce the part cost, then Ionthis will recommend moving a high production mold or other processes to REDUCE COST. This is “Cradle to Grave.”
