Skived Fin heat sinks are the best alternative to extruded heat sinks when looking for a fin density which can’t be achieved by extrusion technology. Skived heat sinks can be manufactured from either copper or aluminum.  Today, skived heatsinks are breaking through the limitation of the thickness and length ratio of conventional heat sinks and our machines can produce high density and very high efficient heat sinks.  Super high and extreme thin fins and extra-long heat sink structure can be produced by our dedicated skiving machines using high skiving precision cutting technology.  Fin Skiving machines use a single block of material such as copper or aluminum and cut out fins with high density. The fins and the base is “one piece”. So skived fin heat sink efficiency is till two times higher than traditional heat sink.  Thermal conductivity efficiency can reach 100% of the profile material.

The Profimach/Pressmach hydraulic automatic Fin Crimping press for heat sinks is featured with open gap frame structure. These C frame presses and much bigger gantry presses are especially ideal for heat sink fin crimping or heat sink fin bonding and can handle a wide range of heatsink dimensions..

For customers from power electronic industry, who require accurate and repeatable processes for precision heat sinks, the Profimach/Pressmach upgraded C-frame presses are the ideal fin crimping press to choose. The press provides flexible precision control modes, which are “fixed speed/setting position stop”, “fixed speed/setting load stop”, “fixed speed/pressing distance stop”. The accuracy ranges in 0.01mm. A traveling table can also be offered for some special occasion, to offer the repeatable crimping cycle and the ability of automatically bonding/crimping of the fins in the heat sink.

Cold forging of Heat Sinks and Pin Fin Heat Sinks is a highly precise manufacturing process in which the workpiece is formed under high pressure and low temperature. The process ensures that no air bubbles, porosity or other impurities are trapped in the material, and thus produces products with exceptionally high quality.
