DECALUMA is a professional manufacturer of the heat sink skiving machine, with more than 10 years’ experience of professional fin skiving machine manufacturing. Till now, we have sold more than 300 professional skiving machines to China domestic and overseas customers. Our fin skiving machines have 5 different series, covering heat sinks as small as 5mm wide and large heat sinks with width of 600mm and length of 1600mm.
OUR FIN SKIVING MACHINES CAN SKIVE FINS FROM 50UM TILL 3MM THICKNESS
We have a variety of skiving machine models for different copper or aluminum heat sink/radiators, and the width of the fins can reach a maximum of 600mm. 
Our machine can realize precision processing and convenient operation, which is very different from hydraulic machines. It skiving machine is a revolutionary audit product in the industry.
We are the developer and manufacturer of CNC FIN SKIVING MACHINE. We provide pre-sales machine’s model- selection, after-sales installation & training, provide timely technical support to global customers, and provide “Turnkey” engineering services.

SKIVED FIN HEAT SINKS FEATURES & ADVANTAGES

THE SKIVED FIN,ALSO KNOWN AS SKIVING TECHNOLOGY,
SIMPLY TAKES AN ENTIRE PIECE OF ALUMINUM OR COPPER AND USE SPECIAL SKIVED MACHINE 
TO CUT OUT FINES WITH STANDARD SPACING AND A CERTAIN THICKNESS AND HEIGHT.
Because of using high precision cutting technology, the integration of the forming, relative to other processing technology, the same volume of raw materials can be cut out more heat dissipation area, the heat transfer performance is more stable, in the same condition,the cooling performance is more than 1.5~2 times of the efficiency of traditional bonded fin or soldering heat sink, thus greatly improve heat dissipation efficiency and extend the service life of heating components.
SKIVED HEAT SINKS CAN BE CONSTRUCTED OF ALUMINIUM 
OR COPPER ALLOWING FOR FULL, ONE-SINGLE-PIECE SOLUTIONS WITHOUT THERMAL 
BARRIERS FOR HIGH PERFORMANCE COOLING.
Skived Fin Heat Sinks offer highly optimized cooling as they allow for higher fin densities than what is manufacturable using extrusion methodologies, but do not have an interface joint that restricts heat flow like bonded or brazed fin heat sinks. Unlike bonded or brazed heat sinks, Skived Fin Heat Sinks are constructed from a single piece of material and offer reduced thermal resistance since there is no joint between a base and fins. These heat sinks are manufactured by precisely slicing the top of the base, called skiving, folding it back to where it is perpendicular to the base, and repeating at regular intervals to create fins.
The skiving process enables high fin density and thin fin heat sink geometries for optimal thermal performance. By packing as much fin surface area into a given volume, skived fin heat sinks have greater heat transfer than other single piece construction heat sinks such as extruded aluminum heat sinks. Compared to extruded aluminum, skived fin heat sink fabrication does not rely on expensive tooling, providing greater design flexibility and faster prototyping. Instead, each fin is cut separately using the same tool which allows for lower tooling costs. 

SKIVED FIN HEAT SINK HAS THE FOLLOWING ADVANTAGES

(1) Perfect conductivity between base and fins. Because skived fin heat sink is a whole profile without any connection point, which can give full play to the heat dissipation characteristics of the heat sink.
 (2) High fin densitie, Lori's skived fin process can make the skived fin more thinner and denser, with higher heat transfer efficiency. 
(3) Great forced airflow solution, the skived fin processing technology is simpler than other liquid cooled heat sink, with lighter weight and lower cost.
 (4) Compared with aluminum extrusion and other processes, skived heatsink is less limited in size and can be made wider, which can be used for heat transfer of machines with large power.
 (5) Customized skived fin heat sink does not need expensive tooling which provides greater design flexibility. Instead, each skived fin is cut separately using the same tool which allows for lower tooling costs.
 (6) Add a thermal interface material to the skvied fin heatsinks to better connect with your heat source and complete your thermal solution.

SKIVED FIN HEAT SINKS INDUSTRIES APPLICATIONS

TECHNICAL INFORMATION

  • Heat sinks are used to maintain the temperature of a component or a system by providing a series of extended surfaces called fins. There are a lot of heat sinks that are produced with skiving available in the market. These types of heat sinks consist of uniformly shaped and closely spaced fins. Thes
  • · Extruded Heat SinksThe majority of heat sinks are made from extruded aluminum. The process is useful for most applications. Extruded heat sinks come at a low cost and custom specifications can be easily manufactured. · Bonded Heat SinksThese are normally used for applications that require large-si
  • Diodes, transistors, and integrated circuits generate considerable amounts of heat during operation. Extreme heat can damage or significantly affect the performance of semiconductor devices, and therefore, supplemental cooling is necessary to maintain the temperature within the limits specified by a
