Pressure Die Casting Aluminum Heat Sinks Die Castings vs Extrusions. There are different ways to create molded metals. One of the old methods is sand casting. This is still used at present and is useful in creating large metal custom made pieces. While this is convenient and perhaps quite inexpensive, it does not compare to the quality of more modern processes. Of course, it creates a rough metal part.
A more smoothed poured aluminum fixture would be created through gravity casting. But the more modern methods are Pressure Die Casting Aluminum Heat Sinks Die Castings vs Extrusions.
Pressure die casting uses modern technology like pressurized chambers to force melted metals like aluminum to mold into different complicated fixtures. These are then used for vehicles, industrial machines and household appliances.
Through extrusions, aluminum heat sinks are also casted. A die is used – a deep block serving as the mold. The preheated metal is then forced into this die to form individual or continuous pieces. This will of course only work for repetitive designs. A hydraulic powered press is used to push the metal into the die. Like die casting, it is possible to make a lot of quality parts with only one die or mold.
However, extrusions do not bring much flexibility when it comes to design. The die block is somewhat of a limitation for more fluid designs for pieces like sinks.

Removing Heat in a Cheaper and Faster Way. Heat sinks are important in electronic applications or products because they absorb the heat to avoid overheat and malfunction. These aluminum heat sinks are designed in such a way that the heat coming from the electrical wires and other parts that are prone to heat production will be diverted to them. Since heatsinks are very important in many electronic products, manufacturers are designing cheaper and faster ways to produce them. One of the popular materials used in heat sinks is aluminum and these heat sinks are dicasted.
Aluminum is a strong metal that is perfect in making heat sinks. It is also easy to mold but very durable and can withstand high temperatures. The abundance of aluminum also makes it possible to produce cheaper products as compared to other metals. Die-casting is one of the best ways to make heat sinks. With diecasting, detailed heat sinks are produced in a short period of time, thus mass production is possible. Once heat sinks are produced, they are just mounted on the printed circuit board or the PC board of the electronic products. With this, the diversion of heat is now possible so as to prevent malfunction and can lead to longer lifespan of the application.
Where do you find Aluminum Heat Sinks Die Castings. Aluminum is a tough and durable metal. It is as durable as steel in some cases. The aluminum metal is lightweight, weighing only one third the weight of a steel bar of the same size and shape. It is electrically conductive. Aluminum is also heavily abundant, making it very easy and cheap to acquire. This makes aluminum most ideal for making heat sinks die castings.
Aluminum heatsinks die castings are mainly used to regulate, ingest and disperse the heat generated by machines, engines, products by direct thermal contact. Aluminum heat sinks and die casts are used by plenty of manufacturers due to its efficient heat dissipation approach processes. Aluminum heat sinks provide hydraulic qualities to cool different areas and parts of a particular engine or machine. They also protect the devices from exposure to high temperatures.
Aluminum heat sinks die castings can be found in many major industries, namely:
- In airplane industries, for airplane parts and machines
- In electronic industries, for computer parts, electronic apparatus, and their printed circuit boards
- In communication industries for microwave, satellite, cellular components
- In automotive industries, for motors, oils and electronics
- In lighting industries, for fixtures, lightings, housings, lasers
Extruded aluminum heatsinks are made by heating aluminum to the point of a semi-solid state. Then this aluminum is pushed (extruded) through an extrusion die. These aluminum forms have the profile of the die it was pushed through, much like the play dough toy extruder. The simple shapes are stars or circles. These forms are cut to the length needed.
Aluminum Heatsinks that are extruded typically have a flat bottom and ribs on the top. They can be extruded in lengths of several feet an cut to shorter lengths. Because these extruded aluminum heatsinks were formed by pushing through a die, there is a limitation on details that can be formed on the top and bottom surfaces. If a depression is needed to mount components then it will need to be machined into the part as a pocket as an after operation, dramatically increasing the part cost. More typically, if holes are needed for mounting, they too will need to be machined into the parts as a secondary operation. Any other holes needed so wires or components can pass through have the same limitation.
The Aluminum Die Casting Process injects metal into a mold or die that forms the top, bottom and sides. Mounting holes, through holes and cavity indentations formed into the part are in the die halfs on the top and bottom. Aluminum Die Casting Heatsinks will have all the features necessary for installing the components and the holes for mounting during the original manufacturing operation. Die casting heatsinks will not require secondary operations for holes and features.
