 Product Description

Cast aluminum enclosures are made of aluminum alloy materials, generally including aluminum profile enclosures and aluminum die casting enclosures.


Cast aluminum enclosures are all kinds of enclosures made of aluminum alloys. Due to the convenience of processing, high flexibility, and high grades, they can effectively increase the added value of products and can be widely used in the electronics industry. They generally include aluminum profile enclosures and aluminum die-cast housings.


The aluminum profile enclosures is a enclosures processed on the aluminum profile obtained by aluminum stretching. It has high flexibility and can be cut at any depth. Generally, there are circuit board card slots inside, as long as the circuit board is directly inserted, no need to do it again Fixation and convenience are unmatched by other types of enclosures, but aluminum profiles are generally poorly waterproof and are not suitable for use in the wild and in harsh environments. So enclosures have wide application prospects.


The aluminum die casting enclosures adopts one-time die casting molding technology, which has the characteristics of waterproof and explosion-proof, and is suitable for field use.


Cast aluminum enclosures are widely used in various industries, and many industries or industrial productions need it to join. For example, it is used in many electronics and instruments, so what advantages does he have?


The aluminum alloy enclosures has a solid structure and beautiful appearance. It is very difficult for production needs to achieve both quality and aesthetics, but because the aluminum alloy chassis uses advanced production technology, and the materials it produces are quite good. Therefore, it is possible to produce a sturdy and beautiful product. In order to make it better applied to other production.;


What are the advantages of aluminum enclosures?

1.The elasticity coefficient is small, and the collision and friction cannot afford sparks, so it performs best in the automobile process.

2.There is no metal pollution, no toxicity, and no volatile metals on the surface oxide layer.

3.Compared with other metal materials, the density is small and the weight is light.

4.Strong plasticity, good productivity, has a very good advantage for production.

5.It adopts hot and cold processes, and has strong corrosion resistance.

6. Good casting performance.

7. The global aluminum content is very high and the reserves are rich.

8. It has very good ductility, and can be used to make light alloys with many metal elements, and the material is of high quality.

9. Good surface treatment performance.

10. The chemical properties are stable, non-magnetic, and can be recycled repeatedly. It is a benign and recyclable metal material.


The entire internal structure design of the cast aluminum alloy enclosure is very solid and firm, and it is very convenient to use. An aluminum bar is used in the lateral direction of the chassis to reinforce the entire chassis. All installations use tool-less installation. The pull-out hard disk rack used in the hard disk is very convenient to install. For ease of use, all audio and data interfaces are overhead.


The heat dissipation of the cast aluminum alloy enclosures; the heat dissipation design of the chassis has always been the strength of Cooler Master. The ultra-quiet 12CM fan is used in the front and rear, the front light-emitting fan, and the side panel adopts the air guide groove design, which provides a good heat dissipation environment for the chassis. At the same time, this chassis also reserves a water-cooled installation position, which is convenient for users to upgrade and use in the future.
