Aluminum profile shells have their own advantages compared with aluminum die-cast shells. Aluminum alloy shells are various shells made of aluminum alloy. Due to their easy processing, high flexibility and high grade, they can effectively increase the added value of the product and are able to It is widely used in the electronics industry and generally includes aluminum profile casings and aluminum die-cast casings.
(1)Aluminum profile shell
The aluminum profile shell is a shell processed from an aluminum profile obtained by drawing aluminum. It is highly flexible and can be cut to any depth. Generally, there is a circuit board slot inside. You only need to insert the circuit board directly, no need to The fixation and convenience are unmatched by other types of shells. However, aluminum profile shells generally have poor waterproofing and are not suitable for use in the wild and harsh environments. Cixi Zhengsheng Shell Co., Ltd. has the most complete range of such products. This type of housing has a wide range of application prospects.
Scope of application: car computers, power amplifiers, receivers, instrumentation, radio frequency, laser lights, inverters, rectifiers, electronic components, shielding boxes, controllers, transmitters, headphone amplifiers, PCB circuit boards, radios, GPS, mobile power supplies , communications, etc.
Aluminum profile mold process characteristics: Aluminum profiles are very complex, especially ultra-high-precision thin-walled hollow profiles and porous hollow wall panel profiles, which require a special mold structure. Often, multiple special-shaped cavities are opened on one mold at the same time. The thickness of the cross-section changes rapidly, the related dimensions are complex, and there are many arc corners, which brings a lot of trouble to the processing and heat treatment of the mold.
The processing technology of extrusion molds is different from the general mechanical manufacturing process. It is a special technology that is very difficult and covers a wide range of areas. In order to produce high-quality and long-life molds, in addition to selecting high-quality materials, it is also necessary to Have reasonable processing technology.
(2) Aluminum die-cast shell
The aluminum die-cast shell adopts one-time die-casting technology, which is waterproof and explosion-proof and suitable for outdoor use. However, it is more expensive and has low flexibility. Size changes can only be achieved by modifying the mold.
Scope of application: home appliances, medical care, instruments, automobiles, electronics, radar, television, aerospace, hardware, daily necessities, etc.
Characteristics of the aluminum die-casting mold process: The aluminum die-casting mold is quickly filled into the cavity of the die-casting mold under certain conditions under high pressure, and is rapidly cooled under a certain pressure. The die-casting process is a process of organic combination and application of the three die-casting production factors of die-casting alloy die-casting mold machine.
Aluminum die-casting molds have the advantages of high precision, low surface roughness and high material utilization. Not only can they manufacture metal parts with complex shapes, clear outlines, thin walls and deep cavities, but they can also directly cast parts of other materials on the die-casting parts. to help save valuable materials and processing. Therefore, die castings have a dense structure, high strength and hardness, and extremely high productivity. However, die-casting parts often have pores and oxidized inclusions, which are not suitable for small batch production. The size of die-casting parts is limited, and the types of die-casting alloys are restricted.
