How to make aluminum alloy shell prototype

Generally speaking, the aluminum alloy prototype is one or several made according to the product appearance drawings or structural drawings without opening the mold, functional template used to check the appearance or structural rationality. The aluminum alloy prototype is also called the aluminum alloy first board in different places. The application scope of the aluminum alloy prototype is very wide, such as beer bottle opener, children's toys, kitchen utensils and bedroom locks. However, in most cases, many enterprises do more aluminum alloy shell prototypes, so how is the aluminum alloy shell prototype made? The following small series for you to analyze in detail.

In general, the production methods of aluminum alloy prototypes are CNC machining and 3d printing, however, at present, the case of 3d printing for aluminum alloy prototypes is relatively small, mainly because the cost of 3d printing is relatively high, so the production of aluminum alloy prototypes is mainly CNC processing. The prototype of this aluminum alloy shell in the following figure is processed by CNC. The surface treatment it uses is polished and sandblasted. Here are its main production steps:

CNC machining: the tool on the cnc equipment moves on the material according to the path set by the program, remove the excess part of the material, so as to get the prototype model.

polishing: since the prototype surface of the aluminum alloy shell processed by CNC has a rough edge and a knife mark, it needs to be smoothed with sandpaper.

sandblasting: spray a layer of particles on the prototype surface to reduce the roughness of the radiator prototype surface and make the prototype surface more exquisite.

when these surface treatments are finished, the prototype of the aluminum alloy shell is very exquisite. Therefore, when making the prototype of aluminum alloy shell, CNC machining is more appropriate, which is not only high in precision, but also low in cost.
