After we get the parts, we are often asked by customers for aluminum die-casting or aluminum extrusion. Sometimes we don't know whether an aluminum part should be die-casted or extruded. I don't understand the difference between these two kinds of processing. Today we will talk about the difference between die casting and extrusion. Click Here choose a best enclosure to check the extruded case and die-casting case in reality.

The processing of industrial aluminum profiles is common such as: assembly line aluminum, heat dissipation aluminum, etc. It adopts the extrusion molding process, that is, after the raw materials such as aluminum ingots are melted in the furnace, they are extruded through the extruder to the mold to flow out and formed. It can also extrude aluminum profiles of various cross-sections.

The processing appearance of industrial aluminum profiles is divided into bright and matte. The treatment process adopts anodizing treatment, and the surface treatment oxide film reaches a thickness of 0.12m/m.

The thickness of the aluminum profile processing wall is selected by the optimization of the product design. It is not the thicker the better in the market. It should be designed according to the requirements of the cross-sectional structure. It can vary from 0.5mm to 5mm. The layman's belief that thicker and tougher is actually a misconception.

The surface quality of aluminum profile processing also has defects that are difficult to overcome: warping, deformation, black lines, convex and concave and white lines.

Those with high level of designers and reasonable mold design and production process can avoid the above defects. The inspection of defects should be carried out according to the inspection methods stipulated by the state, that is, the visual distance is 40~50CM to determine the defects.

Although the processing of aluminum profiles has many advantages, it also has some disadvantages: the unoxidized aluminum is easy to "rust", which leads to a decline in performance, and its longitudinal strength is not comparable to that of iron products. The electroplating layer is easy to scratch. The cost is high, about 3 to 4 times higher than the cost of iron products.

Compared with the processing methods of die-casting aluminum alloys and aluminum profiles, the equipment used is different. Its raw materials are aluminum ingots (purity of about 92%) and alloy materials, which are melted in a furnace and entered into a die-casting machine for molding.

The shape of die-cast aluminum products can be designed like toys, with different shapes, which are convenient for connection in various directions. In addition, it has high hardness and strength, and can be mixed with zinc to form zinc-aluminum alloys. Die-cast aluminum products are cast in shape without sawing.
