Aluminum alloy has the characteristics of low density, high strength, corrosion resistance, etc. Its portability and strength make aluminum alloy widely used in the processing and manufacturing of various parts. What are the five common methods for processing aluminum alloy accessories?
Processing of aluminum alloy parts
1、 Five methods for processing aluminum alloy accessories:
1. Stamping of aluminum alloy parts
Stamping refers to the forming and processing method of workpieces that can produce plastic deformation or separation by exerting external force on plates, strips, pipes and profiles through presses and dies according to the shape and size of the required workpieces.
2. Machining of aluminum alloy parts
It mainly uses general machine tools such as vehicle, milling, planing, drilling and grinding to process mold parts and assemble them into various molds. Machining of aluminum alloy parts can also be called CNC precision machining or automatic lathe machining, CNC lathe machining, etc.
3. Precision casting of aluminum alloy parts
Parts obtained by this method generally do not need to be machined. The shape and casting precision of precision casting are higher than those of traditional processing methods.
4. Powder metallurgy of aluminum alloy parts
Powder metallurgy is a technology that uses metal powders as raw materials to produce materials or products through mixing, molding and sintering.
5. Injection molding of aluminum alloy parts
The solid powder and organic binder are uniformly mixed, granulated, heated and plasticized, and then injected into the mold cavity with an injection molding machine for curing and molding. The binder in the preform is removed by chemical or thermal decomposition methods, and the final product is obtained by sintering and densification.

2、 Three characteristics of aluminum alloy parts processing:
The aluminum profile processing process includes three whole processes: melting, extrusion and coloring (coloring key includes: oxidation, electrophoresis process, fluorocarbon painting, electrostatic powder spraying, wood grain transfer printing, etc.). Processing characteristics of aluminum alloy parts:
1. Low processing hardness of aluminum alloy
Compared with titanium alloy and quenched steel, aluminum alloy has lower hardness. Of course, heat treated or die cast aluminum alloy also has higher hardness. Generally, the HRC hardness of aluminum plate is below HRC40. Therefore, in the case of aluminum alloy processing, the tool load is small. In addition, aluminum alloy has excellent thermal conductivity, so the cutting temperature of aluminum alloy milling is low, which can improve the milling speed.
2. Low plasticity in aluminum alloy processing
Aluminum alloy has low plasticity and low melting point. When processing aluminum alloy, the bonding edge problem is very deep, the chip removal performance is poor, and the surface roughness is also high. In fact, the main reason for processing aluminum alloy is that the effect of knife and roughness is not good. If the two problems of fixed blade and quality of machined surface are solved, the problem of aluminum alloy machining can be solved.
3. Aluminum alloy processing tools are easy to wear
Due to the use of unsuitable tool materials, when processing aluminum alloys, tool wear is accelerated due to problems such as rod edge and chip discharge.
Aluminum alloy CNC processing manufacturer
Xiao Bian believes that you have a certain understanding of the aluminum profile processing process and aluminum alloy processing characteristics. In addition, if we choose aluminum alloy CNC processing manufacturers, we must choose qualified CNC processing manufacturers to have a good CNC processing service experience.
