What are the common processing techniques of aluminum alloy parts?

- 2022-02-17-

Aluminum alloy is obtained by adding other metal elements to metal aluminum to obtain a metal alloy, such as silicon, iron, copper, aluminum, etc. The aluminum alloy obtained by adding other metals has the characteristics of low density, high strength, corrosion resistance, etc., aluminum alloy parts The machining process can separate roughing and finishing. After rough machining, the parts are heat treated to fully release the cutting stress and residual heat, and then finish machining, which will greatly improve the machining quality of the parts.

1.Machining of aluminum alloy parts

Also known as CNC machining, automatic lathe machining, CNC lathe machining, etc. If you are interested in precision machining, you may visit our machining parts in Aluminum Alloy Parts involving Precision Aluminum Alloy Die Casting Radiator. 

(1)Use general machine tools such as turning, milling, planing, drilling, and grinding to process mold parts, and then carry out necessary fitter repairs and assemble them into various abrasive tools. For examples, Sunbrihgt’s machining Aluminum alloy parts 

(2)For mold parts with high precision requirements, it is difficult to ensure high machining accuracy with ordinary machine tools, so precision machine tools are required for processing.

(3)In order to automate the processing of mold parts, especially punches with complex shapes, concave model holes and cavities, and reduce the workload of fitters, it is necessary to use CNC machine tools (such as three-coordinate CNC milling machines, machining centers, CNC grinding machines) and other equipment) to process mold parts. 

2.Stamping of aluminum alloy parts

Stamping is a forming and processing method in which a workpiece (stamping part) of the required shape and size is obtained by applying an external force to a sheet, strip, pipe and profile by means of a press and a die to cause plastic deformation or separation. Based on the power of conventional or special stamping equipment, the sheet metal is directly subjected to deformation force in the mold and deformed, so as to obtain the production technology of product parts with shape, size and performance. Sheet, mold and equipment are the three elements of stamping processing. Stamping is a metal cold deformation processing method, so it is called cold stamping or sheet stamping, or stamping for short. It is one of the main methods of metal plastic working.

3.Precision casting of aluminum alloy parts

Precision casting is a special casting. Parts obtained by this method generally do not require further machining. Such as investment casting, pressure casting, etc. The common practice is: first design and make a mold according to the product requirements (with very little or no margin), cast wax by casting, and obtain the original wax mold; repeat paint and sand on the wax mold Process, harden shell and drying; then melt the internal wax mold to dewax to obtain the cavity; bake the shell to obtain sufficient strength; pour the required metal materials, and remove the sand after shelling to obtain High-precision finished products, and then heat-treated and cold-worked according to product needs.

4.Powder metallurgy of aluminum alloy parts

Powder metallurgy is a technology of manufacturing metal powder, and using metal powder as raw material, through mixing, molding and sintering, manufacturing materials or products. It includes two parts:

(1)Manufacture of metal powder (also including alloy powder, hereinafter collectively referred to as "metal powder").

(2)Using metal powder (sometimes also adding a small amount of non-metallic powder) as raw material, after mixing, molding and sintering, manufacturing materials (called "powder metallurgy materials") or (called "powder metallurgy products")

5. Injection molding of aluminum alloy parts

The solid powder and the organic binder are uniformly kneaded, and after granulation, they are injected into the cavity of the mold with an injection molding machine in a heated and plasticized state (~150°C) to form, and then the formed blank is formed by chemical or thermal decomposition. The binder is removed in the final product by sintering and densification.
