aluminum alloy castingAluminum is one of the most widely used non-ferrous metals, and its scope of application is still expanding. Aluminum production of a wide range of aluminum alloy parts. According to statistics, aluminum alloy components haveMore than 700,000 kinds, from the building decoration industry to the transportation industry, the aerospace industry have different needs. below to introducealuminum alloy castingWhat is the craft?

aluminum alloy castingStamping:

1. Cold stamping.

An aluminum particulate material was used. The extruder and the mold are suitable for cylindrical aluminum alloy parts or product shapes that are difficult to obtain by the drawing process, such as oval, square, and rectangular aluminum alloy parts.

The tonnage of the machine used is related to the cross-sectional area of the aluminum alloy part. The gap between the upper punch and the lower tungsten steel is the wall thickness of the product, and the vertical gap between the upper punch and the lower tungsten steel to the bottom dead center is the top thickness of the product.

Advantages: short open mold cycle, the development cost is lower than the wire drawing die.

Disadvantages: the production process is long, the size of aluminum alloy parts fluctuates greatly in the process, and the labor cost is high.

2. Stretching.

Aluminum housing. Applicable to non-columnar bodies(Aluminum alloy parts with bent aluminum) Many times use continuous die cutting machines and molds to meet the shape requirements.

Advantages: In the production process, the complex miscellaneous deformed aluminum alloy parts have stable size control and smooth product surface.

Disadvantages: high mold cost, long development cycle, high precision machine selection.

aluminum alloy castingSurface treatment:

1. Sand blasting (shot peening)

The process of cleaning and roughening metal surfaces by the impact of a high-speed sand stream.

In this way, the surface of aluminum alloy parts can be treated with certain cleanliness and different roughness to improve the mechanical properties of the parts, thereby improving the fatigue resistance of the aluminum alloy parts, increasing the adhesion between the parts and the coating, and extending the coating Durability is conducive to the leveling and decoration of the coating.

2. Grinding.

aluminum alloy castingThe surface roughness of aluminum alloy parts is reduced by mechanical, chemical or electrochemical action to obtain a bright and smooth surface.aluminum alloy castingThe polishing process is mainly divided into mechanical polishing, chemical polishing and electrolytic polishing. After mechanical polishing and electrolytic polishing, the aluminum alloy parts can approach the mirror effect of stainless steel.

What we should pay attention to is that inaluminum alloy castingCenter machining parts are the result of the overall process system and processing environment. The source of error is very complex, and the machining accuracy of parts depends on various factors of the system. Therefore, it is necessary to comprehensively consider all aspects, analyze and find out the error sources that affect the accuracy of parts, so as to take corresponding measures.

I believe that through the above introduction, everyone is interested inaluminum alloy castingThere is also a lot of understanding.aluminum alloy castingIt has brought a lot of convenience to our industry, allowing us to process parts faster and with better quality. We arealuminum alloy castingThe manufacturer has many years of experience in this industry.
