What Are The Processing Techniques Of Aluminum Alloy Die Casting

What Are The Ways of Aluminum Alloy Die Casting Processing?

There are two ways to understand it: one is aluminum alloy processing and production. The die casting process is divided into four steps: casting, extrusion, straightening, surface treatment.

Secondly, what are the steps of aluminum alloy processing in the structural frame: the length of all aluminum alloy profiles on the market is 6.02 meters. When building different structural frames, it is necessary to cut the size of aluminum profiles. This process is also called processing, and there are other processing methods, such as drilling, through-hole, counterbore, tapping, cleaning grooves, and corner cutting.

Aluminum Alloy Processing

What are the processing technologies of aluminum alloy die casting?

1. Sand blasting 

The impact of high-speed sand flow is used to clean and coarsen the metal surface. This method of aluminum surface treatment can make the workpiece surface obtain certain cleanliness and different roughness, improve the mechanical properties of the workpiece surface, so as to improve the fatigue resistance of the workpiece, increase its adhesion with the coating, prolong the durability of the coating, and be conducive to the leveling and decoration of the coating. We often see aluminum alloy technology in various products of apple, which is increasingly adopted by the existing TV surface shell or middle frame.

2. Polishing

Using mechanical, chemical or electrochemical methods to reduce the surface roughness of automotive aluminum parts, so as to obtain a bright and flat surface. Polishing process is mainly divided into mechanical polishing, chemical polishing and electrolytic polishing. Automotive aluminum parts adopt mechanical polishing + electrolytic polishing, which can approach the effect of stainless steel mirror, giving people the feeling of high-grade, simple and fashionable future (of course, it is easy to leave fingerprints, so we should take more care).

3. Wire drawing

Metal wire drawing is a manufacturing process of repeatedly scraping aluminum plate with sandpaper. Wire drawing can be divided into straight wire drawing, random wire drawing, rotary wire drawing and thread drawing. Metal processing wechat has good content and deserves attention. The metal wire drawing process can clearly show every fine silk mark, so that the fine hair luster can be emitted in the metal matte. The product is fashionable and scientific.

4. High gloss cutting

The engraving machine is used to reinforce the diamond knife and cut parts on the main shaft of the engraving machine with high-speed rotation (generally 20000 RPM), resulting in local bright areas on the product surface. The brightness of cutting highlight is affected by the speed of milling bit. The faster the drill speed is, the brighter the cutting highlight is. Otherwise, the darker it is, and it is easy to produce knife marks. Metal processing wechat has good content and deserves attention.

5. Anodizing

Anodic oxidation refers to the electrochemical oxidation of metals or alloys. The process of forming oxide film on aluminum products (anode) by aluminum and its alloys under corresponding electrolyte and specific process conditions. Anodizing can not only solve the defects of aluminum surface hardness and wear resistance, but also prolong the service life of aluminum and enhance its beauty. It has become an indispensable part of aluminum surface treatment. It is the most widely used and successful process at present.
