Processing method of aluminum stamping parts

Processing method of aluminum stamping parts

1. Extrusion:

The molten aluminum in molten state is poured into the mold, and it is injected into the mold under high pressure by a die-casting machine.

2. Pultrusion:

The sheet metal is deformed in the mold by hydraulic or mechanical methods.

3. Casting and pressure casting:

Using gravity or other external force to pour the liquid alloy into the mold to solidify and form is called casting; the use of air pressure, high pressure gas or electric arc and other energy sources for pressure processing to obtain the required shape and size of parts is called pressure casting.

4. Powder metallurgy method:

A new process method for directly adding powdered metal to liquid alloys for forming.

5. Spinning forming:

Compressed air is used as the power to apply external force to the rotating blank to produce axial compression and at the same time complete the plastic flow on the cross section.

6. Roll forming:

Through heating and rolling, the carbides in the billet are distributed in a solid state, thereby improving the hardness and strength of the material.

7. Forging and free forging:

A processing method in which a hot ingot is placed on an anvil and subjected to repeated impact or pressure.
A machining process in which the material is plastically deformed by the force of the punches rotating in opposite directions simultaneously acting on the workpiece to be machined.

8. Welding:

• (1) After the two steel plates are butted, they are lapped together to form a whole;
• (2) Weld the two steel plates together to form a combined structure;
• (3) A connection structure of connecting and welding several steel plates into a large workpiece;
• (4) There are several forms of welding between points and points.

Stamping parts processing plants often encounter customers who need aluminum stamping parts. Since the weight of aluminum materials is relatively light, the net weight of products of the same size is also relatively light, and the cost will be reasonably reduced. Generally speaking, the surface of aluminum stamping parts is prone to various problems, and customers will require surface treatment of the stamping parts after production. So what are the surface treatment methods for aluminum stamping parts?

1. Metal wire drawing treatment

There are thousands of types of metal drawing for aluminum stamping parts, the more common ones are straight metal drawing, textured metal drawing, spiral metal drawing, and external thread metal drawing. The aluminum stamping parts after metal drawing can be seen to have clear tiny imprints on the surface, and the product has a feeling of shiny silk patterns in the visual effect. Most of the aluminum stamping parts need surface treatment after production and processing, but the actual treatment method used depends on the actual regulations of the customer.

2. Aluminum anodic oxidation reaction

The surface solution of the improved aluminum stamping parts is forced to mention the processing technology of anodizing oxygen reaction. Anodizing oxygen reflection can reasonably make up for the lack of surface strength and wear resistance of aluminum stamping parts, and can also greatly increase the service life of aluminum stamping parts and make the product look good. Today, the anodizing oxygen reaction has already become a more common and widely used surface treatment method for aluminum stamping products. The anodic oxidation oxygen reaction refers to the photoelectric catalytic oxygen reaction of metal materials or aluminum alloys. Aluminum and aluminum alloys are under the relative lithium battery electrolyte and special processing technology standards, because of the effect of additional current, in metal aluminum (anode anode). Oxidation) to produce a layer of oxygen reflecting the whole process of the film.

In addition, aluminum stamping parts can also obtain surfaces of various colors according to the reaction of anodized oxygen, which further expands the application places of aluminum stamping parts.

3. Sandblasting

Sand blasting is generally an intermediate process for the surface solution of aluminum stamping parts. The aluminum stamping parts after sand blasting can reasonably remove the burrs and oil stains on the surface. Surface roughness of the product. After sandblasting, the characteristics of the product can be significantly improved. In the subsequent surface treatment, the adhesion between the aluminum stamping part and the coating can also be expanded, which makes the product durable and beautiful.

4. Grinding and polishing

The polished aluminum stamping parts can be close to the actual effect of mirror glass, which greatly improves the level of the product and the level of beauty. However, due to the characteristics of metal aluminum, the grinding and polishing of aluminum stamping parts is relatively rare, and if no other surface treatment is done after grinding and polishing, the wear resistance will be relatively low. After grinding and polishing of aluminum stamping parts, it is difficult to maintain the actual effect of mirror glass for a long time. Generally, products that require the actual effect of mirror glass are recommended to use stainless steel plate.
