aluminium extrusion mold for swing door front frame

Wire Electrical Discharge Machining

It belongs to the category of electric processing.

When the couple of the former Soviet Union Lazalianke studied the phenomenon and cause of the damage of the switch contacts by spark discharge corrosion, they found that the instantaneous high temperature of the electric spark can make the local metal melt, oxidize and be corroded, thus creating And invented the electric discharge machining method.

The wire cutting machine was also invented in the former Soviet Union in 1960, and our country was the first country to use it in industrial production.

EDM wire cutting machine can be divided into reciprocating type:

High Speed Wire cut Electrical Discharge Machining

Low Speed one-way walk Wire cut Electrical Discharge Machining

Vertical Wire Electrical Discharge Machining machine tool With Rotation Wire.

It can also be divided into single column cross table type and double column type (commonly known as gantry type) according to the form of workbench.

Aluminium Extrusion Working Principle:

During extrusion, under the strong extrusion force, the ingot is divided into several strands of metal by the knife (bridge part) of the mold and flows into the mold welding chamber. Under the conditions of high temperature, high pressure and high vacuum, the metal is re-welded and flows from the die hole to the needle. It flows out from the formed gap to form a hollow product of the required shape and size. The number of welds in the product is the same as the number of strands of metal flow.

Application of aluminum alloys in aerospace

The aerospace industry is an important high-tech field and has extremely high performance requirements for materials. In the complex space environment, spacecraft need to face challenges such as extreme temperature changes, strong radiation, and vacuum environments. Therefore, the materials selected must have excellent mechanical properties, physical properties, and chemical properties. Aluminum alloy has been widely used in the aerospace industry due to its own advantages.

1. Low density: The density of aluminum alloy is much lower than that of iron, steel and other materials, but its strength is very high. In the manufacturing of spacecraft, especially the shell, frame and other parts of the spacecraft, aluminum alloy materials are often used to reduce the weight of the spacecraft.

3.Corrosion resistance: In the complex space environment, aluminum alloy has good corrosion resistance and can ensure the normal operation of the spacecraft.

4. Processing performance: Aluminum alloy has good processing performance and can be made into parts of various shapes through various processing methods to meet the needs of the aerospace industry.

5. Electrical conductivity: Aluminum alloy has excellent electrical conductivity and can be used in the electrical system of spacecraft.

6. Has good welding performance: Aluminum alloys can be connected through various welding methods to meet the structural design needs of spacecraft.
