Aluminum Extrusion & Aluminum machining part Introduction
Are you a DIY enthusiast and you work with various materials, especially aluminum? With this type of building material, you can achieve different shapes such as tube, flat and many more shapes. These various shapes are obtained from aluminum Extrusion & Aluminum machining part, a concept of mechanical manufacturing or creation.
This is the compression of a material which is forced to pass through a die with the shape of the part to be created. The result obtained is cleaner, more precise and does not require any modification.
Obtaining this perfect result no longer requires technicians to resort to machining parts. However, it is good to know that Aluminum Extrusion & Aluminum machining part can be used in other products. Such as:
- clay, but also pasta
This process is also found in the pharmaceutical field for the manufacture of medicaments such as pills.
What is Aluminum Extrusion & Aluminum machining part?
Aluminum Extrusion & Aluminum machining part is a process by which the metal, originally in billet form, is pushed under high pressure.
The extrusion of aluminum alloys can be done cold in the case of alloys with low mechanical strength and high ductility. Moreover, aluminum alloys are considered to be the most suitable materials for extrusion.
Similarly, they are distinguished by a variety of profiles unmatched compared to other materials.
Aluminum Extrusion & Aluminum machining part is a mechanical manufacturing process consisting in compressing a material into a given format under the action of pressure. Extrusion can be carried out hot or cold and can be combined with a chemical or enzymatic reaction.
Generally, in this case we speak of reactive extrusion. It produces long shapes, with a flat or hollow section. Subsequently, a very large number of materials can be extruded:
- textile fiber
- pulp ...
Aluminum Extrusion & Aluminum machining part: examples of applications
- Food industry:
Simple Aluminum Extrusion & Aluminum machining part is used to make pasta and some cookies. Cooking-extrusion combines mixing, shearing and compression operations which heat food, which produces “cooking” and evaporation of water.
This technique not only changes the structure and composition of foods, but also their functional and nutritional properties.
It is used for the manufacture of:
- breakfast cereals
- “cracotte” type pancakes
- infant flour
- aperitif snacks
- processed cheese
Extrusion cooking is also used for the texturing of proteins or the production of bioplastic by modification of thestarch.
The plastic is introduced into an extruder in the form of granules. The machine heats the granules which melt to give a homogeneous plastic paste. It will then be "blown" or molded through the extrusion head. We thus obtain products of different shapes:
- cans and
- PVC sheaths
- blinds ,
- pipes, plastic profiles , toys, signs ...
Aluminum Extrusion & Aluminum machining part makes it possible to obtain long pieces of metal with complex section shapes. Such as:
- aluminum profiles for automotive
- industry or construction
Given that obtaining long profiles with complex shapes with good mechanical resistance. They are in great demand by the market. It is done essentially by hot Aluminum Extrusion & Aluminum machining part. This process will be dealt with exclusively in what follows.
By the extrusion process, a long product is obtained with a constant cross section over its entire length. The section is generally more complex than that of a bar or tube. Depending on the shape of its cross section, it is called a solid, semi-hollow, or hollow profile.
Aluminum Extrusion & Aluminum machining part is a means of shaping which is not unique to aluminum. But this metal is the only one whose formability allows obtaining structural resistance profiles with very elaborate shapes that meet specific needs.
This is what makes extrusion very attractive to many processors. There are many functions that can be incorporated when designing a product made from extrusions.
Aluminum Extrusion & Aluminum machining part methods
There are two hot extrusion methods:
Direct Extrusion (Forward): The piston moves in the same direction as the extruded section, causing the billet to move relative to the container.
Indirect Extrusion (backward): The plunger is pushed against the billet in the opposite direction to that of the output of the profile. The billet remains stationary in the container.
Direct Aluminum Extrusion & Aluminum machining part is the simplest mode of production and can be done without lubrication. Likewise, direct extrusion makes it possible to confine the oxides initially present on the surface of the billet at the end of the profile.
And it aims to produce a product with a beautiful surface finish. Indirect extrusion, on the other hand, has the advantage of requiring a maximum load of 25 to 30% of that of direct extrusion of producing minimal heat and friction.
Parameters affecting the Aluminum Extrusion & Aluminum machining part process
Extrusion speeds and temperature
The temperature developed during aluminum Extrusion & Aluminum machining part has a great influence on the speed of the process. Especially in the case of aluminum alloys with high mechanical strength.
Aluminum alloy billets are generally heated between 350 and 500 ° C at the press entrance. During extrusion, the temperature of the material is affected by several factors. These phenomena occur simultaneously which explains the complex relationship that exists between the material to be extruded and the process parameters. Such as:
- billet temperature
- temperature and
- tool material
Problems and Troubleshooting with Aluminum Extrusion & Aluminum machining part
Possible causes: Too high extrusion speed, too much friction or too high temperature. At very low temperatures, the stick-slip phenomenon can cause cracks.
Causes: These defects occur under conditions of low friction and low extrusion rate. A large die angle, as well as a high ratio of height and strain zone length (h / L), can promote these defects.
Interior oxide bands
Causes: In homogeneity of the deformation causing the oxides present on the surface of the billet to drag towards the center.
Suggested solutions: reduce friction and temperature difference between the center and the periphery of the billet.
Aluminum Extrusion & Aluminum machining part and construction
The majority of construction companies now use this new system since it allows obtaining impeccable results. These professionals can have doors and windows made in different styles at the customer's request.
Resorting to the use of aluminum is the safest. Because it is an easy material to work and it does not weigh heavy. It should be noted that aluminum is a malleable metal that is very resistant to oxidation.
According to scientific studies, it is the metal that is found in abundance in the earth's crust after oxygen and silicon. With its silver color, it can be integrated anywhere and go well with all colors and other materials. T
The products obtained from the Aluminum machining part are also used in the manufacture of reinforcement for reinforced concrete and the various accessories that compose it.
Products obtained from aluminum
There are many things that can be made from aluminum extrusion other than building materials. Some car manufacturers use it for the manufacture of mechanical parts, bodywork, rims, roll bars, etc.
It is also used in making furniture home such as tables, cabinets, and also for the manufacture of stairs and various media. Of all the existing building materials, aluminum is the most widely used.
There are many reasons for this choice, such as its price which is very attractive. Moreover, it is very light weight, and its handling. Aluminum is very decorative and this is also the reason why some designers use it as a raw material today.
Where to find an Aluminum Extrusion & Aluminum machining part professional?
In recent years, several aluminum Extrusion & Aluminum machining part professionals have embarked on this field since it is a type of market that pays a lot. Similarly, aluminum is present everywhere and the risk of shortage is still very far away.
However, some of these manufacturers of objects obtained by extrusion boycott the quality of their achievements. The later only think about liquidating their product and no longer pay attention to the small details.
Finding a true professional can be easy, just look back on their accomplishments and years of experience in the field.
How aluminum extrusion products are manufactured?
Aluminum and aluminum alloy semi-finished products are produced by rolling or extrusion. Simultaneously, these are the two main shaping processes. Global consumption of semi-finished products is approximately 50% of total consumption. That of spun semi-finished products is around 25%.
