Extrusão de Alumínio e a peça de usinagem de Alumínio 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.

É a compressão de um material que é forçado a passar por uma matriz com a forma da peça a ser criada. O resultado obtido é mais limpo, preciso e não requer modificações.

A obtenção desse resultado perfeito não exige mais que os técnicos recorram à usinagem de peças. No entanto, é bom saber que a Extrusão de Alumínio e a peça de usinagem de Alumínio  podem ser utilizadas em outros produtos. Tal como:

  • Metais
  • Plásticos
  • Compósitos
  • argila, mas também macarrão

Este processo também é encontrado no campo farmacêutico para a fabricação de medicamentos, como pílulas.

O que é Extrusão de Alumínio e Parte de usinagem de Alumínio?

Extrusão de Alumínio e a peça de usinagem de Alumínio  é um processo pelo qual o metal, originalmente na forma de tarugo, é empurrado sob alta pressão.

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.

Extrusão de Alumínio e a peça de usinagem de Alumínio 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:

  • Metal
  • Plastic
  • rubber
  • ceramics
  • textile fiber
  • pulp ...

Extrusão de Alumínio e a peça de usinagem de Alumínio: examples of applications

  • Food industry:

Simple Extrusão de Alumínio e a peça de usinagem de Alumínio 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
  • confectionery
  • “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.

  • Plastics:

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:

  • Cups
  • cans and
  • containers
  • cables
  • PVC sheaths
  • blinds ,
  • pipes, plastic profiles , toys, signs ...

Metallurgy:

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 Extrusão de Alumínio e a peça de usinagem de Alumínio. 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.

Extrusão de Alumínio e a peça de usinagem de Alumínio 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.

Extrusão de Alumínio e a peça de usinagem de Alumínio 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 Extrusão de Alumínio e a peça de usinagem de Alumínio 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 Extrusão de Alumínio e a peça de usinagem de Alumínio processo

 

Extrusion speeds and temperature

A temperatura desenvolvida durante a extrusão e usinagem de alumínio  tem uma grande influência na velocidade do processo. Principalmente no caso de ligas de alumínio com alta resistência mecânica.

Os tarugos de liga de alumínio são geralmente aquecidos entre 350 e 500 ° C na entrada da prensa. Durante a extrusão, a temperatura do material é afetada por vários fatores. Esses fenômenos ocorrem simultaneamente, o que explica a relação complexa que existe entre o material a ser extrudado e os parâmetros do processo. Tal como:

  • temperatura do tarugo
  • atrito
  • temperatura e
  • material de ferramenta

Problemas e solução de problemas com Extrusão de Alumínio e a peça de usinagem de Alumínio

Rachaduras superficiais

Possible causes: Too high extrusion speed, too much friction or too high temperature. At very low temperatures, the stick-slip phenomenon can cause cracks.

 Interior 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?

Os produtos semiacabados de alumínio e ligas de alumínio são produzidos por laminação ou extrusão. Simultaneamente, esses são os dois principais processos de modelagem. O consumo global de produtos semiacabados é de aproximadamente 50% do consumo total. O dos produtos semiacabados fiados gira em torno de 25%.
