Problems and Troubleshooting with Aluminum Extrusion & Aluminum machining parts

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:

• Metals
• Plastics
• Composites
• 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:

• Metal
• Plastic
• rubber
• ceramics
• 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
• 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:

aluminium extrusie- en aluminiumbewerkingsonderdeel 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
• friction
• temperature and
• tool material

Problems and Troubleshooting with Aluminum Extrusion & Aluminum machining part

Superficial cracks

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

De meeste bouwbedrijven gebruiken dit nieuwe systeem nu omdat het onberispelijke resultaten oplevert. Deze professionals kunnen op verzoek van de klant deuren en ramen laten maken in verschillende stijlen.

Het gebruik van aluminium is het veiligst. Omdat het een gemakkelijk te bewerken materiaal is en niet zwaar weegt. Opgemerkt moet worden dat aluminium een ​​vervormbaar metaal is dat zeer goed bestand is tegen oxidatie.

Volgens wetenschappelijke studies is het het metaal dat na zuurstof en silicium in overvloed in de aardkorst wordt aangetroffen. Met zijn zilveren kleur kan hij overal worden geïntegreerd en past hij goed bij alle kleuren en andere materialen. T

De producten verkregen uit het aluminium bewerkingsonderdeel worden ook gebruikt bij de vervaardiging van wapening voor gewapend beton en de verschillende accessoires waaruit het bestaat.

Producten verkregen uit aluminium

Er zijn veel dingen die gemaakt kunnen worden van aluminium extrusie anders dan bouwmaterialen. Sommige autofabrikanten gebruiken het voor de fabricage van mechanische onderdelen, carrosserieën, velgen, rolbeugels enz.

Het wordt ook gebruikt bij het maken van meubels zoals tafels, kasten, maar ook voor de vervaardiging van trappen en verschillende media. Van alle bestaande bouwmaterialen wordt aluminium het meest gebruikt.

Er zijn veel redenen voor deze keuze, zoals de prijs die erg aantrekkelijk is. Bovendien is het erg licht van gewicht, en de bediening ervan. Aluminium is erg decoratief en dit is ook de reden waarom sommige ontwerpers het tegenwoordig als grondstof gebruiken.
