Aluminum Extrusion: The Ultimate Guide

The aluminum extrusion process is to put the aluminum ingot into the extrusion cylinder, apply pressure to the aluminum through the extrusion shaft, and make it extrude from the die hole with a given shape and size, and produce plastic deformation to obtain the required extrusion. A processing method for pressed products.

Aluminum profile extrusion process and working principle?

Aluminum profile extrusion is a plastic processing method that applies external force to the aluminum ingot contained in the extrusion cylinder to make it flow out of a specific die hole, so as to obtain the required cross-sectional shape and size. The figure below shows the aluminum profile extrusion Schematic diagram of press forming;

aluminum extrusion die

For product structure design engineers, although we do not design aluminum extrusion dies, understanding the most basic extrusion die structure and the mechanism of how to shape different extrusion shapes will help in extrusion. During the design of the extrusion, the optimized design can reduce the cost of the mold and improve the production efficiency of the extrusion.

Extruded aluminum profile mold

2.1 What is an extrusion die?

Extrusion dies are basically thick circular steel disks containing one or more openings to form the desired profile. They are usually made of H-13 die steel and are heat treated to withstand the pressure and heat of hot aluminum passing through the die.


Aluminum profile

Although aluminum appears to be a very soft metal,it takes a lot of pressure to push a solid aluminum ingot (billet) through a thin,porous aluminum extrusion die to form the desired shape.

2.2 The difference between solid mold, hollow mold and semi-hollow mold

Molds for solid aluminum profiles
It can be extruded by an extruder just by processing a forming hole on the mold. Such as, for example, solid bars, angle aluminum and channel aluminum.

hollow mold
Hollow molds produce shapes with one or more voids, for example, simple round tubes, rectangular tubes, or complex multi-void t-slots.

To extrude hollow shapes, a split die is usually used. It is made of two interlocking pieces – the mandrel and the cap. The mandrel forms the internal feature of the profile and has a number of apertures separated by webs or legs for support. The cap forms the exterior feature of the profile and is assembled with the mandrel. During the extrusion process, the hot billet of aluminum will enter through the mandrel and exit through the cap.

3. Semi-hollow mold
Like hollow shapes, semi-hollow shapes have one or more voids. The difference, though, is that the voids are not completely closed, there are gaps or openings between them.

It’s a bit of a mix between the previous two types. As it turns out, there is often only a small difference between a solid shape and a semi-hollow shape.

For example, a wide aluminum trough with a partially closed void is considered solid. On the other hand, very narrow aluminum slots may be considered semi-hollow.

2.3 Life of extrusion die

Heat buildup and uneven pressure caused by the design of aluminum extrusions (such as thin walls, uneven wall thickness, and protruding features) are the biggest killers of extrusion die life.

An experienced extrusion die engineer can design the die to control heat and uneven pressure, and reduce the extrusion speed to prolong the life of the die, but eventually the die must be replaced.

Before designing aluminum extrusions, product structural design engineers should understand which design features will most significantly affect tooling costs. Where possible, changing the design of the aluminum extrusion section, setting appropriate tolerances, and selecting the appropriate aluminum alloy material can save the processing cost of the aluminum extrusion die.

2.4. The mold processing cycle is short and the cost is low

The aluminum extrusion mold is simple, the processing cycle is short, and the cost is low. This is AEC’s comparison of aluminum extrusion and other processes, for reference only.

Detailed process of extruded aluminum profiles

Extruded aluminum profile is a common processing method, and its process is mainly divided into raw material preparation, aluminum profile extrusion, aluminum profile cooling and processing. The following is the detailed process of aluminum profile extrusion:

1. Raw material preparation

Aluminum alloy materials are usually used in the production of aluminum profiles. It is necessary to heat the aluminum alloy billet to a certain temperature to reach a softened state. Generally, the extrusion temperature of aluminum alloy is between 320 and 520 °C. At this time, the aluminum alloy billet can be processed through an extrusion die.


2. Aluminum profile extrusion

During the extrusion process, the aluminum alloy billet is placed in a special heating furnace for the extrusion machine, thereby heating and softening the aluminum alloy billet. When the proper temperature is reached, the aluminum alloy billet is pressed into the extrusion die by the rotating cylinder. In the mold, the aluminum alloy material is extruded under high pressure to form an aluminum profile.

3. Aluminum profile cooling

The extruded aluminum profile needs to be cooled in order to allow the aluminum profile to return to its normal solid state. During this process, the aluminum profile is continuously sprayed with water to prevent secondary deformation.


4. Processing

Aluminum profiles need to be processed after cooling in order to meet different industrial needs. Common processing methods include cutting, welding, drilling, etc.


Factors to be considered in the design of extruded aluminum profiles

It is the primary consideration in designing aluminum profiles. The size needs to be determined according to your application needs, including length, thickness, width, etc. When determining the size of the aluminum profile, it is necessary to fully consider the load-bearing capacity and stress tolerance of the material to ensure that the profile can meet the required application requirements.

It is also an important factor to consider when designing aluminum profiles. The shape of extruded aluminum profile includes cross-sectional shape and overall shape, which is the basis for realizing product structure and function. When designing aluminum profiles, the balance between product appearance requirements and performance requirements will be fully considered.

Aluminum Alloy Selection
It is also one of the factors that need to be fully considered when designing aluminum profiles. Aluminum profiles are usually made of some special aluminum alloy materials, which have excellent performance and special uses. Therefore, when choosing an aluminum alloy, it is necessary to fully understand its performance characteristics and make a reasonable choice according to actual needs.

It is one of the factors that will inevitably appear in the production process of extruded aluminum profiles. Reasonably setting the tolerance can reduce the difficulty of the production process, ensure the accuracy and stability of the product size, and improve the overall quality of the product.

Extrusion Ratio, Tongue Ratio and Surface Finish
It is also a factor that needs to be considered when designing aluminum profiles. These factors have a great influence on the physical properties and surface quality of aluminum profiles. When formulating a design plan, these factors need to be fully considered to ensure the overall performance and quality of the product.

Finally, assembly issues also need to be considered. Aluminum profiles are often assembled with other parts in practical applications, so it is necessary to consider the degree of fit and connection with other parts to ensure the smoothness and correctness of the product assembly process.

In general, the design of extruded aluminum profiles requires comprehensive, systematic and scientific consideration of various factors to ensure that the quality and performance of the product meet the application requirements. Only in this way can we create better aluminum profile products and bring more convenience and benefits to people’s life and work.

The wall thickness of aluminum profiles that Xingda can provide

In extruded aluminum profiles, wall thickness is an important factor in determining its strength and durability.

In extruded aluminum profiles, the wall thickness that Xingda can provide is divided into three categories, which are light, medium and heavy. These different wall thicknesses are selected based on your specific application needs.

The wall thickness of light extruded aluminum profiles is generally between 1.0mm and 2.0mm. This type of aluminum profile is very suitable for the fields of architectural doors and windows, furniture, aircraft models and electronic products.

The wall thickness of medium-sized extruded aluminum profiles is generally between 2.0mm and 3.0mm. This type of aluminum profile is widely used in larger building structures and mechanical equipment.

The wall thickness of heavy-duty extruded aluminum profiles is generally above 3.0 mm. This type of aluminum profile is commonly used in the manufacture of industrial and architectural structures for support or load bearing.

In short, extruded aluminum profiles have a variety of wall thicknesses for you to choose from. Selecting the appropriate wall thickness according to your specific application requirements can ensure that your products have better performance, strength and durability, and make them more durable Play a more important role in a wide range of application fields.

Alloy State Differences – Aging

Alloys are materials made by mixing two or more metal or nonmetal elements. It is precisely because alloys have more excellent physical and chemical properties than single-element materials, making them widely used in industrial production, construction, energy, aerospace, automobile manufacturing and other fields.

However, in the use of alloys, one needs to be aware of a state difference called aging. Aging refers to the phenomenon that the properties of an alloy will gradually change over time after receiving a specific heat treatment.

The strength and hardness of the alloy after aging heat treatment will gradually increase due to the continuous increase of precipitated phases. At the same time, aging will also have a certain impact on the ductility and toughness of the alloy. Since the crystallization state of the alloy and the number and size of precipitated phases change over time, when using the alloy, the aging state needs to be considered according to the specific application scenario and requirements.

However, the aging state is not a defect of the alloy. On the contrary, for different application environments and uses, the aging state can provide more excellent performance and more adequate utilization. For example, the axles of air vehicles and the blades of aircraft engines need to have characteristics such as high strength, high hardness and high temperature stability. These properties happen to be achieved through aging states.

In short, the aging state is one of the unique state characteristics of alloy materials. In a specific application environment, by choosing an appropriate aging state, alloy materials can produce excellent performance with better performance, so as to better serve our production and life. .

Performance-enhancing surface treatments for aluminum extrusions

In order to improve the performance of aluminum extrusion products, surface treatment is a very important step. Several surface treatment methods to optimize the surface of aluminum extrusion are introduced below.

1. Oxidation treatment

Oxidation treatment is a common surface treatment method, which can improve the corrosion resistance, wear resistance and decoration of aluminum by forming an oxide layer on the surface of aluminum extrusion. Oxidation treatment methods include sulfuric acid oxidation, sulfuric acid chromic acid oxidation and nitric acid oxidation.

Advantages of oxidation treatment:
Improve the corrosion resistance of aluminum products
Greatly improve the hardness and wear resistance of aluminum products
Good appearance texture, increase color and luster
Avoids the problem of unstable chemical reactions
High-efficiency, low-cost, and environmentally friendly surface treatment methods

2. Electroless chrome plating

Electroless chrome plating is performed using a chemical reaction instead of electroplating. It is a method of forming a thin, dense layer of chromium on the surface of aluminum, which improves the corrosion resistance and decorative properties of aluminum.

Advantages of Electroless Chrome Plating
A uniform coating is formed on the surface, no dead angle, and high aesthetics.
A layer of higher hardness coating is formed on the surface, making it more wear-resistant
It is a chromium-free or low-chromium plating solution that will not pollute the environment
Low temperature treatment is not required, the process is simple, and the cost is relatively low.

3. Anodizing

Anodizing is an electrochemical surface treatment method that can improve the corrosion resistance, wear resistance and electrical properties of aluminum by forming a dense and uniform oxide layer on the surface of aluminum. In addition, anodizing can also be used for dyeing and decoration.

The hardness of the surface oxide film is greatly improved.
The hardness is generally 200~500HV
The film layer will be thickened to resist the corrosion of acid and alkali substances
Shows the metallic texture of the entire aluminum alloy workpiece
Excellent decorative effect

4. Powder Coating

It is a coating technology that sprays and heats the powder on the surface of aluminum products to adhere and form a coating, thereby providing a layer of protection and enhancing the aesthetics and durability of the material. Compared with sandblasting, powder spraying is more uniform and stable

Therefore, when selecting raw materials, they must be screened in strict accordance with the standards, and high-quality, high-purity aluminum materials must be selected to ensure that the physical and mechanical properties of the extruded products meet the standard requirements.

Quality of machinery and equipment
The requirements of precision, stability and design rationality of extrusion equipment will affect the precision and quality of extrusion products. Therefore, when purchasing machinery and equipment, you should choose a manufacturer with reliable quality, exquisite workmanship, and certain production experience to ensure the stability and production efficiency of the equipment.

Standardization of process flow
Extrusion is a very complicated process, and the processing requirements of each process are different. If there is any link omission or improper operation, it will lead to defects in the extruded product and an increase in the failure rate. Therefore, when extruding, it is necessary to check at every level according to the process standards, and comprehensively standardize the extrusion process. Once a quality problem is found, it needs to be dealt with and traced in time.

Personnel quality and quality awareness
First-class technology and equipment are important, but if there is no professionalism and good quality awareness, it will also affect the quality of the product. Therefore, provide practical operation training and quality education for workers, encourage them to continuously improve their quality awareness in their work, and take each operation link seriously and be meticulous and responsible.

Packaging method of aluminum profile

一.Non-woven fabric + kraft paper packaging
