Anodising is a treatment process in which an oxide film is formed on the surface of the metal by an electrolytic oxidation reaction. In this process, the metal or alloy part is used as an anode to form an oxide film with protective, decorative and other functional properties on its surface by the action of an applied electric current under specific electrolyte and process conditions.

Black anodising is the electrochemical process of darkening aluminium parts by first performing standard anodising to form a semi-porous aluminium oxide layer. The oxide layer is then dyed black using one of the three dyeing techniques: organic dyes, inorganic dyes or electrolytic dyeing of metal salts.

Metals that can be black anodised are aluminium, magnesium and titanium, of which aluminium is the most commonly used for black anodising, but not all grades of aluminium can be black anodised, only the alloy 5000 series, alloy 6000 series and alloy 7000 series of aluminium can.

Black anodising works by first anodising the part using the standard anodising process and the Type II or Type III anodising process. For optimum colour fastness, a minimum thickness of 25 microns or more is recommended for the anodised coating. After anodising, the part will have a semi-porous surface structure and these pores are used to accommodate the black dye. There are three dyeing techniques:

Organic dyes are dissolved in warm water and placed in a dye bath, followed by the part, and the dye will fill the semi-porous surface of the anodic layer. Typically, black dyeing requires additional dyeing time compared to lighter colours. Organic dyed parts are not recommended for outdoor use.

These pigments are insoluble in water and the coatings they produce have excellent lightfastness. For black anodising, parts can be produced using cobalt sulphide inorganic salts.

After standard anodising, the part is placed in another electrolytic tank containing a solution of heavy metal salts. The anode layer acts as the cathode and the stainless steel electrodes are placed in an acidic electrolyte bath where the metal salts will then be deposited to the bottom of the holes. Nickel, cobalt and tin salts are used to produce different colours, a proprietary process that produces parts with superior colour fastness.

• Home appliance field: commonly used in home appliance shells, handles and other parts, to improve the texture and grade of the product.
• Automotive field: widely used in automotive parts, such as wheels, body trim, etc., to increase the sense of fashion and luxury car appearance.
• Electronic field: commonly used in mobile phones, tablet PCs and other electronic products on the shell and keys, to improve the texture and durability of the product.
• Architectural field: it can be used on building curtain walls, doors, windows, ceilings and other components to increase the modern and artistic sense of the building.

In addition, black anodized aluminium has a wide range of applications in other industrial fields such as the aviation manufacturing industry and the automotive industry, such as improving the hardness and wear-resistant properties of aircraft parts, as well as improving the surface hardness and anti-corrosion properties of automotive parts.

The benefits of black anodizing include improved wear and corrosion resistance, and this finish ensures that anodized aluminum components are less prone to rust. Rust is often used to describe the formation of a destructive flaking oxide layer on ferrous metals, and when an oxide layer forms on aluminium, it adheres to the surface of the metal and prevents further oxidation of the substrate.

In addition, black anodising has some additional specific benefits:

• Thermal Emissivity: Aluminium components are often dyed black to increase their emissivity and applications can include heat sinks as well as satellite components.
• No outgassing: Black anodised parts, if properly sealed after dyeing, will not outgas when exposed to a vacuum, and the lack of outgassing helps to protect sensitive equipment.
• Colour fastness: Black anodised parts, especially when dyed with inorganic or metallic salts, have excellent colour fastness, meaning they will generally retain their colour when exposed to UV (ultraviolet) light.

While black anodising is a robust finishing process with significant advantages, it also has limitations:

• Surface cracks: When exposed to thermal cycling, black anodised parts can form cracks in the anodic coating, which are mainly due to the difference in thermal expansion rates between the substrate and the coating.
• Limited Materials: Not all aluminium series can be black anodised. In general, the most common anodised aluminium series are 5000, 6000 and 7000, with 6000 being the most common anodised series.
• Fading: If organic dyes are used, black anodised parts will tend to fade as they are not suitable for UV exposure.

Although black anodising has a wide range of applications and many advantages, it is necessary to pay attention to its possible shortcomings in the process of application in order to take appropriate measures for prevention and treatment.

Aluminum is a widely used material in the construction industry due to its excellent properties such as light weight, high strength, and corrosion resistance. However, to further enhance its durability and aesthetic appeal, surface treatment is required. One of the most popular surface treatments for aluminum is fluorocarbon coating.

Fluorocarbon coating is a type of coating that has become increasingly popular in recent years due to its many beneficial properties. This coating is often applied to aluminum surfaces, especially in the construction industry where it is commonly used on the exterior walls of high-grade buildings. Fluorocarbon coating, also known as PVDF coating, is a type of coating made from polyvinylidene fluoride (PVDF) resin. This type of coating is highly resistant to weathering, corrosion, and UV radiation. In addition, it has a high level of hardness, good abrasion resistance, and is highly durable. Its exceptional properties make it highly desirable for use in a variety of applications, including the construction industry.

The application of fluorocarbon coating on aluminum plates in the construction industry is highly popular due to its aesthetic appeal, high durability, and resistance to weathering. The coating enhances the appearance of buildings and protects against harsh environmental conditions that can cause damage to the building’s exterior. The use of fluorocarbon-coated aluminum plates has become increasingly popular in the construction of high-grade buildings due to its exceptional properties.

The production process of fluorocarbon coating involves several steps, including surface treatment, coating, drying, and curing. The surface treatment process involves cleaning, degreasing, and chemical conversion of the aluminum plate to improve adhesion. The coating process involves spraying the PVDF resin onto the surface of the aluminum plate and then drying and curing it at high temperatures.

The standard for inspection of fluorocarbon coating in the construction industry is highly important to ensure the quality and safety of the building. The inspection standards require that the coating meets specific criteria, including adhesion, thickness, and appearance.

Powder coating is another type of coating that is often used in the construction industry. While both fluorocarbon coating and powder coating have their strengths and weaknesses, the choice between the two largely depends on the specific application. Fluorocarbon coating is highly durable, has a high level of hardness, and is resistant to weathering and UV radiation. In contrast, powder coating is highly resistant to impact and abrasion, making it suitable for applications that require a high level of durability.

For more information about Powder Coating and PVDF, please visit our previous Blog: Powder Coating Vs PVDF Coating On Aluminium Surface

In conclusion, the use of fluorocarbon coating in the construction industry is highly beneficial due to its exceptional properties. The coating enhances the appearance of buildings and provides protection against harsh environmental conditions. While there are other types of coatings available, fluorocarbon coating is highly desirable due to its durability, resistance to weathering and UV radiation, and overall strength.

Many people are concerned about whether die-casting aluminum alloy can be done with anodizing treatment. It is actually very difficult to anodize the die-casting aluminum parts. Anodic oxidation is the process of oxidizing the anode in a suitable electrolyte using electrochemical methods under certain voltage and current conditions, in which the alloy part is used as the anode and stainless steel, chromium, or the conductive electrolyte itself is used as the cathode, thus obtaining an anodic oxide film on the surface of the workpiece, anodic oxidation, and coloring process requires sulfuric acid anodic oxidation.

The limitations of sulfuric acid anodizing for aluminum alloy materials are as follows:

1. The presence of alloying elements reduces the quality of the oxide film. Under the same conditions, the thickest oxide film, the highest hardness, the best corrosion resistance and the best homogeneity is obtained on pure aluminum. For aluminum alloy materials, it is necessary to ensure the aluminum content, usually not less than 95 %, in order to obtain good oxidation results.

2. In alloys, copper reddens the oxide film, destroys the quality of the electrolyte and increases oxidation defects. Silicon can turn the oxide film gray, especially when the content exceeds 4.5%. Due to its own characteristics, iron will exist as black spots after anodizing.

3. Die-cast aluminum alloys: Cast and die-cast aluminum alloys usually contain high silicon content, and the anodic oxide film is dark, so it is impossible to obtain a colorless and transparent oxide film. As the silicon content increases, the color of the anodic oxide film changes from light gray to dark gray to dark gray. Therefore, cast aluminum alloys are not suitable for anodizing.

Commonly used die-casting aluminum alloys can be divided into three main categories.
First, aluminum-silicon alloys, mainly containing YL102 (ADC1, A413.0, etc.), YL104 (ADC3, A360).
Second, aluminum-silicon copper alloys, mainly containing YL112 (A380, ADC10), YL113 (A383, ADC12), YL117 (B390, ADC14).
Third, aluminum and magnesium alloys, mainly containing 302 (5180, ADC5, ADC6).

As a result of the global epidemic, the natural environment is deteriorating. People’s awareness of protection is increasing. Face mask machine demand is also expanding. Many manufacturers have found the mask machine industry profits, and have expanded production. For the mask machine, everyone may be relatively unfamiliar. The framework of making mask machine equipment is the industrial aluminum profile. And it’s generally aluminum profile S8-4080.

— Strong Bearing Capacity. 4080 Aluminum Profiles are generally divided into light and heavy profiles. They are the only difference in wall thickness and bearing capacity. But for the general mask machine, 4080 light can meet the demand.

— 4080 Aluminum Extrusion is treated by anodizing. It has the functions of anti-corrosion, sterile clean, and easy to process and handle. The equipment assembled with 4080 profiles is stable and durable. It is also convenient to expand and upgrade the equipment in the later stage.

The whole framework adopts the assembly line aluminum 4080 and 4040 aluminum profiles, which are connected with the inner hexagon bolts. Mobile casters are installed at the bottom for flexible movement.

A part of the aluminum frame is used to hang the raw material used to make masks. The part is an aluminum shaped chassis working table, which is used for mask making equipment (welding equipment, bearing, etc.). The framework can be automated that can increase production.

First of all, whether it is a masking machine assembly line or protective clothing production equipment assembly line, are required to customize. Each type of equipment and specifications are different. Custom-made frames made of industrial aluminum profiles have more advantages than those made of materials such as stainless steel. It doesn’t have to be welded, it doesn’t have to worry about gaps and instability.

Secondly, the aluminum surface is anodized to ensure the anti-corrosion and durability of aluminum. Mask machine production works long hours. It has high requirements for equipment. Production mask environment in the dust-free workshop operation. The mechanical equipment of the mask is easy to clean.

Finally, aluminum can be processed with the size of the machine. Such as assembly line workbench, conveyor mask chain, mask machine equipment frame. Customers only need to provide design and processing drawings. HOONLY CNC machining center provides perfect after-sales service.

The outdoor application of powder coating is becoming more and more common. People pay more attention to the weather-ability and durability of powder coating products. Especially for aluminum profiles, ceilings, curtain wall panels and other outdoor supplies surface. How to improve the weather-ability of powder coatings for aluminum is particularly important.

Powder coatings are mainly composed of resins, binders, additives, and color pigments. With the time going, the properties of the coating film on the surface of aluminum profiles will decrease gradually due to the effects of natural factors such as sunlight, rain, oxidation, cold and heat changes, and microorganisms. This process is called “aging”. The ability of powder coatings to inhibit or retard natural aging is called natural aging resistance, or aging resistance. Also known as weather resistance.

There are many factors that affect the weather-ability of powder coatings. It includes the internal factors such as the performance of resins, binders, additivers and color pigments. As well as the process conditions and curing degree of powder coatings. There are also the use of film environment such as the role of sunlight (mainly ultraviolet), the composition of the atmosphere (oxygen, ozone, industrial smoke, etc.), humidity (including acid rain, salt fog, etc.), temperature changes and other external factors.

To improve the weather ability of powder coatings, the first step is to select the raw materials which can meet the requirements of aluminum profile industry. And the qualified raw materials should also meet the other properties of the coating film.

Since resin is the main film-forming material of powder coatings. And it’s the most important component that determines the properties of films. The selection of Resin is very important.

Although the Curatives of HAA system is well known. Its disadvantage is that the by-product is formed in the curing reaction. And pinholes and porcine pores are easy to be produced in thick spraying. The yellowing resistance and durability of overbaking film are not as good as those of TGIC system. At present, it is difficult for aluminum profile industry to accept these disadvantages of HAA system. Most powder manufacturers have not solved these problems. So the TGIC system is still the main powder coating for aluminum profile. The curing agent TGIC also has an effect on the weather ability of powder coatings.

The influence of pigment on the weather ability of powder coatings is the most important factor in raw materials except resin. Because pigment will fade during use. Even if one color is used, in the market, there are many kinds of pigments. And the properties of different pigments (such as hue, coloring power, covering power, weather ability and heat resistance) are very different. This gives us a great difficulty to choose.

The important function of additiver is to improve the hardness, rigidity and scratch resistance of coating film after it is added to powder coatings. At the same time, it is beneficial to improve the storage stability, looseness and electrification of powder coatings. Barium Sulfate is the most commonly used additiver for aluminum profiles. Thus, to ensure the weather ability of coatings, it is necessary to use high purity barium sulfate as additiver.

In powder coatings formulation, the amount of crosslinker is very small. But in general powder coatings formulation composition, crosslinker is an indispensable component. And it plays a decisive role on film appearance and some properties . To improve the weather ability of powder coatings, consider using anti-aging wax powder and matting agent is available.

By calculating the acid value of polyester resin in powder coatings and the hydroxyl equivalent of curing agent, the suitable amount of curing agent is designed. The optimum amount of curing agent is used to make the coatings fully solidify when curing, which is verified by accelerated aging test. To achieve the best weather resistance.

On the premise of satisfying the properties of powder coatings, reduce the kinds of raw materials, especially the materials which have negative effect on the weather ability of coatings. On the premise of not affecting the covering power, hardness and wear resistance of the coating film. The amount of pigments and additivers in the formulation (especially the pigments with large oil absorption capacity) should be reduced appropriately. So that the pigments in the formulation can be fully covered by resin in the melting and mixing process. In the course of using the coating film, reduce the color change of the pigment. To improve the weather ability of the coating film.

The manufacturing process of powder coatings mainly includes four stages: pre-mixing, melting extrusion, crushing and grading crushing. The two processes of pre-mixing and Melt extrusion have great influence on the weather ability of powder coatings.

The purpose of premixing is to make the raw materials in the powder coating formula disperse evenly. The purpose of Melt extrusion is to make the various components in the composition of the powder coating mix evenly. To improve the weather resistance, in the melting extrusion stage, under the premise of no gelling particles, the temperature of extruder should be raised properly. (especially under the condition of lower temperature), so that the resin can melt into a kind of fluid. To ensure that the pigment can have a good wetting and obtain the maximum shear force. And it is conducive to high dispersion of pigments, so that the components into a uniform system.

While ensuring the production progress, the extrusion speed can be appropriately reduced to ensure that the materials have sufficient melting and mixing time. Thus improving the mixing effect. So that the pigments and additivers in the powder coatings are fully covered by resin. And the particles of various raw materials are dispersed evenly. Especially the curing agent and resin can be mixed according to the proportion of the formulation. The film can be solidified when cured, thus increasing the surface compactness of the film. Finally, the weather ability of the powder coating is improved.

Only when the powder coating is cured, the polymer chain of the resin will be fully cross-linked with the curing agent. And the Physical Chemistry Properties will reach the best state. Weather resistance is no exception. Thus, to improve the weather ability, the powder coating must be fully cured. And well controlling the temperature and time.

In summary, to improve the weather ability of powder coatings for aluminum profiles. We can refer to the following ideas. Choose the resin with good weather ability and leveling not too bad. The formulation structure is designed to improve the weather ability of the coating film. And the production process of the powder coating was well controlled.

Aluminum profiles can be widely used in the production of advertising light boxes. The light box aluminum profile has the advantages of corrosion resistance. The service life is long and easy to install. Today we briefly introduce 4 types of light box aluminum profiles.

Aluminum profile for fabric light box has the structure of rounded, profiled and bent. The size covers from 2.5 mm to 12 mm. The wall thickness is 0.5-2.0 mm. Due to aluminum profiles have rich surface colors. the most commonly used surface colors of light boxes are Sand White, Sand Black and Sand Gold. The fabric light box can be installed indoors and outdoors. For outdoor installation, please choose 1.5 mm to 2.0 mm wall thickness of aluminum profiles. And note that built-in waterproof light strips. Application scenarios such as mobile phone store, clothing store, supermarket, etc.

Aluminum profile for Frameless Fabric LED Light Box, a structure on which the four sides of the frame can open. Mainly used in the project outdoor display advertising. The most important for Frameless Fabric Light Box is the aluminum wall thickness. It decided to install the outdoor light box can bear the wind and corrosion resistance. Thus the thickness should be 1.5 mm to 2.5 mm. Light box color can also be a variety of choices. Electrophoretic white, Anodizing in Silver, Sand black and gold.

Ultra Slim Aluminum Light Box, because of its thin wall and small, very popular to customers. There are single-sided and double-sided, both with open frames. The wall thickness is during 1 mm to 1.5 mm. A variety of surface colors are available. The ultra slim light box can use as poster for restaurant, fruit shop advertising.

The Indicated Light Box has the function of guiding and direction. Mainly used in the subway, high-speed railway, stations, parking garages, to guide people to where to go. To be customized according to site requirements.

For these outdoor exhibition equipment, advertising equipment and other companies. Hoonly can help you customize all kinds of aluminum profiles. And give you workable and reliable solutions.

The alloys used for extruding heat sinks must have good thermal conductivity. The general alloys used are 1A30,1035 and 6063. At present, 6063 alloy is widely used. Because it has good thermal conductivity and good mechanical properties.

To ensure the quality of aluminum extruded heat sink. We should start from the following four aspects:

The alloy composition of ingots should be strictly controlled. To ensure the purity of the alloy melt. The ingot should be fully homogenized so that the structure and properties are uniform. The surface of ingot must be smooth and no segregation or sand. The end of the INGOT should be flat, not cut into steps. (cut slope should be less than 3 mm)

Because the aluminum heat sink tool has a lot of verminous fins. They will be under great pressure when extruding process. Each fin has to be very strong and tough. So the quality of steel die must be reliable. We recommend H13 Tool Steel.

Tool Heat treatment is very important. To use vacuum heating quenching. And it is best to use high-pressure pure nitrogen quenching. That can ensure the uniform performance of each part of the die after quenching. After quenching, three times of tempering should be adopted. To ensure that the hardness of the tool has enough toughness under the premise of HRC48 ~ 52. This is an important condition to prevent the broken fins.

To prevent the fins broken, the extrusion pressure should reduce as far as possible. The extrusion force relates to the length of the aluminum rod, the deformation resistance of the alloy, and the degree of deformation. So, the length of the cast bar should not be too long, which is about 0.6 ~ 0.85 times of the normal length.

For the section of aluminum heat sink with complex shape. Besides shortening the length of casting bar. Considering to use pure aluminum short casting for the first extrusion test. Then use normal casting bar for extrusion production after successful extrusion test.

Homogenization annealing of ingot can not only make micro-structure and properties uniform. But also improve extrusion properties and reduce extrusion pressure. So, uniform annealing is necessary for ingot casting.

The key to the production of aluminum heat sink profile is the first trial of extrusion die. The operator should allow the main plunger to advance at a low pressure of less than 8MPa. After each fin of the die is uniformly extruded out. It can gradually pressurize to speed up the extrusion. Pay attention to the heating temperature of the tool/die when extrusion process. The die temperature should be close to the cast bar’s.

Choose the right heat sink for your needs, you can consult us freely.

The development of modern industry requires more and more high-performance motor. The thermal loss problem restricts the design and development of large capacity motor. Whether the cooling medium through the motor interior or not. We divide motor cooling into Internal Cooling and Surface Cooling. Small or medium-sized motors use surface cooling due to the limitation of volume.

According to the different cooling medium, we divide into air cooling motor and liquid/water cooling motor. The advantage of air cooling is low running cost. But there are many disadvantages: high friction loss and low heat dissipation efficiency. So air cooling motor applies to low energy density and low heating motor structures.

The disadvantage of water-cooled motor is high running cost. But there are more advantage: small friction coefficient and high heat dissipation efficiency. So water-cooled motor applies to high energy density and high heat output motor structures.

The secret is that the motor body adopts sealed water circulation. The flowing water through the motor body takes the heat away. But how to achieve water flow in the motor housing without leakage?

Aluminum alloy has good plasticity and thermal conductivity. And aluminum alloy profile has high tensile strength. These excellent properties make aluminum alloy as the best material of Motor Housing. With the continuous improvement of modern extrusion technology. The large-section motor body can be extruded as a whole. Thus replacing the traditional motor shell which relies on the welding joint.

The extruded water-cooled Motor Shell has a compact structure. It adopts inner wall spiral water distributing tank. Special argon arc welding process makes the junction of water channel more sealed. The spiral waterway in the shell divides into water inlet and water outlet. The water flow can take away the heat generated during the high-speed operation of the motor.

1. Aluminum Extrusion Die/Tooling Technology. The die/tooling determines whether the water-cooled motor body can be formed. The mold/die design and manufacture are not the focus of today’s discussion.
2. Aluminum Extrusion Process. The emphasis is on “3 Temperatures” Controls. The topic has discussed in our previous BLOG. Learn more: Analysis on Production Process of 6063 Alloy Extruded Profiles.
3. Argon Arc Welding Process. Lear more to visit Several Advanced Aluminum Alloy Welding Techniques.

The main problem of aluminum motor is the internal diameter concentrically tolerance. Large tolerance can cause friction between the rotor and the inner wall of the motor housing. So it makes a lot of noise. The new type of water-cooled motor processes two ends accurately. Controlling concentrically error ≤0.02 mm. And it extends the motor more than three times service life.

The water-cooled motor housing can apply in many fields. Especially the emerging new energy automobile industry. You can follow us for more information and feel free to contact us if you have any questions.

T-slot aluminum profiles have many benefits. The shape of T-slot profile creates modularity. It is easy to assemble and reassemble to meet evolving requirements. But careful friends will find that not all T-slot width of profiles is the same, Why?

It’s known the T-slot provides the ability to add connections and join profiles to captivated ends. And the majority of profiles can combine with each other with connectors. The T-slot width will directly determine whether most fractional fittings can be used.

In term of Design: Small Cross-Section of T-slot aluminum profiles has a small slot. It looks better from the outside. Hoonly’s 20 series profiles T-slot width is 6.2 mm, the extra 0.2 mm is for the M6 nut to pass through smoothly.

In term of Light-Heavy Loading: The light-duty frameworks use the profiles in slot width 6 mm. The heavy-duty frameworks use the profiles in slot width 8 mm.

In China, most fractional 30 series profiles’ slot width is 8 mm, but many other countries use 6 mm slot width. Both two specifications are gainable at Hoonly.

The wide variety of T-slot Aluminium profiles ensures that we offer a profile to cover virtually any application. Selecting which profiles are right for your applications? It may be a question of function, appearance, strength, or a combination of all the above.

Before choosing the appropriate aluminum profiles, you need to consider the expected load firstly. By calculating the stress caused by material strain, you can get the correct size of the profiles.

When installing accessories, you should avoid profile cracking.

If you have problems choosing a profile or accessory, please get in touch with us. We would be glad to assist you with detailed advice.
