Different brands have different proportions of different metal components. In addition to the commonly used aluminum doors and windows, such as 60 series, 70 series, 80 series, 90 series, curtain wall series and other building aluminium, industrial aluminium profiles have different grades. There is no clear model distinction, most factories are based on actual customer processing drawings. Extruding aluminium profiles is very common nowadays.
Third, it can be classified according to surface treatment requirements. It includes anodic alumina, aluminium electrophoretic coating, powder coated aluminium, wood grain transfer aluminium, planed aluminium, etc.

The heat dissipation problem of LED is the most headache problem for LED manufacturers, but aluminum substrates can be used, because aluminium has high thermal conductivity and good heat dissipation, which can effectively export the internal heat. Aluminum substrate is a unique metal-based copper clad laminate, which has good thermal conductivity, electrical insulation and mechanical processing properties. PCB should also be designed as close as possible to the aluminium base so as to reduce the thermal resistance produced by the filling glue. aluminum framing system. We are also an aluminium extrusion suppliers.

Aluminum tubes are mainly divided into the following

According to the shape: square tube, round tube, pattern tube, shaped tube according to extrusion method: seamless aluminum tube and ordinary extruded tube

According to the accuracy: ordinary aluminum tube and precision aluminum tube, the precision aluminum tube - generally need to be re-processed after extrusion, such as cold drawing, rolling, according to thickness: ordinary aluminum tube and thin-wall aluminum tube performance: resistant Corrosive and light weight. characteristic:

It is a kind of high-strength hard aluminum, which can be heat-treated and strengthened. It has medium plasticity in annealing, quenching and hot state. It has good spot weldability. The aluminum tube has the tendency to form intergranular cracks when using gas welding and argon arc welding. After quenching and cold work hardening, the machinability is good and it is not good in the annealed state. The corrosion resistance is not high, and the anodizing treatment and painting method or the surface is coated with an aluminum layer to improve the corrosion resistance. It can also be used as a mold material.

Advantages of aluminum tube: It is the advantage of welding technology: The thin-wall copper-aluminum tube welding technology suitable for industrial production is called the world-class problem, and it is the key technology of the aluminum-based copper of the air-conditioner connecting tube. ,

Second, the service life advantage: from the inner wall of the aluminum tube, since the refrigerant does not contain moisture, the inner wall of the copper-aluminum connecting tube does not corrode.

The third is the energy-saving advantage: the connecting line between the indoor unit and the outdoor unit of the air conditioner, the lower the heat transfer efficiency, the more energy-saving, or the better the heat insulation effect, the more power-saving. Fourth, excellent bending performance, easy to install, transfer machine

Aluminum tubes are widely used in various industries, such as: automobiles, ships, aerospace, aviation, electrical appliances, agriculture, electromechanical, home, etc. Aluminum tubes are everywhere in our lives.

The production process of industrial aluminum profile is that the aluminum ingots pass through the hot-melt cast rods, and the prizes are 6061, 6063, 6005, and 6082. By opening the extrusion die, heating the aluminum rods, the mold, and hot extrusion, different cross-sectional shapes are obtained. Aluminum material, then aging heat treatment. The production process of industrial industrial aluminum profile mainly includes four processes of casting, extrusion, machining and surface treatment.

Q: What are the characteristics of aluminum substrate?
A: 1. Surface mounting technology (SMT) was adopted.
2. Efficient treatment of thermal diffusion in circuit design.
3. Reduce the working temperature of the product, improve the power density and reliability of the product, and prolong the life of the product.
4. Reduce product size, reduce hardware and assembly costs.
5. Replacement of fragile ceramic substrates for better mechanical durability.

Q: What is the structure of the aluminum substrate?
A: Aluminum - based copper clad plate is a kind of metal circuit board material, composed of copper foil, thermal insulation layer and metal substrate, its structure is divided into three layers:
1. Cireuitl.Layer: equivalent to common PCB copper clad plate, thickness of copper foil loz to 10oz.
2. DiELcctricLayer insulation layer: insulation layer is - layer low thermal resistance thermal insulation material.
3. BaseLayer base: it is a metal substrate, usually aluminum or optionally copper. Aluminum - based copper clad plate and traditional epoxy glass cloth laminate, etc.

The circuit layer (i.e., copper foil) is usually etched to form a printed circuit, so that the components are connected to each other. In general, the circuit layer is required to have a large current carrying capacity, so thicker copper foil should be used, the thickness of which is generally 35ms ~ 280ms. aluminum framing system. Thermal insulation layer is the core technology of aluminum substrate, which is generally composed of special polymers filled with special ceramics, with small thermal resistance, good viscoelasticity, heat aging resistance, and can withstand mechanical and thermal stress. We are also an aluminium extrusion suppliers.

It is precisely by using this technology that the thermal insulation layer of high performance aluminum substrate has extremely excellent thermal conductivity and high strength electrical insulation performance. The metal base is the support member of aluminum substrate, which requires high thermal conductivity. Generally, it is aluminum plate, but copper plate can also be used (copper plate can provide better thermal conductivity), which is suitable for drilling, punching, cutting and other conventional mechanical processing. PCB material has incomparable advantages compared with other materials. Suitable for SMT surface mount of power element. Without radiator, the volume is greatly reduced, heat dissipation effect is excellent, good insulation and mechanical performance.

Q: What are the uses of aluminum substrates?
A: 1. Audio equipment: input and output amplifier, balance amplifier, audio amplifier, preamplifier, power amplifier, etc.
2. Power supply equipment: switching regulator DC/AC converter SW regulator, etc.
3. Communication electronic equipment: high frequency amplifier filter device, report circuit.
4. Office automation equipment: motor drive, etc.
5. Automobile: Electronic regulator, igniter, power controller, etc.
6. Computer: CPU floppy disk driver power supply unit, etc.
7. Power module: Inverter solid-state relay, rectifier bridge, etc.
Q: What are the advantages of LED industrial aluminum profile?
A: 1, led lamps need to heat good materials, and aluminum has much higher thermal conductivity than steel;
2, industrial aluminum profile are well processed, many shops can get it, and the materials are convenient;
3. The surface of the aluminum has a layer of dense alumina, which has good anti-oxidation and corrosion effects;
4. Finally, aluminum is cheaper than stainless steel and the price is right.

Q What are the cooling methods for LED lights?
A: LED heat dissipation methods include radiation and conduction and convection.
    Radiation means that the body emits infrared light to dissipate heat. When the skin temperature is higher than the ambient temperature, the body's heat is lost by radiation. Radiation heat dissipation is related to skin temperature, ambient temperature and effective radiation area of the body. In general, the radiated heat dissipation accounts for 40% of the total heat dissipation. Of course, if the ambient temperature is higher than the skin temperature, the body will absorb the radiant heat. Steel workers work in front of the furnace, and this is also the case when farmers work in the field under the heat of the summer in the hot summer.
    Conduction is the body's ability to dissipate heat by transmitting molecular kinetic energy. When the human body is in direct contact with objects that are cooler than the skin (such as clothes, beds, chairs, etc.), the heat itself is transmitted to these objects. Clinically, using ice caps, ice packs, etc. to cool patients with high fever is to use this principle.
    Convection is the flow of air, which uses air as a medium to dissipate heat.
    Aluminum radiators are the most common radiators in the early days. The manufacturing process is simple and the cost is low. So far, aluminum radiators still occupy a considerable part of the market.

Q: What details should be paid attention to during the spraying process of LED lamp industrial aluminum profile?
A: 1. The selection of the fixture and the feeding method: the fixtures at both ends should ensure that they can withstand the pressure of considerable weight; the fixtures used in the middle part should minimize the contact points between the fixture and the profile during the production and use. The size of the hanging rods placed vertically in the middle should be replenished in time, and the hanging position in the hangers of the profiles should also follow the corresponding principles.
2, the problem should be paid attention to in the spray booth: before the official dusting, you can test the spray several times. At this time, you can observe the amount of powder and the uniformity of powder distribution at both ends of the spray booth. At this time, the powder runs in a straight line within 10 cm from the end of the claw, and the other part is in the form of atomized powder. The powder adsorbed on the surface of the profile is actually the powder of the atomization effect, and whether such atomization exists. The effect of the powder is used as a standard for controlling the distance between the jaws and the profile.
3. The pre-treatment process is simpler than the pre-oxidation pre-treatment process, mainly degreasing and chromizing, and the raw material consumption is low. In order to improve production efficiency and reduce energy consumption during the pre-treatment process, a larger rack is used, and as many profiles as possible are to be processed. For some softer profiles, place the crossbar in the middle of the profile and place the groove as far as possible to help evaporate the water.
4. When the drying process is completed, when there is still water residue, in order to avoid breaking the surface of the aluminum lamp on the surface of the LED lamp and the temperature is too high, the profile is easily deformed and should not be baked in the furnace. Dry or dry. At the same time, the aluminum profile of the LED lamp enters and exits the groove and must maintain a proper inclination angle during the dripping process, but it is easy to cause some of the profile to slip. We are also an aluminium extrusion suppliers. A stainless-steel wire mesh should be bundled at a certain end of the material frame as a precautionary measure.

The picture above shows the LED material aluminum profile for the LED lamp shell.

LED lamp shell is made of plastic-absorbing acrylic board, which absorbs light evenly, so the light emitted through acrylic board is very soft and pure. We are also an aluminium extrusion suppliers. The function of the LED lamp shell is that it not only covers the lamp to make the light gather together, but also can prevent static electricity and protect the eyes, so each lamp has a lamp shell.

LED lamps need materials with good heat dissipation, and aluminium has a much higher thermal conductivity than steel; aluminium profiles are processed well, and many stores can handle them easily; aluminium surface has a dense layer of alumina, which has a good anti-corrosion effect; finally, aluminium is cheaper than stainless steel, and the cost is similar to that of die castings. aluminum framing system. As for benefits, that's what many factories can produce.

LED lamps and lanterns, can choose different light colors of the LED combination into a variety of modules with soft illumination, arbitrarily be installed in the living room, the light source of the lighting lamps in the living room may come from the ground, wall, window sill, furniture, ornaments, etc. Therefore, in the future, the room lighting will no longer be limited to a single lamp, but will be transformed from a single lamp lighting into a shadow less lamp without the overall lighting effect of the sense of lighting appliances. Different light colors and brightness have different effects on people's physiology and psychology. In many cases, people do not need very bright white light. It is possible that yellow light or other color light is more suitable for physiological and psychological needs. Tri-primary color LED can realize continuous transformation and selection of brightness, gray level and color, which makes illumination expand from white light in general sense to multi-color light. LED lamps made of aluminium alloy are welcomed by the market because of the particularity of materials and the strong heat dissipation of aluminium alloy itself.

With its light weight, good thermal conductivity, good mechanical properties at high and low temperatures, excellent processing performance and high cost performance, aluminium is unique in the field of LED lighting heat dissipation materials. Aluminum alloys play an important role in heat dissipation of LED lighting fixtures: they play a very important role in the market of main materials for LED lighting because of their diverse application forms. Aluminum alloy materials are widely used in LED lamps. From the application form, there are mainly die-cast aluminum, industrial aluminum profile, forged aluminum, aluminum plate, etc. aluminum framing system. From the parts applied to LED lamps, the main components are the shell, driver, aluminum substrate and fixed support of LED lamps.
