How To Produce 4×8 Aluminum Sheet

The production process of 4×8 aluminum sheet plate is basically the same as that of regular size aluminum plate. The following is the detailed production process of aluminum plate:


(1) Ingredients: Calculate the addition amount of various alloy components according to the specific alloy grades to be produced, and reasonably match various raw materials.

(2) Smelting: Add the prepared raw materials into the smelting furnace according to the process requirements and heat them to 950°C-1200°C for melting, and effectively remove the impurities and gas in the melt by means of degassing and slag removal refining.

Melting And Casting

Melting And Casting

The melting point of aluminum is around 660°C

(3) Casting: The smelted aluminum liquid is in a certain casting process, including casting, extrusion and fish on-line, including: oxidation, electrophoretic coating, fluorocarbon spraying, powder coating, grain wood transfer, etc.) three processes.

The cast aluminum plate also needs to be processed to obtain better material properties. This process is rolling, also called calendering.

Rolling can be considered as the following two types:

Cold Rolling

Cold rolling refers to the process of compressing and deforming metal billets by rolling force at room temperature to improve their strength, hardness and dimensional accuracy, and to achieve thinning, homogenization and smoothing of metal materials.

Cold rolling can not only realize the thinning of metal materials, but also improve the precision, strength, hardness and surface finish of materials, which is a very important method in metal processing.

Rolling Machine

Rolling Machine

Cold rolling is processed at room temperature and will not cause thermal effects on metal materials, so precise control of materials can be achieved.

Hot Rolling

Hot rolling is the process of compressing, bending and forming metal sheets or strips at high temperatures to finally obtain metal products with the desired shape and properties.

In the hot rolling process, metal sheet heated to certain temperature, usually above the recrystallization temperature. Then fed into rolling mill where they are rolled several times at high temperatures, gradually forming them into the desired shape and thickness.

During the rolling process, the temperature of the metal sheet or strip is usually kept above 800°C.

The hot rolling process has many advantages, such as high production efficiency, low cost, and high material utilization rate. Therefore, it is widely used in the field of metal processing.

Rolled aluminum and aluminum alloy materials are available in coil form.

Stretching And Straightening

After the 4×8 aluminum sheet is rolled, it still needs further processing to improve its strength and plasticity. Stretching is required here, and the rolled aluminum sheet is put into a stretching machine for processing.

Stretching And Straightening

Stretching And Straightening

During the stretching process, attention should be paid to key points such as stretching speed, temperature, and stretching degree to ensure that the mechanical properties of the 4×8 aluminum sheet plate meet the requirements.

Cutting And Surface Treatment

After finishing the anodizing and coating treatment, the aluminum plate needs to be cut and surface treated. Cutting can adopt methods such as laser cutting, water jet cutting or mechanical cutting according to needs.

The cut aluminum plate needs surface treatment to eliminate the burrs and sharp angles left by cutting, and improve the safety and aesthetics of the aluminum plate.

Cutting And Surface Treatment

Cutting And Surface Treatment

Surface Treatment Process


Polishing treatment refers to polishing the surface of the aluminum plate to a mirror state by mechanical means, which can enhance the decorative effect and reflective performance of the aluminum plate.


Anodizing is the most commonly used method in surface treatment of aluminum sheets. In this method, an aluminum plate is used as an anode, and an oxide film is formed on the surface of the aluminum plate by electrolysis, and the film has high hardness and good corrosion resistance.

Coating Treatment

Powder coating

Powder coating is an advanced and efficient coating process. Its basic principle is to spray plastic powder on the surface of the workpiece and heat it to melt to form a uniform coating.

Coating Treatment Of 4x8 Aluminum Sheet

Coating Treatment Of 4×8 Aluminum Sheet

Powder coating has the following advantages: dense coating, corrosion resistance, wear resistance, rich color and long-lasting color, suitable for coating various metals, plastics, wood and other materials.

Roller Coating

Roller coating is a more traditional method of coating application. It uses a roller to spread the paint evenly on the surface of the workpiece.

The advantage of roller coating is that the construction is simple, fast, and the cost is low, and it is suitable for the coating of large area walls. However, compared with powder spraying, the coating quality of roller coating may not be as good as the former, and the color is not rich enough.

When choosing powder spraying and roller coating, it is necessary to make a trade-off according to specific application scenarios and requirements.

Inspect The Package

After cutting and surface treatment, the final quality inspection of the aluminum sheet is required. Quality inspection includes checking the size, thickness, surface quality and other aspects of the aluminum plate.

Packaging And Shipping

Packaging And Shipping

The formula for calculating the weight of the aluminum sheet is:

weight = volume x density


The density of the aluminum sheet is 2.7g/cm³

Foot (ft) 1 foot = 12 inches = 30.48cm = 304.8mm.

Inch (in) 1 inch=2.54cm==25.4mm.

4×8 Aluminum Sheet Of 1/8 Inch Volume

volume = length x width x thickness

4 feet = 1219 mm ≈ 122cm

8 feet = 2438 mm ≈ 244cm

1/8 Inch = 3.175 mm = 0.3175cm

Inserting the formula yields:

Volume = 122cm x 244cm x 0.3175cm ≈ 9451cm³


4×8 aluminum sheet of 1/8 inch weight is

Weight = 9451cm³ x 2.7g/cm³ = 25517.7g ≈ 2.55kg

Casting production process and its introduction

The purpose of melting and casting is to produce alloys with satisfactory composition and high purity of melt, so as to create favorable conditions for casting alloys of various shapes.

Melting and casting process steps: batching --- feeding --- melting --- stirring after melting, slag removal --- pre-analysis sampling --- adding alloy to adjust the composition, stirring --- refining --- static Setting——Guide furnace casting.

Hot rolling production process and its introduction

  • 1. Hot rolling generally refers to rolling above the metal recrystallization temperature;
  • 2. During the hot rolling process, the metal has both hardening and softening processes. Due to the influence of deformation speed, as long as the recovery and recrystallization process is too late, there will be a certain work hardening;
  • 3. The recrystallization of the metal after hot rolling is incomplete, that is, the coexistence of recrystallized structure and deformed structure;
  • 4. Hot rolling can improve the processing performance of metals and alloys, reduce or eliminate casting defects.
    • Hot rolling equipment

      Casting and rolling process

      Casting and rolling process: liquid metal, front box (liquid level control), casting and rolling machine (lubrication system, cooling water), shearing machine, coiling machine.

      • 1. The casting and rolling temperature is generally between 680°C and 700°C. The lower the better, the stable casting and rolling line usually stops once a month or more to re-stand. During the production process, it is necessary to strictly control the liquid level of the front tank to prevent low liquid level;
      • 2. Lubrication uses C powder with incomplete combustion of gas for lubrication, which is also one of the reasons for the dirty surface of casting and rolling materials;
      • 3. The production speed is generally between 1.5m/min-2.5m/min;
      • 4. The surface quality of products produced by casting and rolling is generally relatively low, and generally cannot meet products with special physical and chemical performance requirements.
        • Cold rolling production process

          • 1. Cold rolling refers to the rolling production method below the recrystallization temperature;
          • 2. There will be no dynamic recrystallization during the rolling process, and the temperature will rise to the recovery temperature at most, and the cold rolling will appear in a work hardening state, and the work hardening rate will be large;
          • 3. The cold-rolled sheet and strip have high dimensional accuracy, good surface quality, uniform structure and performance, and products in various states can be obtained with heat treatment;
          • 4. Cold rolling can roll out thin strips, but at the same time, it has the disadvantages of high energy consumption for deformation and many processing passes.
            • Casting rolling

              Introduction to finishing production process

              • 1. Finishing is a processing method to make the cold-rolled sheet meet the customer's requirements, or to facilitate the subsequent processing of the product;
              • 2. The finishing equipment can correct the defects produced in the hot rolling and cold rolling production process, such as cracked edge, oily, poor plate shape, residual stress, etc. It needs to ensure that no other defects are brought into the production process;
              • 3. There are various finishing equipments, mainly including cross-cutting, slitting, stretching and straightening, annealing furnace, slitter, etc.
