First, the base material is pre-treated, including anodizing, chromium plating and other processes, to improve the surface finish and corrosion resistance of the base material. Then the coating material (usually polyethylene resin) is evenly coated on the surface of the substrate through coating equipment to form a uniform protective layer. The selection of coating materials and coating process have an important impact on the quality of aluminum foil paper.
  • 3. Drying: After coating is completed, the substrate needs to be dried to remove moisture from the coated material and ensure the stability and quality of the aluminum foil paper.
  • 4. Coiling: The dried aluminium foil paper is rolled into rolls. It can be rolled into different specifications according to customer needs, and is generally divided into large rolls and small rolls.
  • 5. Cutting: The rolled aluminum foil needs to be cut and customized into aluminum foil papers of different sizes according to customer needs. The cutting process usually uses cutting machinery to ensure accurate cutting dimensions.
  • 6. Packaging: The cut aluminum foil needs to be packaged. The conventional packaging method is to package it into boxes or rolls, and then mark the packaging information.

How to calculate the price of aluminum foil paper?

The calculation of the price of aluminum foil is mainly related to factors such as material cost, production cost, transportation cost, market supply and demand. Generally speaking, the price of aluminium foil will be comprehensively considered based on these factors and a reasonable price will be determined.

First of all, the price of aluminum foil is closely related to the cost of materials. Aluminum foil paper is made of aluminum material, and its price is affected by the supply and demand of raw materials and price fluctuations. Fluctuations in aluminum prices, stable supply, and material quality will directly affect the cost of aluminum foil.

Secondly, production cost is also an important factor affecting the price of aluminum foil paper. Production costs include the costs of production equipment, labor, energy, production technology, etc., which will affect the production cost of aluminum foil and directly affect the price positioning.

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.
