what is aluminum disc circle for kitchen

Aluminum disc circle for kitchen is an aluminum material commonly used to make kitchen utensils. It is usually made of pure aluminum or aluminum alloy material, disc-shaped or round in shape, and has various diameters and thicknesses.

The main use of kitchen aluminum discs is to make a variety of cookware and cooking utensils, such as pans, woks, bakeware, and pressure cookers. This is because the aluminum disc has good thermal conductivity and uniform heat conduction performance, which can quickly transfer heat and make the food evenly heated.

Além disso, kitchen aluminum discs also have the advantages of lightness, easy processing and easy cleaning, which make it one of the indispensable materials in the manufacture of cookware and cooking utensils.

Aluminum alloy model

  • 1xxx: plasticity and conductivity, but low strength, mainly used to make packaging materials such as cans.
  • 3xxx: corrosion resistance and weldability, mainly used to make kitchen utensils, decorative materials, etc..
  • 5xxx: high strength, good corrosion resistance, good plasticity and weldability, mainly used to make kitchen utensils, ships, cars, etc..
  • 6xxx: high strength, good machinability, good corrosion resistance, mainly used to make various structural parts, body panels, etc..
  • 8xxx: with specific physical properties and application fields.

Processing technology

  1. Material preparation: choose the appropriate aluminum alloy material, and cut it into plates of appropriate size as needed.
  2. Mold design: According to the required size and shape of the aluminum disc, design the corresponding mold.
  3. Stamping forming: the aluminum plate is placed on the punching machine, and the aluminum plate is punched into the required shape through the stamping die to obtain the aluminum disc.
  4. Edge pressing: Place the aluminum disc on the edge pressing machine to press the edge of the aluminum disc to make it smooth.
  5. Polishing treatment: Use a polishing machine to polish the aluminum disc to make its surface smooth.
  6. Cleaning and packaging: Clean the oil and impurities on the surface of the aluminum wafer, then pack and mark.

surface treatment

Oxidation treatment:

soak the aluminum disc in the oxidation solution to form an oxide film on the surface.

The oxide film has a certain hardness and corrosion resistance, which can protect the surface of the aluminum wafer from oxidation, corrosion and scratches.

Anti-corrosion coating:

Coating the surface of the aluminum disc with a layer of anti-corrosion coating, such as epoxy resin, polyamide, etc., can improve its corrosion resistance and wear resistance.

Sand blasting treatment:

Spray the surface of the aluminum disc with sand particles to make the surface rough, which has certain anti-slip and decorative properties.

Polishing treatment:

The surface of the aluminum disc is polished by mechanical or chemical methods to make the surface as smooth as a mirror and has a good decorative effect.

Electrochemical polishing:

Micro scratches are formed on the surface of aluminum discs by electrochemical methods to make the surface smooth and uniform, which has certain anti-corrosion and decorative properties.

Properties of the aluminum circle:

Aluminum circle is suitable for many markets, including cookware, automotive and lighting industries, etc., thanks to good product characteristics:

  • Low anisotropy, which facilitates deep drawing
  • Strong mechanical properties
  • High and homogeneous heat diffusion
  • Ability to be enameled, covered by PTFE (or others), anodized
  • Good reflectivity
  • High strength-to-weight ratio
  • Durability and resistance to corrosion

  • Prepare the master alloys
  • Melting furnace: put the alloys into the melting furnace
  • D.C.cast aluminum ingot: To make the mother ingot
  • Mill the aluminum ingot: to make the surface and side smooth
  • Heating furnace
  • Hot rolling mill: made the mother coil
  • Colding rolling mill: the mother coil was rolled as the thickness you want to buy
  • Punching process: become the size what you want
  • Annealing furnace: change the temper
  • Final inspection
  • Packing: wooden case or wooden pallet
  • Delivery

Quality Control

Assurance Below inspection will be done in the production.

  • a. ray detectionRT;
  • b. ultrasonic testingUT;
  • c. Magnetic Particle Testing-MT;
  • d. penetration testing-PT;
  • e. eddy current flaw detection-ET

1) Be free from Oil Stain, Dent, Inclusion, Scratches, Stain, Oxide Discoloration, Breaks, Corrosion, Roll Marks, Dirt Streaks, and other defects which will interfere with use.

2) Surface without black line, clean-cut, periodic stain, roller printing defects, such as other gko internal Control standards.

Aluminum discs packing:

Aluminum circles can be packed by export standards, covering with brown paper and plastic film. Finally, the Aluminium Round is fixed on a wooden pallet/wooden case.

  • Put the driers side the aluminum circle, keep the products dry and clean.
  • Use clean plastic paper, pack the aluminium circle, keep good sealing.
  • Use the snakeskin paper, pack the surface of the plastic paper, keep good sealing.
  • Next, there are two ways of packaging: One way is wooden pallet packaging, using the crusty paper packing the surface; Another way is wooden case packaging, using the wooden case packing the surface.
  • Finally, lay the steel belt on the wooden box’s surface, keeping the wooden box fastness and secure.

Aluminum circle of Henan Huawei Aluminum. meet the export standard. Plastic film and brown paper can be covered at customers’ needs. What’s more, a wooden case or wooden pallet is adopted to protect products from damage during delivery. There are two kinds of packaging, which are eye to wall or eye to the sky. Customers can choose either of them for their convenience. Generally speaking, there are 2 tons in one package, and loading 18-22 tons in 1×20′ container, and 20-24 tons in 1×40′ container.
