Because of its light weight, good ductility, strong plasticity, good sealing performance and excellent corrosion resistance, micro spray aluminum cans have become the choice of most people in the packaging of aerosol products such as medical, personal products, household products, food, and industry. Especially in today's development of water-based products, micro spray aluminum cans have become a must-have for water-based products due to their excellent corrosion resistance. At present, it has become the main product of the aerosol industry, and most of the common micro-sprayed aluminum cans on the market start from small aluminum ingots or aluminum sheets, so let's take a look at its manufacturing process.
 

The production process of micro spray aluminum cans is more than one step, and it must be completed step by step to ensure its quality, so what are the specific steps? Here's what you know.
 

1. Lubrication: Stir the aluminum ingot or aluminum sheet thoroughly with lubricant, and then stamp, stamping the aluminum ingot or aluminum sheet into a cylinder with only one opening.

2. Trimming: trim one side of the opening of the aluminum cylinder to the required height, reduce the surface roughness, and prepare for the subsequent printing process.

3. Rinse: wash off the oil, aluminum powder particles, etc., apply a layer of coating on the inside of the aluminum can to prevent the contents from reacting with the aluminum, corroding the aluminum can, and printing the pattern on the outside (including primer, printing and glazing).

4. Molding: Make aluminum cans of different shapes and appearances, check if there are leakage points, wash off the oil stains, clean the oil tank, and then you can pack.

So how is the recycling method of micro spray aluminum cans? Here's what you know.

1. Crushing: The shape of the recycled miniature spray aluminum cans has been destroyed, and some of the imported waste micro-spray aluminum cans have been packaged into fragments, which need to be crushed before the paint layer can be removed.

2. Paint stripping: loose waste micro chemical spraying aluminum cans (including a broken waste micro intelligent spraying aluminum cans) directly and economically enter the paint stripping kiln for paint stripping, at the beginning, to supplement a certain amount of heat energy, after reaching a certain temperature, the heat energy mainly relies on the exothermic process of carbonization of the surface coating of the micro spray aluminum can. In the rotary paint stripping kiln, the paint layer of the micro spray aluminum can is carbonized, and it vibrates by itself during the rotation movement, and the paint layer falls off, and then it has to go through our own special vibration and equipment to let all the carbon particles fall off, and the temperature of the rotary kiln is controlled at about 500 degrees.

3. Packaging: Waste micro-chemical spraying aluminum cans are very thin, the burning loss in the smelting process is large, and some even reach more than 10%, in order to improve the recovery rate of aluminum smelting, it is necessary to reduce the surface area of waste and reduce the burning loss, and the packaging equipment can use domestic hydraulic balers.

4. Melting: The pretreated micro spray aluminum cans enter the smelting furnace for smelting, cooling into metal blocks, and then processing, more problems will appear in the process of the fourth step, only need to pay attention to the aluminum blocks after cooling and then processing metal blocks.
