This blog can give you an insight into the production process of aerosol aluminum cans.

The Raw Material - Aluminum

The production of aerosol aluminum cans begins with high-quality aluminum. Usually, aluminum ingots are the main starting material. These aluminum ingots need to meet certain purity and mechanical property requirements to ensure the strength and safety of the final can.

Raw material—aluminum ingot

Production Process

Fried Slices

Extrusion: The aluminum is put through an extrusion process to form a long cylindrical aluminum tube.

Stamping and Drawing: The aluminum tube is then cut into appropriate lengths and stamped and drawn to form the basic shape of the can body, including the bottom and the side wall.

Trimming: After stamping, the edges and excess parts of the aerosol aluminum cans are trimmed to ensure accurate dimensions and a smooth appearance.

(Internal Treatment)

Cleaning: The inside of the aerosol aluminum cans is thoroughly cleaned to remove any impurities, oils, or dirt.

Coating: This coating is crucial as it prevents the contents of the aerosol from reacting with the aluminum and ensures the stability and safety of the product.

(External Processing)

Printing: The desired patterns, logos, and product information are printed on the outer surface of the can. Advanced printing techniques are used to ensure clear and durable printing.

Varnishing (Optional): Some cans may go through a varnishing process to enhance the gloss and protection of the printed surface.

(Assembly)

The can top is prepared, which often includes a valve mechanism for aerosol discharge. The top is then firmly attached to the can body through techniques such as crimping to form a sealed aerosol can.

(Quality Inspection)

Visual Inspection: Check for any defects in appearance, such as dents, scratches, or improper printing.

Leak Testing: Ensure there are no leaks in the aerosol aluminum can to prevent the aerosol from escaping or air from entering.

Pressure Testing: Test the can's ability to withstand the designed internal pressure.

Aerosol products have four main components, aerosol cans, valves, material, and ejector gas. Due to the differentiation of product formulations, we often need to consider the corrosiveness and pressure resistance between the filled material and the container when choosing the package. We know that there is a water-based aerosol product, which is highly corrosive to the can. So filling water-based aerosol products the key issue is the corrosion of the can, and the quality of the aerosol can directly affect the corrosion resistance. Factors affecting the quality of aerosol cans, from raw materials, can-making equipment and processes to quality testing, there are many, the following brief introduction.

1.The quality of tinplate itself

Tinplate base material used in the manufacture of cans requires high purity, such as impurity content is too high, affecting the ductility, brittleness, hardness and other processing properties and corrosion resistance, at present, most of China's tinplate base material imported from abroad. Some manufacturers in order to reduce costs, the use of low-quality thin tinplate cans, tinplate itself has tiny holes in the sand, resulting in leakage of the cans, the selection should pay special attention to.

2. Can body welding and coating quality

For Aerosol Tin Cans, one of the weaker links is the weld, in addition to the strict requirements of mechanical properties, the weld is easily corroded due to the destruction of the tin layer, and thus the filler coating is a three-piece cans of a key technology, a lot of water-based products leakage cans are due to the filler coating and the contents of the incompatibility caused by. In addition, the current is unstable or unstable quality of copper wire, etc., are easy to product welding, the formation of leakage points.

3.The type of internal coating and densification

Internal coating is one of the effective anti-corrosion method of water-based products (except DME as a propellant), but the quality of the internal coating material itself and the coating process will affect the corrosion resistance of the product, such as the coating of some of the naked eye is not easy to find bubbles, the electrochemical reaction is particularly strong in these places, over time it is easy to corrosion and rust so that wear cans, especially in the top and bottom of the lid and the weld contact with the tank body in the cans are prone to produce damage! In addition, the denseness of the coating is more important, many water-based products leakage of cans are present in this place. Currently used in the internal coating of epoxy a phenolic, imide an epoxy, PVC and other types, the use of more epoxy a phenolic, but the quality of different manufacturers are different, the selection should be good compatibility test.

4.Sealing quality 

Good sealing equipment and process is an effective guarantee of the sealing performance of aerosol cans, volume sealing of the hook and loop is an important indicator of the test, if the control is not good (including production processes and testing), it is easy to seal the imperceptible micro-leakage.

5.Leak detectio 

Aerosol products are mostly flammable and explosive products, each factory aerosol cans must be tested by the online pressure leakage detection machine, while the deformation pressure and burst pressure must be carried out in accordance with the provisions of the sampling to ensure the safety of the product production, storage, transport, use. Some manufacturers in order to reduce costs, not in accordance with the provisions of the leak detection, these cans are very likely to exist in the quality or safety hazards. 

6. Sealant

Aerosol cans and cans between the lid by the sealant in order to achieve the sealing requirements, the choice of a good sealant and coating process is critical to the quality of the can, in addition to the quality of the sealant itself should be strictly controlled, the sealant on a variety of solvents, especially strong solvents, DME and other solvency, dissolution, dissolution of the performance of the strict, long time to carry out the test, otherwise it will appear to destroy the sealant and leakage, there have been some of the can factory to appear such a situation. This situation has occurred in some can factories. When applying glue, the broken glue or uneven distribution, blistering, insufficient amount of glue applied, etc. are prone to problems. Due to the aerosol contents are very different, plus the sealing performance can not be determined within a short period of time, the quality of the sealant can only be guaranteed through the long time production experience of the can manufacturer and strict quality control.

From the above points we can know, regardless of the production of which aerosol products, the choice of packaging containers is very important, we not only need to consider the corrosiveness of the contents, but also need to consider the pressure resistance of the can, because the aerosol products belong to the pressure of the product, the filling pressure will be too big burst cans, the pressure is too small may not be able to achieve the desired effect of the spray. Therefore, we need a reasonable combination of product characteristics to choose the right aerosol cans!

What performance tests are required for aerosol cans？

1. Appearance Quality

Visually inspect the sample under natural light, including checking for defects, imperfections, and other inspection items.

Testing: The purpose is to record the physical appearance of the sample to determine if the aerosol can is flat and free of rust spots. Aerosol can with internal coating, the internal coating should be uniform and free of protrusions and impurities. The printed graphics and text are clear and complete, with no obvious scratches on the main parts.

2. Size

The height of the can body, total height, crinkle height, the outer diameter of the aerosol can opening, the inner diameter of the aerosol can opening,the outside dia of the double seam and height of the double seam should all be within the specified deviation range.

Testing: You can learn about the specifications of the aerosol cans you produce and whether they meet the technical requirements for sealing samples

3. Integrity of weld coating

The integrity of weld coating refers to the coverage area of the weld coating and the adhesion performance between the coating and the substrate, used to protect the weld and its surrounding areas from corrosion and environmental damage.

Testing: Integrity testing of weld coating can detect defects in both weld and coating, such as porosity, inclusions, cracks, and other defects inside the weld, or defects such as bubbles, peeling, and pitting on the coating surface. If these defects are not detected and addressed in a timely manner, they may affect the sealing and safety performance of the aerosol can, and even lead to serious accidents such as aerosol can explosions.

4. Adhesion of inner and outer coatings of aerosol cans

The adhesion between the inner and outer coatings of aerosol cans refers to the adhesion performance between the coating and the substrate, which is an important parameter of coating performance.

Testing: Internal and external coating adhesion testing can ensure that the adhesion performance between the coating and the substrate meets the standard requirements, avoiding the occurrence of coating peeling, cracking, or detachment. This can not only extend the service life of aerosol cans, but also improve their safety and reduce potential hazards.

5. Hardness of the outer coating of the aerosol can

The hardness testing of the outer coating is to ensure the wear resistance and scratch resistance of the surface of the aerosol can during use.

Testing: The outer coating hardness test can evaluate the hardness and scratch resistance of the coating, thereby determining the quality and durability of the coating. In addition, the hardness test of the outer coating can also detect quality issues of the coating, such as possible defects such as air bubbles and sagging, which may cause coating detachment or surface damage, thereby affecting the safety performance of the aerosol can.

6.Air tightness performance of aerosol cans

Airtightness performance testing refers to determining the airtightness performance of an aerosol can under pressure differences inside and outside the can by testing its sealing performance.

Testing: Aerosol cans need to withstand a certain amount of pressure during use, so their sealing performance has a significant impact on their safety and service life. If the airtightness performance is poor, it may lead to excessive internal pressure or leakage of the aerosol can, thereby causing safety accidents.

7. Deformation pressure

Deformation pressure testing refers to the pressure testing of an aerosol can to determine whether it can withstand a certain amount of pressure deformation without breaking.

Testing: During use, aerosol cans may be affected by external forces such as collision, compression, etc. If the structure of the aerosol can cannot withstand a certain amount of deformation pressure, deformation or rupture may occur, leading to safety accidents.

8. Burst pressure

Burst pressure testing refers to the process of conducting pressure tests on aerosol cans to determine their maximum allowable pressure.

Testing: During the use of aerosol cans, due to changes in pressure and environmental influences, the internal pressure may suddenly increase, leading to serious accidents such as explosions. Therefore, when manufacturing aerosol cans, it is necessary to conduct a burst pressure test to ensure their safety performance within the normal operating pressure range.

Compatibility and hygiene requirements testing can be conducted based on customer requirements and product properties.
