Spray cans are made of different materials such as glass, plastic and aluminum. Glass spray cans are mostly used in the manufacture of eau de toilettes and perfumes, and plastic sprays are not used much because they do not decompose in nature and cannot be recycled. But aluminum spray cans are used more in recent years due to their degradability and recyclability. But making aluminum spray requires advanced technology.
Packaging Industry
One of the most important branches of the industry is packaging, without using packaging for products, neither the brands have the ability to introduce themselves to the supporters of their products, nor will the products remain healthy when they are moved and released to the market. Today, the packaging industry tries to introduce different products to people in the best way by integrating visual arts and golden ratio in packaging. But product packages are usually left in the nature after consumption, so experts in this profession thought of using recyclable materials such as various metals.
Metal packaging is a type of packaging in which, instead of using materials that harm nature (such as plastics or toxic polymer materials), recyclable and healthy metals such as aluminum, stainless steel, or even nickel is used.
Now, among all the metal packaging available in the market, these are the spray can packaging, which is one of the best and most popular due to its high application and use. The type of packaging has changed. Making metal cans requires advanced science and technology, which unfortunately is not available in Iran.
Spray cans
Spray cans are used in different products and help in different areas. Cosmetics and hair care products use spray cans. Also, air fresheners need spray packaging cans. The paint and painting industry of buildings or cars use spray cans for paints. The use of spray cans are used in making asthma sprays that are medical.

Since the production of spray cans has decreased significantly in recent years, and as a result, finding these cans has become a major problem for perfume companies, you can enter this less competitive market. , and investing in it, achieve significant success. In the rest of this article, we will try to explain everything you need to know to produce and make a spray can.
Recent studies show that the amount of production of this product in the world has decreased. Nevertheless, a country like Türkiye continues to produce successfully in this field. Many countries, especially Iran, are willing to import cans produced in Turkey.
Production of spray cans can be made of steel, glass, plastic and aluminum. Aluminum cans are more popular among manufacturers.
Why do manufacturers prefer aluminum cans?
The first thing is that aluminum cans are recyclable and decompose in the heart of nature. These cans are more stable than other cans. which makes the customer use his spray for a longer time. In addition, aluminum has a great value in the packaging market due to its lightness.
How to Production
In order to be able to examine spray cans more professionally and accurately, we must first examine how these cans are produced and made. As we mentioned above, plastic spray cans are not of high quality and are not useful for many products. For this reason, in this section, we examine the main parts of the aluminum spray can production line:
The first step
For production, you must first prepare a large aluminum sheet and use a cutting machine to make round cuts on it.
Second step
Put the cut circles in the special forming machine to bend it by applying pressure to produce an aluminum spray can
Third step
In this step, to recycle the excess cuts, send them back to the manufacturing plant to melt them and turn them back into aluminum rings.
Step 4
You will place the bent shape of the cans in another machine to pull and lift it by applying force. At this stage, the body of the can has taken its true shape.
Fifth step
In this step, we deal with the process of sterilizing the produced cans. To wash aluminum cans, it is enough to put them upside down in the washing part of the cleaning machine. This machine cleans the cans without human intervention.
Step 6
After sterilizing the cans, they are directed to the drying machine and after drying exposed to hydrofluoric substance. This combination creates a thin cut on the surface of the can and makes it shiny.
Seventh step
In this step, according to the dimensions of the can and its special use, cuts are made at the beginning and end of the can.
Eighth step
After cutting the beginning and end of the can, its lower part is bent by applying the pressure of the machine, and if there is a need to create a groove in its design, a groove is embedded in it.
Ninth step
In this step, we need a stapler to connect the bottom and head of the can to its body.
Tenth step
In order not to leave cracks or seams in the cans, the cans are placed in a high temperature device. which brings aluminum closer to the melting point. This causes the seams in the can to be filled with molten aluminum
