Metal packaging, especially canning have provided the world with a very efficient way of packaging food products compared to other means such as plastic and other materials which as less sustainable and inefficient in cost saving.

Tin Can Production Line

Tin Can Production Line

Making a tin can entails a series of process that integrates to ensure the final product is apt and timely. A can making machine delivers cans of various shapes, sizes and can be adjusted to meet your preferences. There are various can shape including the round, rectangular, square and other irregular shapes that suit your customized necessities.

There are various production lines available, these include rectangular car line, round car line, mints car line and irregular can line. In rectangular can line for instance, can maker machines incorporated include can body machine, slitting machine, beading machine,  top curling machine, necking machine, seaming machine, flanging machine, bottom making machine and lid making the machine.

Can Production Line

In the production of tin cans, various processes are followed before obtaining the final product. These steps are distinctive, and with the help of multiple machines, this process is made simpler and production of cans increases at the same time.

Shearing/slitting Machine

Production of tin can begins with the slitting or shearing machine. A tin plate is a raw material, and the slitting machine precisely cuts this plate into blanks. The blanks obtained should be of desired width and lengths so that it can be fabricated later into a single body with a lid and bottom. Shearing process can be done manually, or it can be fully automated. The main types of slitting machines that can be effectively utilized in this process include manual, semi-automatic, and full automatic shearing/slitting machine.

Can Body Maker Machine

In this step, several processes are incorporated at the same time. This car maker machine has been entirely programmed and produces many finished tin can bodies at a short time. The manufacturing process incorporated in this step includes notching, making a grove, locking, forming and pre-curling. The body making process should be fully automated to cut down the production cost. Also, this machine can be adjusted to produce various body shapes and sizes.

Top Curling Machine

This machine curls the top of the tin can. This will make the can to have the desired shape with a specific depression. When this machine is incorporated, a fine rim will be obtained at the top.

Necking Machine

This machine typically reduces and lessens the diameter of the can’s top. It constricts the top to be narrow compared to the rest of the can body. This machine will also improve the appearance of the can.

Beading machine

A beading machine is generally responsible for instilling a unique series of bulges and depressions. The beading process will furnish the can and improves its quality.

Flanging machine

A flanging machine is designed to flange the bottom and top ends of the tin can. When using this machine, the bottom and top are appended.

Seaming machine

A seaming machine will join the body and the bottom of the can. This can be done either through single or double seaming.

Lid Making Machine

This process deals with edge curling, punching of the blanks and trimming. A lid will be produced that is ideal for the size, shape, and design of the can.

Bottom Making Machine

When making the bottom of the can, bottom sections are obtained by punching the blank slits and then seamed at the lower end to get a tin can.

Types of Metal Cans for Packaging

Types of Metal Cans for Packaging

Canning products is among the current popular way of packaging items especially food. The kind of food being packaged determines the type of can to be used. Metal cans are categorized into three groups depending on their structure, materials used and the degree of internal pressure. Can manufacturers are guided by these qualities in their production line to process the tins using the can making machine. The structure can either be 3 piece cans or 2 piece cans. The common material includes aluminum and steel. The internal pressure can be in the form of vacuum cans or pressurized ones. The article will, however, focus on the 2 piece and 3 piece classification of metal cans.

2 Piece and 3 piece cans

The 2 piece cans comprise two components. The first includes the integration of the body with a bottom lid and the second is possession of a lid with an opening. The 3-pieces cans, on the other hand, consist of three components. The first is a bottom lid; second is a cylindrical body and the third is the top lid. These components are produced separately and then later attached using a technique referred to as double seaming. For the 3-piece cans, they are crafted from a rectangular metal sheet, rolled into a cylinder and then soldered or electric welded. The most common are the welded cans as they are cheap to manufacture.

Manufacturing of 3-piece cans

These are the common types of tin cans used in the market. Although some of the plate used for making 3-piece cans is first coated with tin then oven-dried, there are pure tin cans in the market. The plate is then cut into the desired sizes and shapes for further processing. It is then folded into a longitudinal cylindrical body while the bottom and the lid are also made. The tubular can without any content is referred to as a blank. When filled with the intended content, the cans are air-tight sealed through the crimping process. The can-sealing machine is used for this function. After sealing, the cans are sterilized or pressurized in an autoclave to induce non-perishability.

2-piece cans

The 2-piece metal cans consist of an integration of a bottom lid and top lid with the body with the aid of a can making machine. The processing of the can body is categorized into Draw and Redraw cans (DRD) and Draw, and Wall ironed cans (DWI). The 2-piece cans are usually hermetically sealed with a design to maintaining the freshness of the content packed inside. The food items packed in these cans retain their color, taste, and flavor. They can also be used for instant packaging of products that does not require thermal processing before consumption.

So if you are planning to buy a tin can making machine production line to produce your own tin cans, you need to understand the kind of cans that you need. Check whether the can maker machine is able to produce such can to avoid the expensive return process.

Aluminum vs plastic vs glass

Aluminum vs plastic vs glass

A can making machine is a designated machine meant to make cans. Can usually come in different materials; these include aluminum cans, plastic cans, and tin cans. Making these cans also involve different ways; for instance, tin cans can be achieved through lock seaming or welding. Processing industries use cans for packaging juices and soft drinks for easy storage and distribution. However, depending on the material, it has advantages and disadvantages including the impact on the environment.

Making a plastic can

The material used in making plastic cans is mainly PET. Like other plastics, PET is manufactured from non-renewable petroleum and is made up of long chains of carbons. PET products such as bottles are made through processes like stretch blow molding and injection method. In this case a plastic material is injected through molding and finally extruded using air pressure to achieve the desired shape.


A glass is made from non-renewable products such as silica, sand, and limestone. Compared to petroleum products, glass adds less environmental damage during extraction. During the manufacturing, high amount of energy is required of up to 1200 degrees Celsius to break down elements.

Aluminum Cans

On the hand, aluminum cans are made from elements like bauxite. It is mined through dredging mines or open-pit and they also have some damaging environmental impacts. However, about 40-70 percent of aluminum products are recycled. Unlike the aluminum virgin material, when content is recycled, it uses 90 to 95 percent less energy. While in glass bottles, about 75 percent of energy is saved when recycled.

A research done in the United States indicates glass bottles disposed of has a high environmental impact compared to aluminum cans. It also has climate change potential of about 23 percent. When you compare the three, PET plastic bottles have the lowest impact on global warming while the glass bottles and aluminum can have 40 and 23 percent potential on global warming respectively.


When it comes to weight, glass material weighs much higher than the other two materials. For instance, a middleweight PET bottle usually weighs 24g while a 335ml aluminum can weigh 11g. So taking into account the weight of transporting these materials, aluminum and PET bottles are more suitable.

When choosing a can making machine, you should first take into account the nature of the bottle you want. Some are rectangular, round bottom, and others have irregular shapes. Depending on your preferences, always go for the best that features automatic functionalities.

Comparison of Tin Cans and Aluminum Cans

Comparison of Tin Cans and Aluminum Cans

With the help of can making machine, production of tin cans has become extensively easy. This process goes through a series of tin can making machine production line that mostly has been integrated into one process. Normally the first step involves slitting process where the body, bottom, and the lid plates will be obtained. Then there is a can body making machine that operates automatically to make the body of the tin. Then top curling is done followed by necking, flanging and finally seaming.

The widely used cans are made of tin and aluminum. However, these two types do not have the same properties. Although most industries use them for general packaging process, they usually undergo different manufacturing process.

The inception

Tin cans were first used for storage purposes in the 1810s while the aluminum was introduced in 1965. These two types of tins have many uses, but the primary goal was to be used for preserving food products for local and overseas consumption. These two types protect food from the air and light. They are also durable and can be recycled.

Tin Cans

Tin cans are usually malleable at room temperatures because they are made up of the crystalline metallic element. They are extracted from elements like cassiterite, a tin compound and also oxygen. The refining process of tin makes it ideal for manufacturing. It does not corrode easily, and that is why it is useful for packaging food products. Some of the modern tin cans have steel coating and a layer of the tin to make it corrosion-resistant.


Aluminum is relatively cheap mineral element when you compare with other minerals. This is because they are available abundantly and makes up to 8.2% of the earth’s crust. However, refining aluminum is a bit complex as it has other compounds such as aluminum oxide or aluminum sulfate. Most of the cans made of aluminum are lightweight and robust.


One of the main differences between the two is the weight. The tin cans are relatively heavier than aluminum and are usually durable. They are resistant to corrosion making it ideal for foods that are acidic like tomatoes. However, when it comes to recycling, the aluminum cans are more efficient. You will save a lot of money when you recycle aluminum unlike when you refine the new ones.

When making tins, ensure that you buy a can making machine that is fully automated and integrated for ease of use.
