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.
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 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.
