Como é feita a LATINHA de ALUMÍNIO #Boravê

Summary

This video explores the fascinating process of aluminum can production, beginning in Amazonas and extending to Minas Gerais. The script takes the audience on a journey to show how raw materials like aluminum coils are transformed into cans, from the creation of the lid with precise machinery to the shaping and printing of the can body. The manufacturing process includes several detailed steps: from aluminum coils being shaped and stamped to the meticulous quality control measures. It also highlights the importance of recycling, precision, and technological innovation in creating cans for beverages like soda and beer.

Takeaways

• 😀 The production of aluminum cans is a multi-step process, involving the creation of both the body and the lid of the can.
• 😀 The aluminum used for cans is mainly recycled, with 80% of its composition coming from recycled materials, sourced from places like Pindamonhangaba.
• 😀 Aluminum arrives in large coils, which are processed into thin, flexible sheets for the body and lid of the can.
• 😀 The lid of the can, including its pull tab, undergoes a precise shaping process using large presses and intricate machinery.
• 😀 The manufacturing of the lid involves applying a food-safe sealant and ensuring no leakage by conducting multiple quality tests.
• 😀 The pull tab of the can is made from a stronger aluminum, and it is coated with a special material for easy handling during the manufacturing process.
• 😀 The aluminum can undergoes various testing methods, including checking for leaks, durability under pressure, and ensuring the sealant and coatings are correctly applied.
• 😀 During the lid formation process, various tools and machines with different functions work together in synchronization to create the final product.
• 😀 In the second phase of the process, the can body is made from large aluminum coils, and the shaping is done using multiple presses to form the initial cup shape.
• 😀 After the initial cup is formed, the can undergoes additional processes where it is stretched and shaped into its final form, with high-speed machines ensuring rapid production.
• 😀 The cans undergo quality control, including visual inspections, pressure tests, and automated checks for imperfections, ensuring only the highest quality cans are produced.

Q & A

What are the main materials used in the production of aluminum cans?

The primary material used in the production of aluminum cans is aluminum, with 80% of the composition being recycled aluminum. The aluminum is sourced from Pindamonhangaba and transported via the Port of Santos to Manaus.

How is the process of making the aluminum can lid initiated?

The production of the aluminum can lid starts with large aluminum coils weighing up to 10 tons, which are processed to create the lid components. These coils are thin and malleable and are coated in either gold for beer cans or silver for soda cans.

What role does the 'sealant' play in the aluminum can production process?

The sealant is a type of adhesive applied to the junction between the body of the can and its lid to ensure that no liquid leaks from the joint. This sealant must be food-safe as it comes into direct contact with beverages.

How is the aluminum sheet shaped into the can lid?

The aluminum sheet is cut and shaped into the can lid using a press that molds the aluminum into the correct form. The process includes the formation of a smooth edge and the cutting of the aluminum into the shape of the lid.

What is the function of the 'pull tab' on the can lid?

The pull tab on the can lid is made from a stronger, narrower strip of aluminum designed to withstand the pressure applied when opening the can. It is made from a thicker material to handle the force applied by the user.

How is the aluminum sheet processed to form the body of the can?

The aluminum sheet is first cut into circles and then pressed into a cup-like shape using a machine. The cup is further stretched and thinned out through a process that involves passing the cup through multiple stages of pressing and stretching.

What is the significance of the 'code' stamped on the can lids?

The code stamped on the can lid includes a set of numbers and a letter indicating the manufacturing location, the machine used, and the month of production. This helps track the production process and ensures quality control.

What is the purpose of the quality tests performed on the aluminum can lids?

The lids undergo several quality control tests, including checks for proper application of the sealant, testing for leaks with compressed air, and ensuring the structural integrity of the lid. Lids that fail the tests are discarded.

How does the machine ensure the aluminum can remains intact during production?

The machines apply high-pressure tools and processes to shape the aluminum while maintaining its integrity. Specific tools, like a hammer made from copper, are used to prevent damaging the pieces during handling, ensuring smooth and flawless production.

What are the steps involved in the final production stage of the aluminum can?

In the final stages, the aluminum can is washed to remove any oils, printed with the desired design, and then coated with a protective layer to prevent the beverage from coming into direct contact with the aluminum. The neck of the can is also formed, and it is tested for defects before being ready for beverage filling.
