A "linha de montagem" is a manufacturing process where products are assembled in a sequential manner. Each worker or machine performs a specific task, contributing to the final product. This method increases efficiency and reduces production time, making it a key component in industries like automotive and electronics. The concept of the assembly line was popularized by Henry Ford in the early 20th century, revolutionizing mass production. By breaking down complex tasks into simpler steps, companies can produce large quantities of goods while maintaining quality. This system is still widely used today in various sectors around the world.
