The factory process behind metal lunch boxes often involved a series of intricate steps. First, the raw materials were sourced and cut into the appropriate sizes. Next, the metal sheets underwent printing, where vibrant colors were applied to create eye-catching designs. The pieces were then shaped, bent, and fused together, creating a sturdy construction that could withstand the rigors of daily use. Finally, a protective coating was applied to guard against rust, ensuring these lunch boxes would endure for years.
