Mixing galvanized and black iron pipes within the same system can present several challenges. One of the primary concerns is galvanic corrosion, a phenomenon that occurs when two dissimilar metals come into electrical contact in the presence of an electrolyte, such as water. In this scenario, the zinc coating of the galvanized pipe can corrode at an accelerated rate due to the electrical activity created by the differing materials. As a result, the lifespan of the system may be significantly reduced, leading to potential failures and costly repairs.

After stamping, the raw pieces undergo the painting process. Factory workers apply vibrant colors using techniques such as lithography, which allows for detailed and intricate designs to be printed directly onto the metal. These colorful patterns are important for attracting young consumers, making the tin cars appealing and engaging. Once painted, the cars are assembled, with various parts – like wheels and springs – being attached to give them life. The assembly line, a hallmark of modern manufacturing, allows for efficiency while still maintaining a level of craftsmanship that ensures quality.

Once the wire is drawn, it undergoes cleaning to remove any impurities or oxidation that may have occurred during the drawing process. After cleaning, the wire is then subjected to the galvanization process, where it is coated with zinc. Factories ensure that the coating adheres properly, providing excellent corrosion resistance.
