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.

One of the primary determinants of the friction factor is the roughness of the inner surface of the pipe. Galvanized iron pipes often exhibit a relatively high level of roughness compared to other materials, such as PVC or copper. This rough surface can lead to increased turbulence in the fluid flow, resulting in a higher friction factor. Suppliers need to pay close attention to the manufacturing processes that can influence the surface finish of their pipes. Techniques such as improved galvanization methods or surface treatments could significantly reduce the internal roughness and thereby lower the friction factor.
