The process of the row machine is similar for both the die line and the glass bottle mold line, as they are done in a straight line. However, the manual machine doesn't require a straight line for its process.
The row machine clearly produces the cooling pattern printing on the bottom of the glass bottle, whereas the manual machine's production is less apparent and not as distinct.
The bulkhead print in the manual machine process cannot be observed at the bottom of the glass bottle. However, in the row machine assembly line process, the bulkhead print is clearly noticeable at the bottom of the bottle.
Gather several glass bottles and compare those produced through the assembly line process to those made with a manual machine. The ones made with the assembly line process look precise and the angle of reflection is consistent, while the bottles made with the manual machine appear uneven on the surface.
The row machine produces glass bottles with a smoother and clearer body compared to those produced on the assembly line process. This can be attributed to the fact that the manual machine is water-cooled while the assembly line process is a combination of air and wind cooling. The smoothness of the glass bottles produced by the row machine is uniform and the bottle wall appears clearer and more transparent, giving a more premium feel to the product.
Hand-operated machines require a smaller minimum quantity compared to assembly line orders. Additionally, assembly line production is more suitable for handling large orders, which means that the investment in mold fees for this method tends to be higher.
Based on the original information, the manual machine is priced lower compared to the rank machine when it comes to glass bottle products.
