Coloring and plastic forming are two key processes in the manufacturing process of optical cable. The traditional manufacturing process can no longer meet the requirements of the current industry market competition. The faster

convenient

efficient and low-cost manufacturing mode is the current development trend

the future Intelligent manufacturing will be based on the energy-saving and environmental protection greenization

the system is highly integrated

and the process flow is extremely simplified. This paper will discuss the innovative practice of energy-saving production in the process of color cable and plastic molding in the manufacturing process of optical cable.
