The Terminal Block Industry: Practice And Exploration Of Green Development
Driven by the acceleration of global electrification and the "dual carbon" goal, the terminal block industry is undergoing a critical stage of transitioning from traditional manufacturing to green and low-carbon. As the lifeline of the electrical system, terminal blocks have built a new path of sustainable development through material innovation, process upgrading, and circular economy models.
Material Innovation: From Stone based to Biocycling
Leading companies in the industry have taken the lead in breaking through material bottlenecks. The 221 green series terminal blocks launched by Wanke Electronics are made of 77% bio recycled polycarbonate for their insulation shell. The raw materials are sourced from food and paper industry waste and have passed the international sustainable development certification (ISCC+). The carbon dioxide emissions during the production process are reduced by 87% compared to traditional materials. Phoenix Contact has developed a terminal operating rod containing 27% recycled PET, which converts marine plastic into high-strength structural components and achieves the goal of "turning waste into treasure". Domestic enterprises such as Huaxi Technology have increased the conductivity of copper terminals by 15% and reduced production energy consumption by 20% by adding recycled copper and halogen-free flame retardants.
Process Upgrade: Energy Conservation and Consumption Reduction Throughout the Entire Cycle
The industry optimizes production processes through intelligent manufacturing technology. Weidmuller Group has introduced an AI energy management system to monitor the energy consumption of injection molding, stamping and other processes in real time. The energy consumption per unit product is 18% lower than the industry average. Domestic manufacturers adopt cold pressing connection technology instead of traditional welding, reducing 90% of exhaust emissions, and extending product life by 30% through modular design, reducing resource consumption throughout the entire lifecycle.
Circular Economy: From Linear Use to Closed Loop Regeneration
Top enterprises are building a closed-loop system of "production use recycling". Wanke Electronics' straw paper packaging is made by mixing 30% grass fiber with 70% recycled paper, and the raw materials are taken from ecological compensation grass, which saves 40% of water compared to pure recycled paper production. Phoenix Contact has launched a "trade in" program, where recycled old terminals are sorted and crushed before being refined into recycled plastic raw materials, forming a resource recycling chain.
Currently, the global terminal block market is expected to exceed billions of dollars, and the proportion of green products is increasing year by year. Through the triple innovation of materials, processes, and modes, the industry not only meets the market's demand for high-performance and low emission products, but also interprets the "big environmental protection" value of "small terminals" through practical actions.
