Recently, a well-known domestic mold manufacturing enterprise announced that it has made significant breakthroughs in the field of recycling and reusing aluminum extrusion molds for rail transit. The successful development of this technology not only significantly improves the reuse rate of aluminum extrusion molds, but also provides strong support for the green manufacturing and circular economy development of the rail transit industry.
1. Technological breakthrough: efficient recycling and reuse
Traditional aluminum extrusion molds are often directly discarded at the end of their service life, resulting in resource waste and environmental pollution. The recycling and reuse technology that has made this breakthrough can efficiently recycle aluminum alloy materials from waste molds through advanced melting, purification, and remanufacturing processes, and reuse them to manufacture new aluminum extrusion molds. It is reported that the material recovery rate of this technology is over 95%, significantly reducing the cost of raw materials.
2. Environmental benefits: reducing resource waste and carbon emissions
The recycling and reuse of aluminum extrusion molds not only reduces dependence on primary aluminum resources, but also significantly reduces energy consumption and carbon emissions during the production process. According to calculations, recycling 1 ton of waste aluminum extrusion molds can reduce about 4 tons of carbon emissions, which is of great significance for promoting the green transformation of the rail transit industry.
3. Economic benefits: reducing production costs for enterprises
For rail transit manufacturing enterprises, aluminum extrusion molds are important production tools, but their manufacturing costs are relatively high. Through recycling and reuse technology, enterprises can turn waste molds into treasures, significantly reducing the manufacturing cost of new molds. Taking a certain enterprise as an example, after adopting this technology, its mold procurement cost has been reduced by more than 20%.
4. Industry application: Supporting the lightweight development of rail transit
The rail transit industry is developing towards lightweight and efficient direction, and aluminum extrusion molds are key tools for manufacturing lightweight aluminum alloy car bodies. Through recycling and reuse technology, enterprises can obtain high-quality molds at lower costs and in a more environmentally friendly way, further promoting the lightweight design of rail transit vehicles.
5. Policy support: Circular economy becomes a national strategy
In recent years, the country has vigorously promoted the development of circular economy and introduced a series of policies to support the research and application of resource recycling and reuse technologies. The breakthrough in the recycling and reuse technology of aluminum extrusion molds this time is a positive practice in response to national policies, setting a model for green manufacturing in the industry.
6. Future prospects: Technology promotion and industry collaboration
At present, this technology has been piloted and applied in multiple domestic rail transit manufacturing enterprises, and has achieved significant results. In the future, with further optimization and promotion of technology, it is expected to achieve large-scale applications across the entire industry. At the same time, upstream and downstream enterprises in the industry will also strengthen collaborative cooperation to jointly build a circular economy industrial chain for aluminum extrusion molds.
The breakthrough in the recycling and reuse technology of aluminum extrusion molds for rail transit marks an important step for China in the fields of green manufacturing and circular economy. With the continuous maturity of technology and the gradual expansion of applications, this technology will inject new momentum into the high-quality development of the rail transit industry, while also contributing Chinese wisdom to the sustainable development of the global manufacturing industry.
